// migrate from

leave Mailjet. keep the work.

mailexodus reads Mailjet over its API and normalizes subscribers, lists, custom fields, suppressions into one portable schema — so you move with a report, not a 40-item checklist.

// why teams leave

why teams leave Mailjet.

  • →
    Mailjet migrations need an explicit boundary around what the API exposes.
  • →
    Teams want a dry-run report before rebuilding subscribers, lists, custom fields, suppressions.

    Automation import is not part of current native coverage

// the playbook

how an agent migrates Mailjet → Sequenzy.

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

01 · authenticate

In Mailjet, open Account Settings, REST API, then paste credentials in API_KEY:API_SECRET format

  • tags
  • segments
  • automations
  • sender reputation and domain warmup
  • historical analytics, revenue attribution, and aggregate reporting
  • contacts already mid-flight inside active automations
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.
