Re-engagement Email Subject Lines
Re-engagement emails go to people who have stopped opening, so the subject line has to break the pattern. Honest, personal lines and a clear choice (stay or go) usually work better than another promotion.

Why these work
Be direct about the gap
“Still want to hear from us?” acknowledges the silence and asks for a decision.
Offer a choice
Fewer emails or a topic preference keeps people who would otherwise unsubscribe.
Let go gracefully
Removing people who never respond protects your sender reputation for everyone else.
Write your own re-engagement lines
Describe your email and the AI generator writes 12 options in this style, each scored.

Frequently asked questions
What should a re-engagement email subject line say?
Acknowledge the absence and ask a simple question: “Still want to hear from us?”, “Should we keep in touch?”. For lapsed customers, a concrete reason to return can work too.
When should I send a re-engagement campaign?
Commonly after 90–180 days without opens or clicks, depending on how often you email. Because of Apple Mail Privacy Protection, clicks are a more reliable activity signal than opens.
What do I do with people who don't respond?
Suppress or remove them after the sequence. Mailing unengaged addresses for months can hurt inbox placement for your whole list.
