This article provides a comprehensive guide for migrating to Amazon SES, covering migration scenarios, step-by-step implementation, and best practices for email deliverability.

• Three migration scenarios: on-premises to SES, cloud provider to SES, hybrid solutions
• Identify email use cases: marketing, transactional, business communications, inbox, OTP
• Separate marketing and transactional traffic using subdomains for better management
• Verify domain ownership to enable DKIM, SPF, DMARC, and BIMI authentication
• Test in sandbox environment before requesting production access
• Choose IP management strategy: shared, dedicated, managed dedicated, or BYOIP
• Warm up new IPs gradually, starting small and doubling volume every other day
• Generate SMTP credentials and configure SMTP endpoint for applications
• Monitor bounces, complaints, and deliverability using reputation metrics and VDM
• Implement ramp-up/ramp-down strategy targeting engaged recipients first

Following this systematic migration approach ensures smooth transition to Amazon SES with maintained deliverability and domain reputation.
