Re-Engagement Campaign Template
Reactivating Inactive Subscribers Without Hurting Deliverability
Version 2026-04 · Cloud Server for Email
When to Run Re-Engagement
| Trigger | Segment | Goal |
|---|---|---|
| Subscriber inactive 90–180 days | Cooling tier | Confirm continued interest before suppressing |
| Before major campaign to full list | All 90-day+ inactives | Clean list before large volume send |
| Before IP warming or migration | All inactives | Ensure warming uses only engaged subscribers |
| Declining open rate trend (3+ months) | Bottom 30% by engagement | Identify subscribers to suppress before rate falls further |
Re-Engagement Email Structure
Subject line options:
- "Still interested in [topic]?"
- "We miss you, [First Name] — still want updates?"
- "Quick question before we stop emailing you"
- "Are these emails still useful to you?"
Body content: Keep short (under 150 words). Remind them of the value they signed up for. Give them a clear YES choice (click button = stay subscribed) and make it easy to unsubscribe. Do NOT send a promotional campaign as your re-engagement email — it will get more spam complaints.
Example re-engagement email body:
Hi [First Name],
We noticed you haven't opened our emails in a while, so we wanted to check in.
If you still want to receive [content type] from us, click the button below — and we'll keep sending.
If not, no worries — click unsubscribe and we'll stop.
[KEEP ME SUBSCRIBED] [Unsubscribe]
Send Strategy
- Send re-engagement from a SEPARATE IP than your main marketing pool
- Start with 91–120 day inactives; don't send to 180+ day inactives in the same batch
- Send on a weekday (Tuesday–Thursday) during business hours for your recipient's timezone
- Do NOT send more than one re-engagement email per subscriber per campaign sequence
- Wait 7–14 days before suppressing non-responders
Post Re-Engagement Actions
| Response | Action |
|---|---|
| Clicked "Keep Me Subscribed" | Reset engagement date; return to active segment; send normal campaigns |
| Opened but didn't click | Count as mild re-engagement; keep for 30 more days; suppress if no further engagement |
| Unsubscribed | Add to suppression; remove from all lists |
| No response after 14 days | Suppress from all future campaigns |
| Marked as spam | Suppress immediately; investigate if complaint rate spikes |
Suppressing inactive subscribers before your next major campaign is the highest-ROI deliverability action available. It reduces complaint rates, improves open rates (denominator shrinks), and signals engagement to ISPs — all of which improve inbox placement for your engaged subscribers.
