Re-Engagement Email Campaign Decision Guide
Choose eligible inactive contacts, set a lower send cadence, evaluate re-engagement signals, and suppress people who no longer respond.
A re-engagement email campaign should not be a last-minute blast to every quiet subscriber. It should be a controlled decision process: identify people who may still expect your email, reduce unnecessary sending, measure meaningful responses, and suppress contacts when continued outreach is no longer justified.
Define inactivity for your sending pattern
Inactivity should reflect your normal email cadence and customer lifecycle. A weekly newsletter might review contacts after several months without a meaningful action, while a seasonal business may need a longer window. Avoid copying a universal 30-, 60-, or 90-day rule without considering how often subscribers normally hear from you.
Use reliable engagement evidence. Clicks, replies, purchases, account activity, preference updates, and consented website activity can all help. Opens alone are weak evidence because privacy features and image blocking can make them inaccurate. A delivered message is not proof of attention.
Separate contacts into at least three groups:
- Never engaged: Subscribed or imported but have shown no meaningful activity.
- Previously engaged: Clicked, purchased, replied, or otherwise participated before becoming inactive.
- Active outside email: Ignore email but still use an account, attend events, or buy through another channel.
These groups should not receive identical treatment. Someone active elsewhere may need a preference prompt, while a contact who never engaged may warrant faster suppression.
Decide who is eligible to receive a message
Start with permission and reasonable expectations, not campaign size. Confirm that each recipient has valid consent or another documented lawful basis, such as legitimate interest where applicable. Legitimate interest requires an actual assessment of necessity, expectations, and potential impact; it is not a substitute for missing records or expired permission.
Use this decision sequence:
- Check consent and source. Know when, where, and how the address was collected.
- Check exclusions. Remove opt-outs, complaints, hard bounces, blocked addresses, and contacts covered by internal do-not-contact rules.
