Re-Engagement Campaign

A re-engagement campaign is a series of emails aimed at reactivating subscribers who have stopped opening or clicking, before they're removed from your list.

Also known as: re-engagement email, reactivation campaign, win-back campaign

Inactive subscribers are a hidden liability: they drag down engagement metrics and deliverability. A re-engagement campaign is your structured attempt to win them back — or cleanly let them go.

How does a re-engagement campaign work?

You identify subscribers who've been inactive for a set period, then send a short series — a reminder of your value, a strong incentive, and a final "do you still want to hear from us?" message.

Why run re-engagement campaigns?

Reactivating an existing subscriber costs less than acquiring a new one. And crucially, those who don't respond can be suppressed, which protects your sender reputation.

Re-engagement best practices

Lead with a compelling reason to return, make the offer strong, keep it short, and set a clear cutoff — remove or sunset those who stay silent.
