Short answer
A good sales follow-up email is matched to what happened last: an unanswered cold email, a call, a meeting, a proposal, an event or a deal that went quiet. It names that context in the first line, adds one new thing (a fact, an answer, an example or a smaller option), asks one easy question and stays under about 120 words. Reply in the same thread where one exists, and stop when they say no or opt out.
- Pick the follow-up by what happened last: a meeting recap and a no-reply nudge are different emails.
- Every follow-up adds one new thing: a fact, an answer, an example or a smaller ask.
- Replace "just checking in" with the reason you're writing, in the first line and the subject.
- Wait two to three business days before a first nudge, then leave longer gaps.
- CAN-SPAM makes no exception for B2B email: honor opt-outs within 10 business days and keep subject lines accurate.

This page is for SDRs, account executives, founders and account managers who need to write the next email in a deal and aren't sure which kind it should be. It maps the ten follow-up situations you'll meet most often to one template each, with when to send it and what to add. Where a situation has its own full set of templates, the table links to it.
Find your situation
A follow-up is defined by what happened last. Find the row, use the template below, and go to the full set if you need more variations.
| What happened last | When to send | What the email adds | Full set |
|---|---|---|---|
| You sent a cold email and got no reply | 2 to 3 business days later, then wider gaps | A second fact about their company | Cold email follow-ups |
| You cold called and they said "email me" | Within the hour | The one thing they told you, plus a time | After a cold call |
| You had a discovery call or demo | The same day | Their words, next steps with owners and dates | After a sales call |
| You met in person or on video | The same day or next morning | What you agreed and the one item you promised | After a meeting |
| You sent a proposal | 2 to 3 business days later, or before their decision date | The answer to the question the decision maker will ask | After a proposal |
| A live deal went quiet | A few days after a promised date passes | A yes-or-no question | After no response |
| You met at an event | Within 2 business days | The answer or resource you promised at the booth | Below |
| They downloaded something or asked a question | The same day | A question about why, and one useful answer | Below |
| You last spoke months ago | When something has changed, or on the date they gave | What's new since they said "not now" | Re-engagement emails |
| Three or four follow-ups went unanswered | After the last one | A clear, polite stop | Breakup emails |
Two situations have no row because they need a different email, not a follow-up. When a colleague or customer introduces you, use a referral email. When a prospect says no, thank them, ask in one line what decided it, and stop.
The format every follow-up shares
Whatever the situation, a sales follow-up email has the same five parts, in this order:
- A subject line that says what's inside. "Notes from Tuesday's call" or "Your question about restore times", never "Following up".
- The context in the first line. What happened last and when: the call, the proposal, the booth, last week's email. The reader shouldn't have to scroll to remember you.
- One new thing. A second fact about their company, the answer you promised, a short example from a similar customer, or a smaller option. If you have nothing new, you're not ready to send.
- One question that's easy to answer. Ideally yes or no, or a choice between two times. "Let me know your thoughts" isn't a question.
- A plain sign-off. Name, role, phone. On prospecting email, your postal address and a way to opt out (see the rules below).
Keep nudges under about 120 words and recaps under about 200, so the whole email fits on a phone screen.

Fill every bracket with something true and specific. If you can't fill one, cut the line rather than inventing it.
(Reply in the same thread) Hi [first name], One more detail since my last note: [a second fact about their company, e.g. you're hiring a systems administrator to cover both plants]. That usually means [the problem it points to]. [A similar company] handled it by [what they did]. Is [problem] on your list this quarter, or should I leave it? [Your name]
Subject: [The topic you named on the call] Hi [first name], Thanks for picking up today. As promised, the short version. You said [what they told you, in their words]. [One sentence on what you'd do about it, or the number you promised.] Worth 15 minutes on [day] at [time] to see if it fits [company]? [Your name] [Phone]
Subject: [Topic]: notes from [day]'s call Hi [first name], Thanks for the time today. Here's what I heard: - [Their problem, in their words] - [Why it matters now: the deadline or trigger they mentioned] - [How they'll decide: who's involved and by when] Next steps: - Me: [what you'll send or do] by [date] - You: [what they agreed to do] by [date] - Together: [next meeting, day and time], invite sent Did I get anything wrong? [Your name]
Subject: [Day] at [site]: the three things we agreed Hi [first name], Thanks for showing me around [site] on [day]. Seeing [specific thing you saw] made [the problem] much clearer. We agreed: 1. [Agreement or next step] ([owner], [date]) 2. [Agreement or next step] ([owner], [date]) 3. [Agreement or next step] ([owner], [date]) As promised, [the one item] is attached. Does [date] still work for [next step]? [Your name]
Subject: [Company] proposal: the question [decision maker's role] will ask Hi [first name], While you review the proposal, one thing [the CFO / the owner] will probably ask is [the question, e.g. "what does this replace, and what does it save?"]. The short answer: [one or two lines with the number and its assumption]. Is anything in the proposal unclear, or is it waiting on [the decision step they described]? [Your name]
(Reply in the same thread) Hi [first name], Quick yes or no: is [project] still happening this [quarter / year]? If it's moved, tell me roughly when and I'll check back then rather than filling your inbox. [Your name]
Subject: [Event]: [the topic you discussed] Hi [first name], Good to meet you at [booth / session] on [day]. You mentioned [the specific problem they raised]. [The useful thing you promised: an answer, a one-page checklist, a figure.] If it's worth a proper look, would [day] at [time] work for 20 minutes? [Your name]
Subject: Your question about [topic] Hi [first name], You [downloaded our guide to X / asked about Y] on [day]. People usually do that when [the situation it suggests]. Is that what's happening at [company], or were you researching? Either way, here's [the single most useful answer or resource]. [Your name]
Subject: [Topic], [month] update Hi [first name], When we spoke in [month], you said the timing depended on [their reason, in their words]. Since then, [what's changed: their news, or something new you can show]. Is it worth picking up again, or is it still not the right time? [Your name]
Subject: Closing the loop on [topic] Hi [first name], I haven't heard back, so I'll assume [topic] isn't a priority right now and stop emailing about it. If that changes, reply to this thread anytime and I'll pick it up from here. Thanks, [Your name]
How many follow-ups, and how far apart
The first follow-up matters most. In a 2019 analysis of 12 million outreach emails sent through the Pitchbox platform, Backlinko found that one additional follow-up raised replies by 65.8%, and that three or more messages gave the best overall response rate. Those were mostly outreach emails, not B2B sales emails, so treat the direction as useful and the exact figure as someone else's result.
A pattern that works for prospecting: a first nudge two to three business days after the first email, then gaps of four to seven days, with one change of channel (a call or a LinkedIn message) and a last email after three or four attempts. In a live deal, follow up on the dates the prospect gave you, not on a fixed cadence. The guide to how many follow-up emails to send works through the trade-offs, and the sales follow-up statistics collect the sourced figures.
Subject lines that say why you're writing
| Instead of | Try | Why it works |
|---|---|---|
| Following up | Notes from Tuesday's call | Names what's inside |
| Just checking in | Is the second plant still opening in March? | They can answer from the subject line |
| Any update? | [Company] proposal: the cost question | Tells them which document and which issue |
| Re: (on a new email) | Your question about restore times | Honest: a fake "Re:" can mislead |
| Last chance! | Closing the loop on offsite backup | Low pressure and accurate |
Worked example: one deal, five follow-ups
Illustrative example. The companies, people and figures are fictional, to show the method.
The seller: Ellis, an account executive at Coldharbor Backup (coldharbor.example), a cloud backup provider for mid-sized companies. The prospect: Renata, IT manager at Tillman Contract Molding (tillmanmolding.example), a contract manufacturer with 180 employees that opened a second plant in August.
| Day | What happened | Follow-up used | What it added |
|---|---|---|---|
| 1 | Cold email about the second plant | (first email) | |
| 4 | No reply | Cold email follow-up | Tillman is hiring a systems administrator to "own backup for both sites" |
| 6 | Renata replies and takes a call | Discovery recap, same day | Her words: "our last restore test took 26 hours" |
| 13 | Proposal sent | ||
| 16 | No reply | Proposal follow-up | The cost comparison her CFO will ask for |
| 24 | Still quiet | Yes-or-no question | "Is this still happening before year end?" |
On the call, Renata said Tillman protects about 22 TB across both plants with tape and an offsite courier. The courier costs $350 a month, and a technician spends about six hours a week on tapes at $40 an hour. Coldharbor's quote is $45 per TB per month. The proposal follow-up on day 16 answered the question Renata said her CFO always asks first:
| Current tape setup | Coldharbor | |
|---|---|---|
| Courier | $350 × 12 = $4,200 | $0 |
| Technician time | 6 h × 52 weeks × $40 = $12,480 | About 1 h a week: 52 × $40 = $2,080 |
| Service | $0 | 22 TB × $45 × 12 = $11,880 |
| Total a year | $16,680 | $13,960 |
That's $2,720 a year less, before counting the restore time Renata cared about most. The email:
Subject: Tillman proposal: the cost question
Hi Renata,
While you review the proposal, the first thing Dev will probably ask is what it replaces and what it costs against that. Using your figures: tapes, the courier and about six hours a week of technician time come to $16,680 a year. Coldharbor for 22 TB is $11,880, plus about an hour a week of checking, so $13,960 in total. The bigger change is the restore test: our target for your ERP server is under four hours, against the 26 you measured.
Is anything in the proposal unclear, or is it waiting on Dev's budget review?
Ellis
Renata answered the day 24 email: the budget review had moved to November, so Ellis sent nothing until then. Each follow-up worked because it carried something new: a fact, her own words, the CFO's numbers, then an easy question. Finding the day 4 fact is the slow part at volume; Bebop researches each account and writes a playbook with what's happening at the company and who's involved, which gives every follow-up something real to add.
The rules that apply to follow-ups
This is general information, not legal advice.
- B2B email is covered. The FTC's CAN-SPAM compliance guide says plainly that "the law makes no exception for business-to-business email". A follow-up whose main purpose is to sell is a commercial message.
- Subject lines must be accurate. The guide says "the subject line must accurately reflect the content of the message", and the Act (15 U.S.C. 7704) bars subject headings likely to mislead a reasonable recipient. A "Re:" on an email that isn't a reply is the classic risk.
- Honor opt-outs within 10 business days. Every commercial email needs a working way to opt out, kept working for at least 30 days after you send, and the request must be honored within 10 business days. If someone replies "stop", that counts. Take them out of every sequence, not just the current one.
- Include a postal address. Commercial email must carry a valid physical postal address, and the FTC's guide lists penalties of up to $53,088 for each email in violation.
Mistakes to avoid
- "Just checking in" or "bumping this to the top of your inbox". Both describe your action, not their benefit, and give the reader nothing to reply to.
- Resending the same email. If the first one didn't work, the same words won't either.
- Guilt. "I've emailed you three times" makes the reader feel bad about you, not about the problem.
- Three questions in one email. Ask one. The reader answers the easiest question or none.
- Following up after a no. A clear no or an opt-out ends the sequence. Respecting it is how you earn a reply next year.
Checklist before you send
- You know which situation this is, and you used the matching email.
- The first line says what happened last and when.
- The email adds one thing the prospect didn't have before.
- The subject line describes the content and isn't a fake reply.
- There's one question, and it's easy to answer.
- Prospecting email includes your postal address and a way to opt out.
- You've checked the prospect hasn't already replied, opted out or been contacted by a colleague.
Next step: if your follow-ups go out but replies don't come back, the problem may be the first email. Rebuild it with the cold email follow-up templates, which add one new fact at every step.

Questions people ask
How do you write a sales follow-up email?
Start with the situation: what happened last and when. Then add one new thing the prospect didn't have before, such as a fact about their company, an answer you promised or a short example from a similar customer. End with one easy question, ideally yes or no or a choice of two times. Keep it under about 120 words, give it a subject line that describes the content and reply in the existing thread where there is one.
How long should you wait before sending a follow-up email?
It depends on what happened last. After a call or meeting, send the recap the same day. After an unanswered cold email, wait two to three business days, then leave wider gaps of four to seven days. After a proposal, follow up two to three business days later or just before the decision date the prospect gave you. In a live deal, follow the dates the prospect set, not a fixed schedule.
What do you say in a follow-up email when you haven't heard back?
Reply in the same thread and ask a short yes-or-no question about the project, such as "Is the rollout still happening this quarter?" Offer to check back on a date they choose if it has moved. Add one new reason to reply where you can, like a deadline or a fact. Don't guilt them or resend your last email. If two or three of these go unanswered, send a polite last email and stop.
How many follow-up emails should you send?
For prospecting, three or four follow-ups over two to three weeks is a common pattern, with one change of channel, then a last email. A 2019 Backlinko analysis of 12 million outreach emails found one extra follow-up raised replies by 65.8% and three or more messages did best overall, though those weren't all sales emails. In a live deal, follow up on agreed dates. Stop at any no or opt-out.
What is a good subject line for a sales follow-up email?
One that tells the reader what's inside: "Notes from Tuesday's call", "Tillman proposal: the cost question" or "Is the March launch still on?" Avoid "Following up", "Checking in" and "Any update?", which describe your action rather than the content. Never add "Re:" to an email that isn't a reply: US law requires subject lines on commercial email to reflect the content accurately.
