Amazon SES scores higher on Price / Value — 98/100 versus 75/100 for Mailgun. If price / value is your primary decision criterion, Amazon SES is the stronger choice in this head-to-head.
Switching between transactional email tools is generally possible but involves migration effort: exporting your data or configuration from Amazon SES, re-importing or reconfiguring in Mailgun, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Mailgun on a non-production project first before migrating.
Amazon SES (74/100) is the better fit for teams who prioritise price / value — its strongest dimension — and who want a free entry point.
