Question : How Can I Migrate My Emails to Contacts?

If you’ve been using Mailpro for a while, you may still have some address books in the legacy «email lists» system. The new Contacts system replaces it — with custom fields, tags, segments and a single source of truth across email and SMS. Migration is automatic when you trigger it, takes a few minutes, and is reversible up to 30 days.

What changes after migration

Address books become read-only archives. Each address-book contact becomes a contact in the new system, preserving email, name, opt-in status, subscription date and any custom values. The contact is automatically tagged with the original list name, so you can still target it as a segment.

How to migrate in 3 steps

1. Open Lists → Migration tool. 2. Pick the address books to migrate (we recommend one at a time for traceability). 3. Click Start migration. Mailpro processes 50,000 contacts in 2–5 minutes. You receive an email when it’s done.

What happens to existing campaigns

Already-scheduled campaigns continue to use their assigned address book. Once migration runs, future campaigns target the migrated contact list / segments. There’s no double-send.

Reversibility

For 30 days after migration, you can revert from Lists → Migration history. After 30 days, the original address book is fully archived and can be exported but not used for sending.
