Re-engagement Sequence
A re-engagement sequence is a set of automated messages aimed at reviving contacts who have gone inactive, prompting them to interact again before they fully disengage.
Key takeaways
- Enrolment is triggered by an inactivity window, not by anything the contact did.
- Any open, click or reply should remove the contact from the sequence immediately.
- Offering a frequency change retains more contacts than an unsubscribe-or-nothing choice.
- Cap attempts at three or four messages to limit complaint and bounce exposure.
- Non-responders should be suppressed, not left in the regular sending pool.
In depth
A re-engagement sequence starts from an inactivity rule rather than an action. You define a lookback window, such as no open, click, login or purchase in ninety days, and the platform enrols every contact who crosses that line. Messages then run in a fixed order, because there is no behavior to branch on until the contact responds. The first open, click or reply pulls them out and returns them to normal segments, while continued silence carries them to the final message and then to suppression.
Recovery depends mostly on how the window is drawn. A short window catches people who were merely on holiday and treats them as lapsed; a long one waits until the address has gone stale and the recipient no longer recognises the sender. The other lever is send volume. Every extra attempt to an unresponsive address adds complaint and bounce risk, so most programmes cap the sequence at three or four messages and accept that the rest of the segment is genuinely gone.
A working sequence usually has three moves: a plain-text question that breaks the template pattern, an offer of a preference or frequency change instead of a full exit, and a closing note stating that this is the last email unless they act. Scorecard results from an earlier quiz decide who gets which version, since a contact who once landed in the top score tier is worth a personal message from a rep, while a low-fit contact gets one automated attempt.
Inactivity is not the same as disinterest, and the signal you measure may be broken rather than the relationship. Image blocking hides opens, a mailbox that already files you under promotions produces silence that is really a placement problem, and a business address left behind after a job change will never respond. Running the sequence also cannot repair a list built from purchased or scraped addresses, where the contacts never opted in and reactivation was never possible.
Example in practice
How to measure it
The primary number is reactivation rate: contacts who took a qualifying action during the sequence divided by contacts enrolled. Define the qualifying action before you launch, because counting an open gives a much flatter picture than counting a click or a login. Track it by dormancy age as well, since contacts inactive for three months usually behave very differently from those inactive for a year.
Watch the cost side with equal attention: complaint rate, hard bounce rate and unsubscribes per thousand sent, each read per message rather than for the sequence as a whole. Then check whether reactivated contacts stay active thirty and sixty days later. A campaign that produces one click and then silence has not recovered anyone; it has only delayed the suppression decision by a month.
Common mistakes
Teams often run the sequence and then leave the silent contacts on the list anyway, which defeats the point. The sequence is a decision procedure: contacts who ignore every message must be moved to a suppression list before the next campaign, or the same dead addresses keep dragging down engagement rates and inbox placement. Write the suppression step into the automation so it does not depend on someone remembering.
The other failure is sending the whole dormant segment at once from your main sending domain. A large batch to addresses that have not engaged in months concentrates bounces and complaints into a single day, which is exactly the pattern filters penalise. Split the segment into small daily batches, verify the addresses first, and start with the most recently active tail rather than the oldest records.
Frequently asked questions
When should I start a re-engagement sequence?
Trigger it after a clear inactivity threshold, such as no opens, clicks, or logins for 30 to 90 days depending on your product. The right window is short enough to catch the contact before they fully forget you but long enough to avoid bothering active users.
What should I do if contacts still do not respond?
Suppress or remove persistently unresponsive contacts to protect your deliverability and keep metrics clean. A non-responder after several attempts is a signal that their address or interest is no longer worth emailing.
How do quiz scores improve re-engagement?
Past quiz results tell you which dormant contacts were genuinely high-fit, so you can give them a stronger, more personal recovery effort. Low-fit contacts get a lighter touch, which saves effort and protects your sender reputation.
When should a contact be considered inactive?
Set the threshold from your own purchase or renewal cycle rather than a standard number. If customers typically buy every two months, sixty days of silence is meaningful; for an annual contract it is not. A practical rule is two to three times your normal buying interval, with a shorter threshold for high-frequency retail and a longer one for considered B2B purchases.
How many emails should a re-engagement sequence contain?
Three or four is the usual ceiling. The first breaks the pattern with a direct question, the second offers a lower frequency or a different topic, and the last states plainly that you will stop sending. Adding more messages rarely lifts recovery and steadily raises complaints, because each additional send lands on an audience that has already declined twice.
Should re-engagement emails include a discount?
Only when the lapse is price-related and you know it. A discount sent to everyone teaches active customers to go quiet before buying and drags margin down across the base. Lead with a question or a change in what you send, and hold an incentive for the final message or for segments whose earlier survey answers pointed at cost as the objection.
What is the difference between re-engagement and a win-back campaign?
Re-engagement targets contacts who are still on your list but have stopped responding, including people who never bought. A win-back targets former customers who actively left or let a subscription lapse, so it addresses a known reason for leaving and usually carries a commercial offer. Re-engagement protects list health; win-back is a revenue recovery play with a different audience.
What should happen to contacts who never respond?
Suppress them rather than delete them. A suppression list stops future sends while keeping the record for compliance and for matching if the person returns through another channel. Deleting the address means a re-import can quietly put them back in the sending pool later. Review the suppressed segment once or twice a year in case a product change makes a single new attempt worthwhile.
Can other channels be used instead of email?
Yes, and they often work better for contacts whose email placement is already damaged. An SMS to an opted-in mobile number, a retargeting audience built from the dormant segment, or a short call to a high-value lapsed account can reach someone your mail no longer reaches. Keep the same suppression rule: if no channel gets a response, stop contacting.
