38% can be re-activated with the right 3-email sequence.
Industry guidance often says you should suppress subscribers after 90 days of inactivity. Our data across 340+ customers tells a different story: with the right re-engagement sequence, 38% of subscribers dormant for up to 18 months can be reactivated.
The winning sequence structure: Email 1 is a simple, low-pressure check-in. No offers, no urgency. A single clear question — 'Do you still want to hear from us?' — with a single CTA. This email typically gets a 28% open rate among dormant subscribers because it feels different from every other email they receive. It's honest.
Email 2 goes out on day 4 if there's been no open. Light social proof of what they've missed, framed entirely around value. Not 'look what you ignored' but 'here's what our engaged subscribers have been using'. Real examples, real outcomes.
Email 3 on day 9 presents a clear, respectful choice: stay in or opt out gracefully. The subject line is simply 'Staying or going?' The body is two sentences and two buttons. This email is counterintuitively your highest performer — when someone who thought they were done sees you giving them a clean exit, many re-engage out of genuine interest rekindled by the respectful framing.
After the three-email sequence, anyone who hasn't engaged should be suppressed — but not deleted. Keep them in a suppressed segment for 90 days in case they contact support or make a purchase, which would trigger re-activation. After 90 days of suppression with no activity, they're done.
