Amazon SES now supports tenant-level suppression lists

Amazon Web Services has introduced tenant-level suppression lists for Amazon Simple Email Service (SES), addressing a significant limitation in multi-tenant email management. The new feature allows each tenant within a single SES account to maintain isolated suppression lists for bounced and complained-about email addresses, preventing one tenant's email delivery issues from affecting other tenants sharing the same account. Previously, all tenants operated under a shared suppression list, meaning bounce rates or spam complaints generated by one tenant could block email delivery for entirely separate organizations or business units. The capability targets several key use cases including Software-as-a-Service providers managing email campaigns for multiple customers, enterprises separating transactional and marketing communications across different business units, and agencies handling distinct brand communications. Administrators can configure suppression behavior through two primary settings: suppression scope (either tenant-level or account-level) and suppressed reasons (bounces, complaints, or both). AWS automatically populates the appropriate tenant suppression lists based on email delivery feedback, while also providing manual management through API operations including PutSuppressedDestination, GetSuppressedDestination, DeleteSuppressedDestination, and ListSuppressedDestinations with tenant-specific parameters.
