MailingCore vs Resend
Resend's DX is excellent. MailingCore plays the same developer-first league with three cards of its own: a European company with EU data, newsletter and sequences included, and direct frontend sending.

Choose MailingCore if…
- Your priority is GDPR and EU data residency without intermediary clauses.
- You want transactional AND newsletter/sequences in the same tool.
- You need to send from the frontend (forms, no-code) as well as from the server.
- You want non-technical people editing templates in a panel, not in React code.
Resend may fit you better if…
- Your team lives in the React Email ecosystem and wants templates as components.
- You need the scale and maturity of battle-tested infrastructure.
- Its brand and community are already part of your reference stack.
FAQ
Can I migrate my templates from Resend?
If you use React Email, render your templates to HTML and paste them into MailingCore's editor (code mode, Monaco) with {{mustache}} variables. Suppressions and contacts import via API.
What about deliverability?
You verify your domain with SPF, DKIM and DMARC from the wizard (real verification, not cosmetic), and bounce/complaint suppressions apply automatically before every send.
Are you as big as Resend?
No, and we don't pretend to be: MailingCore is a young European product that's transparent about its status. If you want proximity, EU data and a platform that also does newsletters, that's our offer.
