Alternatives to the email APIs teams already know
If you want an alternative to Resend, EmailJS or Amazon SES with real EU data residency — not just a sending region — these pages say when to switch and when to stay.
What counts as a serious email API alternative?
An alternative to Resend, EmailJS or Amazon SES is not merely “another API that sends mail”. For a European team, the legal risk sits where logs, templates and addresses are stored — not which region the SMTP packet leaves. MailingCore is a developer email platform with EU servers, native GDPR, a JS SDK, versioned templates, newsletter tooling and an MCP server for AI agents. The Free plan includes 100 emails per month and 5 templates, no credit card. It does not replace SendGrid at planetary scale or Amazon SES as raw AWS transport; it does replace stacking a US transactional API plus a separate campaign tool when you want one API and data in Europe.
Resend
Excellent DX; account data stays in the US even if you send from Ireland.
