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.
