AWS SES Tenants Feature Part 3: Step-by-step implementation guide for reputation isolation This guide provides a comprehensive implementation roadmap for Amazon SES's new tenants feature, enabling users to isolate sender reputation across multiple customers or business units within a single SES account. The article covers a four-step migration process: preparation (verifying SES V2 API usage and SDK versions), creating tenants, associating resources (domains, configuration sets, IP pools), and updating sending code. It includes practical Python code examples using Boto3 for programmatic tenant provisioning and details the seven essential SES V2 API operations required for tenant lifecycle management. The tenants feature allows automated reputation policies, deliverability issue isolation, and automatic pause mechanisms to limit damage from problematic senders while preserving overall sender reputation.
