Win back lapsed free trials, on autopilot

Trials that expire without upgrading are the cheapest revenue you are ignoring. They already know your product. This agentic workflow re-engages them with proof and a reason to come back, while you sleep.

The workflow

How does the trial win-back workflow run?

The trial win-back workflow runs once a day: a trigger finds trials that lapsed without converting. The agent enriches each one with how much they actually used the product and who they are, scores their likelihood to come back, and drafts a personalized win-back referencing what they did in the trial. You approve in one click. The agent sends and books the call. Nothing risky goes out without your nod.

Which lapsed trials are worth winning back?

Win back the trials that showed real intent and then stalled, not every expired account. Usage is the best signal you have, so score on it. An example rubric you can adjust:

• +30 if they logged in on three or more separate days.
• +30 if they finished the main setup step, such as connecting a data source or importing contacts.
• +20 if they invited a teammate.
• +20 if the company matches your ideal customer by size and industry.

Send the win-back to anyone at 50 or above. Leave out trials that never came back after day one: those people did not stall, they never started, and an onboarding fix will do more for them than a win-back email. Also leave out disposable email addresses, competitors, and anyone who answered a cancellation survey with "not a fit."

When should each message go out?

Send the first message within a day of the trial expiring, while the product is still fresh in their mind. A sample schedule that matches the copy below:

• Day 1 after expiry: the win-back email, naming what they did in the trial.
• Day 2: the LinkedIn DM, only if you are already connected or they engaged with your posts.
• Day 4: the last-note nudge with the short clip.
• After day 4: stop. Tag the account and leave it alone until you ship something that fixes the reason they left.

Three touches in four days is enough. A fourth message mostly raises the unsubscribe rate.

The copy to steal

Three message variants the agent drafts from. Copy any of them and tune to your product.

How do you know if the win-back is working?

Track four numbers each month: reply rate, reactivation rate, revenue recovered, and unsubscribe rate. The arithmetic is simple. Say 40 trials lapse in a month and your scoring keeps 15 of them. If 2 of those 15 come back on a $99 monthly plan, that is $198 in new monthly revenue, or about $2,400 over a year, from one month of lapsed trials. Run the same math on your own price and volume before you build anything, so you know what a good month looks like.

If the unsubscribe rate climbs above the reply rate, the copy is too pushy or the scoring is too loose. Tighten the threshold before you touch the copy.

Edge cases to handle before you turn it on

• They upgraded yesterday. Check the account status right before each send, not only when the list is built.
• Several people from one company trialed. Write to the person who used the product most, once.
• The trial was extended. Treat the new end date as the trigger, or you will send a win-back to an active user.
• No usage data. Without usage, the personal line in the email becomes a guess. Send a plain check-in instead of pretending to know what they did.
• Consent. Make sure your trial sign-up terms cover follow-up email, and honor every unsubscribe at once.

What should you change if nobody replies?

Change one thing at a time, in this order, and give each change two weeks. First the subject line, since an unopened email cannot get a reply. Then the offer: some people want the 15-minute call, others only want the setup link or the clip, so try leading with the low-effort option. Then the timing, for example moving the first email from day 1 to the last day of the trial. If none of that moves the reply rate, the problem is likely the product gap that made them leave, and that is worth a conversation with your team, not another email.

When should you skip this workflow?

Skip the automated win-back if fewer than about ten trials lapse a month: write those notes by hand, they will be better. Skip it too if most trials never get past setup, because that is an onboarding problem and no follow-up email fixes it.
