// migrate to

move to MailerSend without rebuilding by hand.

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

// try it

bring your data into MailerSend.

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

when MailerSend is the right move.

MailerSend is a strong fit for teams that want mailersend 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 MailerSend objects.

Partial automated adapter

Recipients map to subscribers when email identity and consent state are sufficient. Suppressions map to suppression records. Templates map to transactional templates

Campaign, segment, list, and automation export were not verified Dry-run the report first, then approve writes when the counts and destination gaps look right.

// before you switch

plan the move to MailerSend.

  1. Authenticate your sending domain in MailerSend (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 MailerSend.
  3. QA migrated templates and segments inside MailerSend, and send seed tests before any live campaign.
  4. Keep your current platform active until in-flight automations finish and MailerSend 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.
