What is a Sunset Policy?
A sunset policy is a rules-based process that defines when and how you remove unresponsive contacts from your active email lists. It sets specific criteria, such as "no opens in 90 days" or "no replies after 3 sequences", that trigger automatic suppression of disengaged contacts.
The name comes from the idea of "sunsetting" contacts whose engagement has faded, letting them go gracefully instead of continuing to email them into oblivion.
Why Sunset Policies Matter for Outbound
Continuing to email unresponsive contacts is one of the most common and damaging mistakes in outbound. Every email sent to someone who never opens it signals to mailbox providers that your emails aren't wanted. This drags down your engagement metrics, damages sender reputation, and reduces inbox placement for contacts who might actually respond.
A properly implemented sunset policy protects your deliverability by maintaining a healthy, engaged sending list.
Key Components
- Engagement threshold: Define what counts as "unresponsive" (no opens? no replies? no clicks?)
- Time window: How long before sunsetting (60 days? 90 days? 6 months?)
- Re-engagement step: Run one final re-engagement campaign before sunsetting
- Suppression mechanism: Move contacts to a suppression list, don't delete them entirely
- Regular cadence: Execute sunset reviews monthly or quarterly
Recommended Thresholds
- Cold email: Sunset after 2-3 sequences with zero engagement (typically 60-90 days)
- Warm nurture: Sunset after 6 months of no opens or clicks
- Re-engagement eligible: Contacts silent for 60+ days but under 12 months
Common Mistakes
- No sunset policy at all: The most common mistake, endless emailing of dead contacts
- Sunsetting too aggressively: Some prospects need longer sales cycles
- Deleting instead of suppressing: Keep records for future reference and CRM hygiene
- Not running re-engagement first: Always give contacts one last chance before sunsetting
