Implement Tenants in your Amazon SES environment, Part 3: Implementation guide

This article provides a comprehensive implementation guide for Amazon SES Tenants, enabling isolated email reputation management across multiple customers or business units within a single AWS account.

• Create tenants programmatically during customer onboarding using CreateTenant API
• Associate resources (domains, configuration sets, IP pools) to tenants for isolation
• Add TenantName parameter to SES V2 API calls or X-SES-TENANT header for SMTP
• Configure granular IAM policies restricting tenant access by role and tenant name
• Monitor tenant status changes and reputation findings via EventBridge to CloudWatch
• Set reputation policies (Standard/Strict/None) to auto-pause problematic tenants
• Manage tenant lifecycle: create, associate resources, update status, delete cleanly
• Resources can be shared across multiple tenants while maintaining separate reputation tracking

The guide demonstrates how SES Tenants provide reputation isolation, automated protection against deliverability issues, and scalable multi-tenant email infrastructure with minimal application code changes.
