How to write a win-back email

A few people bought, tried or hired you once, then went quiet, and with only a handful of customers, each one is a big share of your business and costs far more to replace than to win back. To write a win-back email that works at this size, send each quiet person a short personal note that asks why they stopped, then fix what they tell you. A "We miss you, here's 20% off" email brings back the few who would have come back anyway, and teaches you nothing.

Do these three things

About 2 hours today, then 20 to 40 minutes a day and 20 minutes on Sunday. Read every reason the day it arrives, and judge the email itself after 50 people have had all four emails.

1. 1Today: list every customer, trial user and past client who has gone quiet, and send each one a short personal email that asks why they stopped. AI drafts it; you add one true line about what they bought.
2. 2Every day: email each new person the day they go quiet, send every follow-up that is due (up to 3: day 4, day 10 and day 21), and answer every reply the same day.
3. 3Every Sunday: count replies, the reasons people gave and who came back. Fix the most common reason before next week's emails go out, so fewer people leave in the first place.

1. List everyone who has gone quiet, and decide when quiet starts for you

Make one sheet of every person who bought, tried or hired you and has gone longer than your normal gap without coming back. That gap is your "quiet line". Everyone past it gets a win-back email.

Pick your quiet line with the rule for your business:

If you run a D2C store: with no repeat buyers yet, use how long one order lasts, plus 2 weeks. Once 10 or more people have ordered twice, use the gap by which most of them (75 to 85%) had reordered. Klaviyo's help page says to wait a little longer than your average gap between orders. Someone who left items in the cart without paying is an abandoned cart, not a win-back.

If you run a SaaS: a free trial that ended 3 days ago without paying, or a paid user who cancelled yesterday. Someone who signed up and never used it is an activation problem, not a win-back. A paid user who leaves counts toward your churn rate.

If you run a B2B business: a client who has gone 1.5 times their usual reorder gap without ordering. Also a quote that got no answer, 60 days after your last follow-up on the proposal.

If you run an agency: a client whose project ended or whose retainer stopped 60 days ago. Keeping a client who is still paying is a different job: reducing client churn.

Then list everyone past the line. Give each person one row: name, email, what they bought or used, the date, their quiet date, and a status column. On Shopify, open Customers, then Segments, then Create segment, and type last_order_date < -60d (change 60 to your quiet line). Click Run query, then Save segment. For SaaS, Stripe shows cancelled plans under Billing, then Subscriptions.

Take three kinds of people out before you send anything:

• Anyone with an open problem: a refund, a late delivery, a complaint. Fix it first. A sales email in the middle of a refund makes people angry.
• Anyone who unsubscribed or asked you to stop.
• Anyone whose email bounced. Mail to a dead address reaches nobody and hurts your email deliverability.

If your list has fewer than 20 names, add everyone who ever bought once, started a trial or asked for a quote, however long ago. They are all part of your email list, and at this size each one matters.

• Tool: Google Sheets. Shopify's segments or Stripe's subscription list if you use them. All free. A CRM can wait until the sheet gets slow.
• Time: 45 minutes.
• You will have: one sheet with every quiet person, their quiet date and what they bought.
• It worked if: everyone past the line is in the sheet, and nobody with an open problem or an unsubscribe is.
• Common mistake: using 60 days for every product. If one order lasts 90 days, a customer is not quiet at day 60. They are just not out yet.

2. Write a win-back email that asks why they stopped

A good win-back email is short, plain and from you: one true line about what they bought, one question about why they stopped, and one reason to come back. Write it once, in under 100 words, with no discount.

Write it the way you would write to one person, because you are. Since July 2025, Gmail has a "Manage subscriptions" page that lists every sender and lets people unsubscribe in one click. An email that looks like a mass newsletter is easy to leave. A short note from a person with a real question is easy to answer.

Use these parts, in this order:

1. The subject line looks like a personal email: their first name and the product, in lower case, under 6 words.
2. One true line about what they bought or used, and when.
3. One question: "What made you stop?" Give 3 short answers they can reply with in one word. A one-word reply is easy, and every reply tells you something.
4. One reason to come back: what changed, or how you can help. Not money off. Money off waits for step 3.
5. Your name, your postal address and a "reply no" line. The law needs these (step 4).

What the reason to come back is changes by business:

If you run a D2C store: the repeat order made easy: a link that puts their last order straight in the cart, or a tip on getting the most from what they bought.

If you run a SaaS: offer to extend the trial by 14 days and set it up with them on a 15-minute call. Or name the one feature you shipped since they left.

If you run a B2B business: a reminder of the lead time before their busy season, and an offer to send a new sample or a quick quote for their next order.

If you run an agency: one specific thing you noticed about their marketing since the work ended, and an offer of a free 30-minute review. Many past clients come back as monthly retainers.

Subject: [first name], your [product]Hi [first name],You [bought / tried / hired us for] [what they bought] in [month]. [One true line: how they used it, what they said, or what it was for.]I noticed you haven't [ordered / logged in / been in touch] since, and I'd like to know why. What made you stop? A one-word reply is perfect:
Price
Not needed yet
Something else (tell me what)
[One reason to come back: what changed, or how you can help.][Your first name]
[Your business, postal address]
Not for you? Reply "no" and I won't write again.

Use ChatGPT or Claude to write the one true line for each person. Paste in their first name, what they bought and when, plus anything they told you. Leave out addresses and payment details. Check every line is true before it goes in the email.

• Tool: a Google Doc for the email, and ChatGPT or Claude to draft the personal line.
• Time: 30 minutes to write the email once.
• You will have: one win-back email, ready to copy.
• It worked if: it is under 100 words, a friend can answer it in 10 seconds, and it has no discount.
• Common mistake: sending a designed newsletter with a banner and four products. It looks like every other sale email, and it asks nothing you can learn from.

3. Write three follow-ups, and save any discount for the last one

Most people will not answer the first email, so write three short follow-ups now: day 4, day 10 and day 21. Each one goes in the same email thread and adds one new thing. The last one says it is the last.

Each follow-up has one job. Follow-up 1 is a short nudge. Follow-up 2 adds one new thing: a short customer quote, a change you made, or a tip. Follow-up 3 says you will stop writing, and it is the only place an offer may go. Follow-ups are the same as for cold email: short, new each time, and never "just checking in".

The discount rule: do not offer money off in the first three emails. Put an offer in follow-up 3 only if price is the most common reason in the replies so far. If it is not, offer help instead. A discount sent to everyone trains customers to wait for the next one, and it costs you money on people who would have come back anyway. If price really is the reason, check your pricing too, and whether people left after you raised your prices.

If you run a D2C store: if you do make an offer, try free shipping or a free sample with the next order before any percentage off.

If you run a SaaS: if price is the reason, offer a smaller plan or a monthly option before a discount. See if your pricing has a step that fits them.

Follow-up 1 (day 4):
Hi [first name], did this get buried? A one-word reply is all I need.Follow-up 2 (day 10):
Hi [first name], one more thing: [one new thing: a change you made, a short customer quote, or a tip]. Still keen to hear what made you stop.Follow-up 3 (day 21):
Hi [first name], this is my last email about this. If [the reason most people gave] was the problem, [the help or the offer, following the discount rule]. If not, no hard feelings, and thank you for trying [product].

• Tool: the same Google Doc.
• Time: 30 minutes.
• You will have: three follow-ups, ready to copy.
• It worked if: each fits on one phone screen, follow-up 2 says something new, and follow-up 3 says it is the last.
• Common mistake: a "discount ladder" that starts at 10% off in email 1 and rises each time. People learn to wait for the biggest number.

4. Send each win-back email by hand, the day the person goes quiet

Today, send the win-back email to everyone on your list. From tomorrow, check the sheet every day and email each person on the day they pass the quiet line. Send each follow-up on the day it is due.

Paste 10 rows at a time into ChatGPT or Claude with the template, and ask for one email per person. Read each draft, check the personal line is true, and send it from your normal email address, one at a time. That is about 3 minutes an email. Do not use a second domain you set up for cold email: these people know you by your main address. Send follow-ups as replies in the same thread, so people see the whole story. Write the date in the sheet each time.

Keep everyone who wants out, out:

• Gmail rules: every sender needs SPF or DKIM, two settings that prove an email really comes from your domain. Ask your email host to confirm one is on. Keep spam reports below 0.3%. Since November 2025, Gmail has been rejecting more mail that breaks these rules. Google also asks senders to act on an unsubscribe within 48 hours.
• US law: the CAN-SPAM Act covers emails to former customers too. Every email needs your postal address and a way to say no. Act on a "no" within 10 business days.
• UK law: you may email people who bought, or talked about buying, something similar from you, if you gave them a way to opt out when you took their email and you give one in every email. The UK regulator is reviewing this guidance after a 2025 law change, and it does not say whether free trials count. If your buyers are in the UK or the EU, check the local rules first.

When to stop doing it by hand: while fewer than 50 new people go quiet each month, send every email yourself. You learn more, and the replies come to you. Over 50 a month, switch on the automatic version:

If you run a D2C store: in Shopify, open Apps, then Messaging, then Automations. Click Create automation and choose "Win back customers". It starts when a customer joins a segment, so use your quiet-line segment from step 1. Make the email plain and sign it with your name, so it still reads like a note from you. Shopify Messaging, formerly Shopify Email, sends your first 10,000 emails a month free. If you already use Klaviyo, build it as a Klaviyo flow instead.

If you run a SaaS, B2B business or agency: keep it in Gmail until it takes more than an hour a day. Then put the four emails into the email tool you already use for onboarding emails or lead nurturing, sent from your own address.

• Tool: Gmail or your normal work email, your sheet, and ChatGPT or Claude to draft. Shopify Messaging once you pass 50 a month.
• Time: about 1 hour today for 20 people, then about 20 minutes a day.
• You will have: every quiet person emailed on the right day, with each follow-up logged.
• It worked if: at the end of each day, nobody past the quiet line is without an email, and no follow-up is overdue.
• Common mistake: sending from a "no-reply" address. The whole point is the reply. The other mistake is sending all the emails at once from a bulk tool on day one, which looks like spam to people and to Gmail.

5. Answer every reply the same day and fix what they tell you

Every reply is the most useful thing a win-back email brings you, so answer each one the same day and stop their follow-ups. Then act on the reason they gave.

Write the reason in the sheet, in their words. Then answer by kind:

• Price: thank them, say in one line what they get for the price, and offer a smaller size or plan if you have one. Count it for Sunday.
• A problem with the product or service: say sorry, fix it or refund it, and tell them what you changed. This is the reply that can bring someone back, and it improves things for everyone else. Ask if you can use their words later as feedback from your first users. If they write a long answer, offer a 15-minute call and run it like a customer interview.
• Not needed yet: ask when they think they will need it, and put that date in the sheet.
• Forgot: send the direct link to reorder, log in or book a call.
• No: mark it in the sheet and never email them again.

If someone comes back happy, ask them for a short testimonial a week later, or, for a B2B client or agency client, a short case study. People who came back after you fixed something often say the most useful things about you. Once they have ordered twice, ask if they know someone else who would like it: that is how a referral program starts.

Thank you, [first name], that really helps.[One line on the reason: what you changed, what you can do, or a question about when.][If it fits: the direct link, or the offer of a call.][Your first name]

• Tool: Gmail and your sheet.
• Time: 5 to 10 minutes a reply.
• You will have: an answer sent to every reply, and every reason written down in the person's own words.
• It worked if: every reply got an answer within 1 day, and nobody who answered got another follow-up.
• Common mistake: asking why, then not answering. In April 2025, a user posted on Hacker News about getting a "why did you cancel?" email from a software founder, replied with five reasons, and "never got a response". A question you do not follow up is worse than no email.

6. Count replies, reasons and comebacks every Sunday

Every Sunday, write one row in your sheet: how many people you emailed, how many replied, which reasons they gave and who came back. Then fix the most common reason before next week's emails go out.

Count people by name: who replied, who ordered or renewed again, who said no. Do not count opens. Klaviyo's own help page warns that Apple Mail Privacy Protection can make open rates look higher than they are: an email can count as opened when nobody read it. A reply or an order cannot be faked.

You do not need a test group that gets no email. In September 2026, a Shopify Community reply worked out that you need about 700 customers in each group to measure a lift like that. At your size, the names in your sheet are the answer.

Week | Emailed | Replied | Price | Not needed yet | A problem | Forgot | Said no | Came back (names)

Then use these rules:

• As soon as one reason shows up in 3 or more replies, fix it before you send more. "Not needed yet" means your quiet line is too early, so move it later. "Price" means follow-up 3 may carry an offer. "A problem" means fix the product or the delivery.
• After 50 people have had all four emails, if fewer than 1 in 10 replied, rewrite the first line and the question in the win-back email. Make the line more about them and the question easier to answer.
• For each person who came back, note which email they answered. If most answered follow-up 2, move its "new thing" into the first email.

A win-back email only brings back people who already left. If more than half the reasons point to one problem, fix the product, the onboarding or the delivery, so the next customers stay longer. If past agency clients say they could not see what the work did, send current clients a monthly report. Once a month, add the totals to your marketing review.

• Tool: Google Sheets.
• Time: 20 minutes each Sunday.
• You will have: one row a week, and the reasons people leave, in order.
• It worked if: you can name each person who came back and which email they answered.
• Common mistake: changing the email after 5 people. Read every reason as it comes in, but judge the email itself after 50.
