Migration guide

How to migrate from Resend to Mailgun

Whether you’re switching from Resend to Mailgun or the reverse, Mailgun offers step-by-step support and documentation to make the transition smooth.

Mailgun’s support and deliverability team can guide you through each step – especially if you’re moving from a simpler provider like Resend to a more robust platform. 

Migration checklist:

  • Export templates and variables — Download your HTML, MJML, or React templates and make sure template variables and API fields are mapped correctly between providers.

  • Map events and webhooks — Review delivery, open, bounce, and failure events, then update any webhook consumers or analytics pipelines that rely on them.

  • Verify your sending domains with the new provider and monitor DMARC alignment throughout the transition.

  • Warm up new IPs and domains — Increase sending volume gradually (for example, 1k/day to 10k/day and beyond) while monitoring blocklists and inbox placement.

  • Validate deliverability before full cutover — Compare inbox placement between providers and keep your previous provider active until you’re confident in performance.
