Re-engagement Campaigns: Win Back Inactive Subscribers

Inactive subscribers hurt your deliverability and cost money. Our re-engagement campaign won back 23% of inactive subscribers.

The Inactive Subscriber Problem

The Cost of Inactivity

Why Subscribers Go Inactive

1. Email fatigue — Too many emails
2. Content mismatch — No longer relevant
3. Inbox clutter — Competing for attention
4. Life changes — Different priorities
5. Better alternatives — Found other sources

The Win-Back Metrics

Re-engagement Best Practices

Do:

• Send to subscribers inactive 60+ days
• Use clear, honest subject lines
• Make unsubscribing easy
• Offer value, not just pleas
• Respect the decision to leave

Don't:

• Send more than 5 emails
• Use guilt or manipulation
• Hide the unsubscribe link
• Re-add unsubscribed users
• Ignore non-responders

The Sunset Policy

A sunset policy automatically removes inactive subscribers:

Our policy:

• No opens in 90 days → Suppressed (not sent to)

Benefits:

• Better deliverability
