// migrate to

move to Resend without rebuilding by hand.

mailexodus normalizes your current platform into one portable schema, then checks what Resend can actually import. You get a route report before your agent writes anything.

// try it

bring your data into Resend.

Pick the platform you're leaving and generate a route playbook. The report shows what maps cleanly into Resend's model and what needs review — before you approve writes.

when Resend is the right move.

Resend is a strong fit for teams that want resend teams separating transactional templates and suppressions from lifecycle email operations. The migration risk is rarely the CSV — it is the automation graph: triggers, delays, branches, template references, and consent state. mailexodus puts a portable schema in the middle so those objects are inspected before they become Resend objects.

Automated adapter

Contacts map to subscribers. Segments map to segments. Contact properties map to custom attributes. The contact unsubscribed flag maps to suppression state. Broadcasts map to campaigns. Templates and automations map to content and workflow inventory

Some automation coverage is reconstructed from available metadata Dry-run the report first, then approve writes when the counts and destination gaps look right.

// before you switch

plan the move to Resend.

  1. Authenticate your sending domain in Resend (SPF, DKIM, DMARC) and plan a warmup window — sender reputation is earned here, it does not transfer.
  2. Bring consent and suppression state across first, so unsubscribes and bounces are honored from the first send in Resend.
  3. QA migrated templates and segments inside Resend, and send seed tests before any live campaign.
  4. Keep your current platform active until in-flight automations finish and Resend is warmed and trusted.
// migrate it

start with the route playbook.

The agent prompt returns a route report with source exports, destination imports, skipped objects, and manual-review tasks. When it looks right, wire credentials and approve writes from a controlled machine.
