Amazon Simple Email Service Expands to Three New AWS Regions, Enhancing Global Reach and Reliability
Seattle, WA – June 30, 2025 – Amazon Web Services (AWS) is pleased to announce a significant expansion of Amazon Simple Email Service (SES) availability, with the service now officially launched in three new AWS Regions. This strategic rollout further strengthens AWS’s commitment to providing customers with highly available, scalable, and performant email sending and receiving capabilities across the globe.
The newly supported AWS Regions are:
- AWS Region: Asia Pacific (Hong Kong)
- AWS Region: Europe (Milan)
- AWS Region: South America (Mexico City)
This expansion is a direct response to growing customer demand for localized email infrastructure, enabling businesses to send and receive emails closer to their end-users. By leveraging SES in these new regions, customers can benefit from reduced latency, improved delivery rates, and enhanced data residency options, which are crucial for meeting regulatory compliance and providing a superior customer experience.
Key Benefits of SES Availability in New Regions:
- Reduced Latency: For businesses operating in or serving audiences within the Asia Pacific (Hong Kong), Europe (Milan), and South America (Mexico City) regions, deploying SES in these local AWS Regions will significantly decrease the time it takes for emails to be sent and received. This improved performance is vital for time-sensitive communications, marketing campaigns, and transactional emails.
- Enhanced Reliability and Availability: Distributing email workloads across multiple AWS Regions provides greater resilience. If an issue were to affect one region, customers can continue to send and receive emails from other available regions, ensuring business continuity.
- Improved Deliverability: Sending emails from a region geographically closer to the recipient’s mail servers can positively impact deliverability rates by reducing network hops and potential points of failure. This means emails are more likely to reach the intended inboxes.
- Data Residency and Compliance: For organizations with specific data residency requirements, having SES available in these new regions offers greater flexibility in storing and processing email-related data within designated geographical boundaries, aiding in compliance with various data protection regulations.
- Cost Optimization: While not explicitly stated, proximity of services can sometimes lead to more predictable and potentially optimized network costs for data transfer.
Amazon SES is a highly scalable, cost-effective, and flexible outbound and inbound email-sending service that developers can use to send marketing, notification, and transactional emails from applications. With this latest expansion, AWS continues to invest in making its services accessible and performant for a diverse global customer base.
Customers can now begin utilizing Amazon SES in the Asia Pacific (Hong Kong), Europe (Milan), and South America (Mexico City) Regions by simply selecting the desired region when configuring their SES resources. AWS encourages customers to review the AWS documentation for detailed guidance on migrating or setting up new email workloads in these newly available regions.
This expansion underscores AWS’s ongoing commitment to empowering businesses with the tools they need to communicate effectively and reliably with their customers worldwide.
