Implement Tenants in your Amazon SES environment, Part 2: Assessment and planning
AWS SES Tenants Feature Enables Reputation Isolation for Multi-Customer Email Infrastructure Amazon SES introduces tenant-based reputation isolation capabilities that allow organizations to run multiple customers or business units on shared infrastructure while maintaining separate email reputations. Part 2 of this series focuses on assessment and planning for implementing or migrating to tenant-based architecture. The feature enables ISVs, enterprises, and SaaS platforms to assign dedicated configuration sets, sending identities, and templates to each tenant, ensuring deliverability issues with one tenant don't affect others. The article provides guidance on pre-migration assessment, recommended tenant structures (1:1 mapping between tenants and customers), and resource sharing strategies to minimize disruption during implementation.
