Migration guides for moving transactional email from Mailgun, SendGrid, Brevo, Postmark and Mailjet to wemail: what the shim translates, which templates and suppression lists import automatically, how the weighted DNS cutover works, and how to roll back. Each guide is the same four steps with the details of your current provider filled in.
01
Paste your API key
Templates and suppressions auto-import. Verify your domain.
02
Change one line
Point your client's host at api.wemail.io/bridge/<provider>. Everything else stays.
03
Cut over gradually
