Moving SES from one region to another region

Yes, it is possible to move Amazon Simple Email Service (SES) configurations from one region to another. AWS provides methods to replicate SES email and domain identities across regions.

To accomplish this, you can use AWS SDKs or the AWS CLI to copy your SES configuration, including email and domain identities, from the source region to the destination region. This process typically involves:

1. Retrieving existing identities from the source region
2. Verifying email addresses in the new region
3. Generating DKIM tokens for domains
4. Configuring SNS notifications for identities

If your domains are managed by Amazon Route 53, the process can also include adding or updating Route 53 TXT records for domain verification and DKIM signing in the new region.

It's important to note that when moving SES to a new region, you need to ensure that all components of your email sending configuration (such as domain identities, configuration sets, email templates, and sending limits) are consistent across both the primary and secondary regions. This alignment is crucial to avoid potential issues and ensure proper email delivery and tracking.

AWS has also introduced a feature called Global Endpoints for SES, which allows customers to distribute their SES outbound workloads across two AWS regions automatically. This feature enhances resilience and high availability for email sending operations.

When moving SES to a new region, keep in mind that not all AWS regions may support all SES features. For example, SMTP endpoints might not be available in certain regions. In such cases, you may need to choose a supported region that's geographically close to your target audience or continue using SES in a different region while running other services in your preferred region.

I would recommend looking at this first: Amazon SES now offers Global Endpoints for multi-region sending resilience https://aws.amazon.com/about-aws/whats-new/2024/12/amazon-ses-global-endpoints-multiregion-sending-resilience/

If Global Endpoints does not fit your business needs, you would need to configure email/domain identities for the new region and request for production access for the new region. SES does not have the feature to move verified identity in one region to another.
