A discovery call ends well. The person on the other end sounded convinced. You both said something like “this feels right”. Then they went back to a Tuesday afternoon with eleven other things in it. By Thursday all they have left is a warm feeling, and a warm feeling loses to a look at the bank balance.
The follow-up email gives the conversation a shape. It says what you heard them ask for, what you’d do about it, what that costs, and the single next thing that has to happen. It’s a short message. It also carries most of the weight in the sale, because it’s the only part of the sale the buyer can read twice.
A few things worth knowing before you draft.
- Your job is to make a decision possible. A follow-up that argues is talking to an empty room.
- Reflecting back what they said, in their words, is the largest single piece of the email. Everything else is logistics hung off it.
- The price goes in. All of it, in numbers, with the terms. A follow-up that withholds the number buys itself one more email and spends the client’s goodwill to do it.
- Professional and legal rules are already running here, before anybody has agreed to anything. They’re light, and two of them get broken constantly.
This piece covers the message you send while the answer is still open. Once they say yes the job changes, and it becomes the welcome email that builds trust. The message that goes out before the call, when somebody first asks for one, is answering a discovery call request the same day. If you’re selling a scoped project with deliverables rather than an ongoing coaching engagement, the shape is different enough that following up on a proposal fits you better than this does.
The job this email has
A discovery call is usually free, usually short, and usually the only time the two of you talk before money changes hands. Whatever it settled, it settled out loud. Out loud fades inside a week.
The email has three jobs. The first one is most of the work.
Show them you heard it. The two or three things they said they wanted to be different, written in the words they used rather than the words you’d use. A client reading their own sentence back, slightly tidied, has evidence that the half hour was actually spent on them. A list of credentials supplies nothing like it.
Make the offer legible. What you’d propose, how long, how often, and what it costs. Coaches soften this part. Softening it produces the four-email thread where the buyer tries to find out the price while staying polite.
Leave exactly one thing to do. A link, a reply, a signature. One. A second next step turns the reply into a decision about how to decide.
Persuading sits outside this email’s job. The persuading already happened, in a conversation where you could hear them. A written argument arriving afterward reads as somebody who distrusted the conversation.
What already binds you, before anybody has signed anything
Most coaches assume the ethics start when the client starts. The ICF Code of Ethics starts earlier, in a sentence in its introduction that’s easy to read past. The Code “applies when ICF Professionals represent themselves as such, in any kind of coaching-related interaction. This is regardless of whether a coaching relationship (see definitions) has been established.” That text is the September 2019 code as it stands in the version marked rev. 06.25.21.
The definition it points at matters. A Coaching Relationship is “a relationship that is established by the ICF Professional and the Client(s)/Sponsor(s) under an agreement or a contract that defines the responsibilities and expectations of each party.” No agreement, no coaching relationship. The Code applies anyway. Your follow-up email sits exactly in that gap, and it’s the message most likely to be written in sales language borrowed from somewhere else.
Two standards land directly on this message.
Standard 20 asks the coach to “Identify accurately my coaching qualifications, my level of coaching competency, expertise, experience, training, certifications and ICF Credentials.” That’s the credentials line at the bottom of your email. An ACC is not a PCC. “Trained at” and “credentialed by” are different claims, and a certificate from a program is a different thing from an ICF Credential. The blurring happens on its own, the moment the sentence gets compressed for a phone screen.
Standard 12 asks the coach to “Disclose to my Clients the potential receipt of compensation and other benefits I may receive for referring my Clients to third parties.” That one’s for the follow-up where you say this isn’t a fit and here’s someone better. If a referral fee is attached, it goes in the same email, in a clause. More on that below, because it’s the message coaches get most wrong while feeling most generous.
Two limits, stated plainly. The Code reaches somebody presenting themselves as an ICF member or credential-holder, and for them it’s a membership rule rather than law. Its value is that it’s written down, and your buyer has probably heard of the body that wrote it. That makes it the nearest thing this trade has to a published account of what a prospect is owed in the week before they hire anybody.
ICF describes the same moment from the other side in its Core Competencies, the October 2019 update, currently carrying rev. 07.30.21. Competency 3 asks the coach to reach agreement about “what is and is not appropriate in the relationship, what is and is not being offered, and the responsibilities of the client and relevant stakeholders”, and separately to explain “what coaching is and is not”. Read those two as a specification for the middle paragraph of your follow-up. That’s what they are.
The one worth pinning above your desk is sub-point 5: “Partners with the client to determine client-coach compatibility.” That’s the whole point of a discovery call, stated as a joint activity rather than an assessment you perform on them. The follow-up email is where you write down the answer you both reached. The answer is allowed to be no.
When to send it
Same day. If the call ran late, the next morning before 10:00.
The reason sits with the client rather than with urgency. The version of them who says yes existed during the call, and that person fades. On the call they were describing their situation to somebody who was listening carefully, which is a state most people are rarely in. Two days later they’re back to their ordinary relationship with their own problems, which is to have stopped noticing them. The email arriving that same afternoon reaches the first person. The email arriving Friday reaches the second one.
There’s a practical reason too. You still remember the words. The specific phrase they used about their team, the thing they said and then apologized for saying. Twenty-four hours later you have a paraphrase, and a paraphrase does a fraction of the work.
If today is genuinely too full to write it properly, send four lines today saying it’s coming tomorrow with what you’d propose in it, then send it tomorrow. A short placeholder that keeps its own promise beats a good email that arrives on the fourth day.
Back-to-back discovery calls are the usual reason this slips. Book them with a gap after each one, rather than stacked. The mechanics of that live in letting a client book the hour you meant to give them.
The five parts, in the order they should land
What you heard. Two or three sentences, in their language. “You said the hard part isn’t the work. It’s that you’ve said yes to four things this quarter that you knew were wrong on the day you agreed to them.” Write one sentence they’ll recognize as theirs, and the rest of the email is read differently.
What you’d propose, and why that shape. The number of sessions, the length, the spacing, over what period. Then one sentence on why that shape, tied to what you just reflected back. Six sessions over three months is a claim about how fast the thing they described can move. Say so in half a line. This is where you write the boundary too: what the engagement is for, and what it leaves alone. Competency 3 asks for agreement on “what is and is not being offered”, and the follow-up is the last cheap moment to set it.
The price, in full. Its own paragraph, its own numbers. See below.
What happens next, once. The single action. “Reply and I’ll send the agreement and three times for the first session.” Or a booking link. Or a signing link. Pick one.
A date. A real one, rather than an invented one. How long you’re holding the slot, or when your next opening actually is. Or simply “nothing from you by the 19th and I’ll take it that the timing is wrong, and stop chasing you.” That last sentence does more work than any scarcity line, because it’s verifiable and it’s a kindness. It also gives you permission to stop, which is the thing most coaches actually need.
Length: one screen on a phone. The subject line names the thing rather than the relationship, because the client has to find this email again in ten days when they finally decide. “Coaching proposal, six sessions, October to January” is findable. “Great talking today” is unfindable, and the subject line’s real job is that retrieval.
Saying the price
Put the whole number in the email.
A range works only where the range is real and you say what moves it. Write the figure itself, rather than “investment” or “packages start at”. A link to a page with the number on it is the same evasion with an extra click attached. If you discussed the figure on the call, restate it anyway. A number said out loud stays out of reach, and a written one can be forwarded and acted on.
Around the number, four facts:
- What it buys, stated as the whole engagement rather than a per-session rate, if that’s how you actually sell it.
- When it’s due, and in how many payments. If there’s a schedule, put the dates in. Writing them here keeps the later conversation administrative if a payment slips, which is a craft of its own: handling a payment reminder gracefully.
- What happens to unused sessions, and what the cancellation window is, in one clause each. Both go in the agreement in full. In the email they exist so both of you meet them early rather than as a surprise later.
- Whether the price includes anything between sessions, such as email access. If it does, that’s worth a half sentence. Clients usually value it most and rarely think to ask about it. What that access looks like once it’s running is between-session check-ins that land.
Two things to resist. The first is discounting inside the follow-up. A price that drops between the call and the email teaches the buyer that the number was decorative, and the discount only closes people who were already close. The second is offering a smaller version unprompted. If the engagement you proposed is too big for them, propose the smaller one as the main thing rather than as a fallback. A fallback offered in the same breath makes the first one look inflated.
If they ask for something cheaper, that’s a real conversation and it’s worth having on its own. Have it on its own. The follow-up you already sent stays as it is.
When you are not the right coach
Sometimes the call answers the compatibility question the other way, and you know it before you reach your desk.
Send the email anyway, and send it fast. A follow-up that says no is the easiest email you’ll write all month, and the one clients remember for years, because so few coaches send it. Say what you heard. Say plainly that you’re the wrong person for it. Say why in one non-wounding sentence. Then give them a name if you have one.
Standard 8 of the ICF Code covers the mid-engagement version of this, asking the coach to “make a change in the relationship or encourage the Client(s) / Sponsor(s) to seek another coach, seek another professional or use a different resource”. The pre-engagement version is written down less clearly, which is odd, because it’s cheaper for everybody.
The part that does have a rule is the referral itself. Standard 12 requires the coach to “Disclose to my Clients the potential receipt of compensation and other benefits I may receive for referring my Clients to third parties.” Referral fees are ordinary in coaching networks and mastermind groups, and they read as a conflict the moment somebody finds out about one. The disclosure costs one clause in a sentence you were writing anyway: “Ana and I refer to each other and she pays me a fee if you work with her; take the introduction only if it’s useful to you.” A referral you can say that about is a referral. One you’d rather stay quiet about is a sale.
If what you heard on the call belongs with a therapist or a physician rather than a coach, say that with more care and less specificity. You’re pointing, rather than diagnosing. “What you’re describing sounds like it deserves more clinical support than coaching gives, and I’d rather say so now than take your money and find out in March” is a sentence you’re allowed to write.
How many times to follow up, and the message that stops it
Two more contacts after the proposal, then a message that closes the loop. Three total, spread over roughly two to three weeks.
The first chase goes about five business days after the proposal. Its job is to be short and to add one thing. “Just checking in” asks the client to restart a conversation you could have restarted yourself, so add a fact instead: the slot you were holding, a specific question, an answer to the thing they hesitated on. Then stop.
The second goes a week or so after that, and it’s the closing message. It says you’re taking it off your list, it says the door is open, and it names how to reopen it. Written properly, this one converts more often than the chase does, because it lifts the pressure that was quietly holding the reply back.
Then stop, and mean it. The general craft of a chase that keeps the relationship intact is following up without nagging, and how long to leave between touches in other contexts is how long to wait before following up.
Three habits to keep out of the gap. Frequency that rises as hope falls. A subject line engineered to look like a reply. And silence read as an answer about you: the most common reason an eager prospect goes quiet is that a different part of their life fell over. They’re embarrassed about the delay, and the embarrassment compounds it.
Where the follow-up stops being a reply and becomes advertising
This part rarely gets written down for coaches, and it’s the one with a dollar figure attached.
The CAN-SPAM Act defines a commercial electronic mail message as “any electronic mail message the primary purpose of which is the commercial advertisement or promotion of a commercial product or service”. A proposal for a paid coaching engagement is, on its face, exactly that. The statute carves out transactional or relationship messages. Read the carve-out before you rely on it. The relevant branch covers a message whose purpose is “to facilitate, complete, or confirm a commercial transaction that the recipient has previously agreed to enter into with the sender”, and the discovery call is the precise moment before they have agreed to enter into anything.
So on a plain reading, the three requirements at 15 U.S.C. 7704(a)(5)(A) attach:
- “clear and conspicuous identification that the message is an advertisement or solicitation”
- “clear and conspicuous notice of the opportunity under paragraph (3) to decline to receive further commercial electronic mail messages from the sender”
- “a valid physical postal address of the sender”
The Federal Trade Commission’s compliance guide is blunt that this reaches past bulk mail, and that “the law makes no exception for business-to-business email”.
Now the part that makes it livable. The advertisement identification requirement drops away where the recipient gave prior affirmative consent, under 7704(a)(5)(B). Affirmative consent is defined as the recipient having “expressly consented to receive the message, either in response to a clear and conspicuous request for such consent or at the recipient’s own initiative”. Somebody who booked a call with you and asked you to send them a proposal has a strong claim to have done the second of those. The postal address and the working opt-out stay in place. Those are two lines in a signature block, and a solo coach working from home can use a mailbox service rather than publishing a home address.
The single reply is the easy case. The sequence is where this genuinely bites. The moment a prospect who never bought is added to a newsletter, a launch list or an automated nurture series, you’re sending commercial email to somebody whose only ask was a proposal. Every one of those messages needs all three elements, and a working unsubscribe honored within 10 business days of the request. As checked on September 6, 2026, the FTC’s guide states that “each separate email in violation of the CAN-SPAM Act is subject to penalties of up to $53,088”. Per email. A twelve-message sequence sent to eighty non-buyers is a large exposure on paper. Enforcement in practice goes after volume operators rather than solo coaches, which is a reason to be calm about it and a reason to stay careful.
This is general information rather than legal advice, and if you’re building a list of any size it’s worth twenty minutes with somebody who does that for a living. The rule of thumb that keeps you clear: a reply to a conversation they started is a reply, and anything you’d describe internally as a campaign is advertising.
What you have to be able to back up
The other rule that lands on this email governs results.
The FTC’s Endorsement Guides were revised and published in the Federal Register on July 26, 2023 at 88 FR 48092. They define an endorsement as “any advertising, marketing, or promotional message for a product that consumers are likely to believe reflects the opinions, beliefs, findings, or experiences of a party other than the sponsoring advertiser”. A quote from a past client pasted into your follow-up email is one, and the email is marketing.
The rule that catches coaches is 16 CFR 255.2(b). An endorsement describing one client’s experience on a central attribute “will likely be interpreted as representing that the endorser’s experience is representative of what consumers will generally achieve”. Where substantiation that it is representative is missing, “the advertisement should clearly and conspicuously disclose the generally expected performance in the depicted circumstances”, and that disclosure needs substantiation of its own. So the escape hatch is being able to say what results generally are. A disclaimer saying results vary leaves you where you started.
Almost no solo coaching practice can substantiate that. Which points at the practical answer: keep the outcome claims out of the follow-up entirely. Describe the process, the shape of the engagement, and what you’ll work on. Keep “my last three clients doubled their revenue” out of an email to somebody who is still deciding, along with the testimonial about the promotion.
Your experience is still yours to state. Saying you’ve coached forty founders through a first management hire is a fact about you, and Standard 20 asks you to state that kind of thing accurately rather than sparingly. The sentence to avoid is the one implying the reader will get what somebody else got.
Five you can send
The price is written as $X in these, because yours is yours. Put the actual figure in everywhere it appears.
One. They said yes on the call.
Subject: Coaching, six sessions, October to March
Hi Priya,
Good conversation this morning. What I heard: the practice is full, you’re working every Saturday to keep it that way, and the thing you actually want back is the two evenings a week you used to have.
What I’d propose is six sessions over five months, 60 minutes each, roughly every three weeks. Five months rather than three because you’re changing a set of habits about who you say no to, and those move at the speed of the next time somebody asks.
The engagement is $X in total. Half on signing, half on February 1. Sessions can be moved with 48 hours’ notice; inside that they count as used. Email between sessions is included and I answer inside one business day.
One thing to do: reply and I’ll send the agreement and three times for the first session.
Dana
Two. They need to think, or talk to somebody.
Subject: What we talked about, and what it would cost
Hi Marcus,
Thanks for the half hour. You said the team runs fine when you’re in the room and stalls when you’re away, and that you’ve been avoiding the two conversations that would change that.
What I’d propose: eight sessions over six months, 60 minutes, every three weeks or so. The first two are spent on the two conversations specifically, because everything else you and I do rests on them.
Total is $X, payable in two installments, the second on March 1. Full terms are in the agreement, and the two worth knowing now are a 48 hour cancellation window and that unused sessions expire six months after we start.
Take it to Jenna and take the week. If it would help her to have the outline in writing rather than through you, tell me and I’ll send a version she can read.
I’m holding the Tuesday 4:00 p.m. ET slot until the 19th. Nothing from you by then and I’ll release it and stop chasing you, which is a promise rather than a deadline.
Dana
Three. An employer is paying and the person on the call is not the buyer.
Subject: Coaching for Sam: scope, cost, and what Ravi will see
Hi Sam,
Two versions of this, because two people need to read it.
For you: what I heard was that the step up to director happened nine months ago and nobody ever told you what the job actually is. Eight sessions over six months, starting in November.
For Ravi and the budget: the engagement is $X, invoiced in two parts, with a start and end date rather than an open commitment.
The part worth settling before anybody signs anything is what Ravi hears from me. My proposal is attendance, sessions used, and a one-page note at the end confirming completion. Nothing about content, topics or anything you say. If Brightline needs more than that, better to find out now, because I’d rather change the arrangement than surprise you with it in January.
Next step is yours: tell me whether that list of what I report back is the right one, and I’ll send the agreement to Ravi.
Dana
Four. It is not a fit.
Subject: Following up, and an honest answer
Hi Chloe,
Thank you for Tuesday. I’ve thought about it, and I don’t think I’m the right coach for this one.
What you’re working on is mostly a pricing and positioning problem with a confidence problem sitting on top of it. I’m good at the second half and genuinely not the first, and six months of me would circle the thing you actually need.
Two names, if useful. Ana Reyes does exactly this and does it well; she and I refer to each other, and she pays me a fee if you end up working with her, so weigh the introduction with that in mind. Tom Okafor pays me nothing, is also excellent, and is slower to reply.
If you want either introduction, say the word. If the confidence half turns out to be the whole of it in a year, come back.
Dana
Five. The message that closes the loop.
Subject: Closing this off, October to March coaching
Hi Marcus,
I’m taking this off my list, which is not a nudge. Timing is the most common reason these go quiet, and it’s a good one.
The Tuesday slot has gone to someone else. If you want to pick it up later, reply to this email with a month and I’ll tell you what I have; there’s nothing to redo and no form to fill in again.
The two conversations are still the ones worth having, with me or without me.
Dana
Three things run through all five. Each says what was heard before it says what’s offered. Each names the money, or names why the money is absent. And each leaves exactly one thing to do.
What to leave out
The recap of the call. They were there. Write back the two or three sentences that mattered.
Your credentials, at length. One line at the bottom, accurate to the letter. Standard 20 asks for accuracy, and it’s a floor rather than a marketing brief.
Anything that implies a result. Covered above. It’s the easiest sentence in the whole email to write by accident.
Urgency you invented. “I only have two spots left” when you have eleven is a lie told to a person you’re about to ask to be honest with you for six months.
A second offer. The cheaper alternative, the group program, the self-study course. Each additional option lowers the odds of a decision and raises the odds of a maybe.
An attachment nobody asked for. A twelve-page prospectus makes the reader responsible for finding your price inside it. If the agreement needs to travel, say so and send it after they say yes, which is the welcome email’s job.
“Let me know if you have any questions.” It ends the email and leaves the reader idle. Replace it with the single action and the date.
A calendar invitation for a session nobody has agreed to buy. It reads as presumption, and it’s genuinely awkward to decline.
What this email cannot do
A call that went badly stays that way. If the half hour was flat, the follow-up is a well written record of a flat conversation. Send it anyway, shorter.
An unaffordable price stays unaffordable. Restating the number more warmly leaves the number where it is. Propose something smaller as the main offer, or accept that this is another year’s conversation.
A decision needs somebody with the authority to make it. Where a manager or a spouse or a finance team is involved, the useful move is to ask who else needs to see it and write a version for them. Persuading the person you already persuaded goes nowhere.
The compatibility question belongs to the call. If you’re unsure you want this client, a second short conversation is where you find out. That was the call’s job, and you’re allowed to have missed it.
It has to reach the right person. The template with somebody else’s name half-replaced ends the sale on the spot, and it happens on exactly the days you have four of these to write.
Sending it on a day with four calls in it
The follow-up is easy to write once and hard to write six times in a week, because the day it’s due is always the day that’s already full. That’s where these go missing. The client stayed willing, the email stayed unwritten, and then it was too late to send.
Point runs on the Gmail or Microsoft 365 account prospects already write to. Point takes over the carrying, and the judgment stays with you.
The message starts as a thread rather than a blank page. Ask for it in one line and a draft comes back in your phrasing. The name, the dates and the numbers are already sitting in it. What’s left is the two or three sentences only you could write, which are the ones about what they said. Standing instructions are kept as plain sentences you can read and edit. Name the time zone. Put the cancellation window in the price paragraph. Keep the postal address in the signature of every proposal. A proposal stays a draft on your screen until you move a dial yourself. Each kind of work has its own position on that dial, which runs from suggest-only, through preparing something and holding it, to acting outright, and review is where every kind sits when you start. Anything done for you shows up in order in the activity log, and undo works back along it. The exception is the obvious one, and every product shares it: once a message has landed on someone else’s server, it’s out of reach.
Then Point holds the timetable you set. The five day chase and the closing message become dated tasks off the thread itself, rather than a note in your head. A proposal nobody answered comes back up your feed on the day you said you’d stop, rather than three weeks later when you happen to notice. A booking page offers only times you’re genuinely free, so the calls arrive with a gap after each one and the follow-up has somewhere to live. Once somebody says yes, Point runs the scheduling back-and-forth for the first session.
Stalling on whether to let software near a conversation this private is fair. The honest answer about what Point can and cannot see is in what it sees. Everything else Point changes about an ordinary working week is set out on the benefits page.
Common questions
What should I say in a follow-up email after a discovery call?
Five things, in this order. What you heard them say, in their words. What you’d propose, including how many sessions over what period and why that shape. The full price, with payment dates, the cancellation window and what happens to unused sessions. The single next step. And a date after which you’ll stop chasing. One screen on a phone. The reflection at the top is the part that does the work, and the part most follow-ups skip in favor of a recap of the call.
How soon should I send it?
The same day, or before 10:00 the next morning if the call ran late. The person who is going to say yes is the one who existed during the conversation, and that version fades over the next couple of days. You also still have their exact words while the day is still the same day, and their own words do work that any paraphrase of yours would lose. If today is too full to write it properly, send four lines saying it arrives tomorrow, then keep that promise.
Should I put the price in the follow-up email or wait until they ask?
Put it in, in full, with the payment schedule. Withholding it buys one extra email and spends the buyer’s goodwill to get it, because the client now has to ask about money, and money is the thing they were already uncomfortable about. Restate the number even if you said it on the call. A written figure can be acted on, forwarded to a spouse, and found again in a week. A figure spoken aloud goes nowhere.
How many times should I follow up if they do not reply?
Two more contacts, then stop. The first around five business days later, short, adding one fact rather than asking whether they saw the last email. The second a week or so after that, saying you’re taking it off your list and naming how to reopen it. The closing message often gets the reply, because it lifts the pressure that was holding one back. Escalating frequency as hope drops is the one pattern that reliably costs you the referral as well as the sale.
What do I write when I am not the right coach for them?
Say so, quickly, in three sentences: what you heard, that you’re the wrong person for it, and why in one non-wounding line. Then offer a name if you have one. If there’s a referral fee, disclose it in the same email. The ICF Code asks the coach to disclose the potential receipt of compensation and other benefits for referring clients to third parties, and a referral you’d rather keep the fee quiet about is a sale.
Can I add someone to my mailing list after a discovery call?
Ask first. A single reply to a conversation they started is one thing. A newsletter or an automated sequence is commercial email under the CAN-SPAM Act, which has no exception for business-to-business messages. Those need a valid physical postal address, a clear opt-out and that opt-out honored within 10 business days. The FTC’s own guide puts the penalty at up to $53,088 per email, as checked on September 6, 2026. Ask on the call, or ask in the follow-up, and take the answer.
Should I include a testimonial or a client result?
Better to leave it out. The FTC’s Endorsement Guides treat a client quote in a marketing email as an endorsement, and an endorsement about a key attribute is read as representing what clients will generally achieve. Where substantiation that it is representative is missing, the rule asks you to disclose the generally expected performance instead, which almost no solo practice can do. Describe your experience factually and describe the process. Leave outcome claims out.
They said yes on the call and then went quiet. What now?
Treat it as an ordinary open loop rather than a change of heart. Send the proposal if it’s still unsent, then the one short chase, then the closing message, on the same timetable as any other. The most common cause is that something else in their week fell over and the delay became embarrassing. Your closing message solves that by making it easy to come back and skip the explanation.
Does any of this change if the discovery call was in person?
Only in one respect. A discovery meeting held in person tends to end with more agreed out loud and less of it written down. So the reflection paragraph does more work, and the price paragraph is more likely to be the first time the number has been written anywhere. Send it the same day for the same reason, and be more careful than usual to restate anything you shook hands on.
The short version
Write it the same day. Open with what they said, in their words, because that’s the paragraph that proves the half hour was about them. Then the shape of what you’d do, and why that shape. Then the price in full, with dates, the cancellation window and what happens to unused sessions. Then one next step, and one date after which you’ll stop.
Chase twice and close the loop, and let the closing message be a real one. Keep outcome claims out of it, keep your credentials accurate to the letter, and if a referral carries a fee, say so in the sentence where you make it. Persuasion sits outside all of this. The persuading finished when the call did, and what’s left is making the decision easy to make and easy to say no to.
What you’re coaching moves the emphasis. A coaching practice selling six month engagements is asking for a decision large enough that a second reader is usually involved, which makes the forwardable version of the email part of the design. Short packages need the price and the link and little else. Employer-sponsored work is a confidentiality question before it’s a proposal. The other trades this was built for sit somewhere between, and the constant across all of them is that the follow-up is the only part of the sale the buyer gets to read twice.
