Suppression List
Prevent sends to bounced or complained addresses with Notify’s suppression list.
The suppression list stops you from sending to addresses that previously bounced or complained. Notify checks this list on send so you protect deliverability.
Managing suppressions
Open Suppression List in the dashboard to review and manage suppressed addresses.
How it affects sending
When you call POST /api/public/v1/email/send, Notify checks the recipient against the suppression list. Suppressed recipients are rejected instead of being sent.
Best practices
- Don’t remove suppressions just to force a send — fix the underlying bounce/complaint cause first
- Keep domains verified and authentication (SPF/DKIM/DMARC) healthy
- Monitor logs and webhooks for Bounce and Complaint events
