leave Mailgun. keep the work.

// the playbook

how an agent migrates Mailgun → Sequenzy.

This is exactly what mailexodus hands your agent: authenticate, then for each object type — read it from Mailgun, map it to the portable schema, write it to the destination. mailexodus never writes; your agent does, with this report in hand.

01 · authenticate

Create a Mailgun private API key with read access to mailing lists, suppressions, and templates. Paste BASE_URL|DOMAIN|API_KEY, for example https://api.mailgun.net|mg.example.com|key, or JSON with baseUrl, domain, and apiKey

guardrails
  • Sender reputation is earned at the destination — set up SPF/DKIM/DMARC and a warmup ramp; it does not transfer.
  • Keep the source platform active until authentication, warmup, and in-flight automations have finished.
  • Honor suppressions before the first send.
  • After writing, verify counts per object type against the source before switching live sends.
