The templates
Each one copies with its subject line. Change the parts in brackets, and quote the customer’s own words where the template asks for their reason: it is the line that proves a person read what they wrote.
Subject: The [problem] you told me about is fixed
Subject: [Feature] is in [Product] now
Subject: One question about [Product]
Subject: An offer to come back to [Product], until [date]
Subject: The last email from me about [Product]
Subject: Your [Product] year ended on [date]
Win-back subject lines
Lead with the news, not with “we miss you”. Someone who cancelled will open an email about the thing they cancelled over, and archive one that reads like a campaign.
- The [problem] you told me about is fixed
- [Feature] is in [Product] now
- One question about [Product]
- Your [Product] year ended on [date]
- The last email from me about [Product]
What makes a win-back email worth opening
- Only write when something changed. A fix, a feature, a new plan, a lower price. With no news, the email asks them to reconsider a decision nothing has given them a reason to change.
- Use their reason, in their words. “You told me sync kept dropping files” is a sentence no automated campaign can write, and it is why this email gets read.
- One email, maybe two. Not a sequence of guilt. If they do not come back after the email about the fix, the next one will not change that.
- Say what is still there. Their data, their settings, their old price. “Everything is where you left it” makes coming back a click instead of a project.
- Keep your promises. If the email says the offer ends on a date, it ends. If it says it is the last email, it is.
- Do not ask twice. If your cancellation confirmation already asked why they left, the question-only email is redundant. Send it only to people who were never asked.
And what not to write: “We miss you!”, a sad face in the subject line, a discount on an unchanged product, or anything suggesting they made a mistake by leaving.
Unsubscribes and marketing consent
A win-back email is usually a marketing email, even written by hand, because its purpose is to sell the product again. That brings the marketing rules in. In the US, CAN-SPAM requires commercial email to include a way to opt out, and opt-outs to be honoured. In the UK and much of the EU, emailing a former customer about your own similar product can fall under an existing-customer exception, as long as they were offered a way to opt out when you collected their address and in every message since; otherwise you generally need their consent. The details differ by country and change over time, so treat this as a prompt to check, not as legal advice.
The habits that keep you on the right side almost everywhere: never email someone who unsubscribed or asked you to stop, put an easy way to opt out in every win-back email, and delete data you promised to delete.
The win-back you can only send if you remember
The best email on this page depends on a fact that is easy to lose: that this customer left because of that problem. They told you in March. The fix shipped in July. By July their email is in the archive next to hundreds of conversations that really did end, and nothing connects the fix to the person who is owed the news.
That is the gap Moorline is built around: the work is not done, or the customer has not been told. A conversation stays on your list until both are true, so when someone cancels over a bug you have not fixed yet, their thread is still there when the fix ships, and the win-back is a reply in their own thread rather than a campaign. With Stripe connected, their plan shows beside it, read-only, so you can see whether they have already come back on their own. The words for that moment are the same as the issue resolved email templates, sent to someone who has already left.
Questions people ask
What is a win-back email?
An email to a customer who cancelled or did not renew, inviting them back. For a subscription software product, the ones that work are about something specific: the problem they left over is fixed, the feature they asked for shipped, or the price that put them off has changed. Without news, a win-back email is just a reminder that they left.
When should I send a win-back email?
When something has changed that matters to that customer, not on a timer. If nothing has changed, the one email worth sending is a single question about why they left, shortly after they cancel, and only if your cancellation confirmation did not already ask it.
How many win-back emails should I send?
One, two at most, then stop. A sequence of "we miss you", "are you sure" and "last chance" emails spends whatever goodwill the customer left with, and it is the kind of mail people mark as spam. If you say an email is the last one, make sure it is.
Should a win-back email include a discount?
Only alongside a real change, and with a real end date. A discount on the same product they left asks them to pay less for something that did not work for them, and tells everyone still paying that the price was negotiable. The exception is a customer who left over price: then the lower price is the change, and the email can say so plainly.
Is it legal to email customers who cancelled?
Often, but marketing rules usually apply, because the purpose is to sell the product again. That generally means a working way to opt out in every message and honouring it, and in the UK and EU it can also depend on consent or an existing-customer exception. Rules differ by country and this is not legal advice; check the ones that apply to you, and never email someone who unsubscribed.
