Complete Suppression Management
Add, remove, check, audit, and cross-reference suppressions. Integrated with bulk validation and the sending API.
Bulk Add and Remove
Import and manage thousands of suppressed addresses at once via API or dashboard upload. POST arrays of addresses with reason codes in a single request.
Email and Domain Types
Suppress individual addresses or entire domains. Block all mail to a company with one entry. Both types are checked during validation and sending.
Auto-Suppression
Hard bounces and spam complaints are automatically added to your suppression list in real time. No manual intervention required to protect your sender reputation.
Audit Trail
Every suppression change is logged with timestamp, source (manual, auto-bounce, complaint), and reason. Full compliance trail for GDPR and CAN-SPAM audits.
Suppression Stats
Dashboard showing total suppressions, breakdown by type (bounce, complaint, manual), and growth trends over time. Spot list hygiene issues before they escalate.
Cross-Reference
Match your sending list against your suppression list to catch addresses that should not receive mail. Prevent accidental sends to previously bounced or complained recipients.
Add Suppressions in One Request
POST an array of addresses with reason codes. The API handles deduplication and audit logging automatically.
curl -X POST https://api.mailodds.com/v1/suppression \ -H "X-Api-Key: mo_live_..." \ -H "Content-Type: application/json" \ -d '{ "suppressions": [ { "email": "bounced@example.com", "reason": "hard_bounce", "source": "manual" }, { "domain": "defunct-company.com", "reason": "domain_block", "source": "manual" } ] }'
{ "added": 2, "duplicates": 0, "errors": 0 }Bounces and Complaints Are Suppressed Instantly
