Manage suppressions, bounces, spam, and blacklist data
Keep addresses and domains that should not receive mail out of production sends.
In the app→Suppress & Blacklist
Protection layers
- Suppression
- Exact email or domain-level exclusions, entered manually or imported, optionally scoped to a list.
- Global Bounce
- Addresses recorded as bounced across the tenant, with import and export support.
- Global Spam
- Addresses associated with complaint events.
- Blacklisted IPs and domains
- Monitoring views for affected infrastructure and detailed records.
Account-level recipient handling
General settings can leave bounced, spam, or suppressed recipients unchanged, mark them unsubscribed, or mark them inactive. The selected behavior applies to current and future matching recipients.
Do not casually re-enable suppressed recipients
A suppression may represent a legal preference, complaint, or repeated delivery failure.
