Migrate from Brevo to Mailchimp
Pick a Brevo list and a Mailchimp list. OpenContact reads the contacts from Brevo, keeps a copy, and writes them to Mailchimp. No export file, no upload.
What gets copied
- Subscribed contacts are copied into the Mailchimp list.
- Unsubscribed, bounced, complained or suppressed contacts are not added to the list. They stay excluded.
- Custom fields: Brevo attributes become Mailchimp text, number or date merge fields. Fields that already exist are reused, matched by name, and values are converted to the field type.
- Saved segments are not copied. Rebuild them in Mailchimp from the tags or fields they use.
Check first, then move
- Connect Brevo (API key) and Mailchimp (API key).
- Choose the source list and the destination list.
- Check what will happen. The preview copies nothing. It shows the source count, how many of the first 100 contacts would be copied, excluded or skipped, which custom fields will be created, and how tags arrive.
- Confirm that your Mailchimp plan can take the contacts, then start. Follow fetched, pushed and failed totals as it runs. Pause and resume at any time.
Good to know
Moving to Mailchimp
- Mailchimp limits how many merge fields an audience can have. A field it refuses is left out, and the rest of the migration carries on.
After the move
Sync rules keep Brevo and Mailchimp consistent from now on, and suppression stays honored in both. See suppression sync.
Questions
Will unsubscribed Brevo contacts be re-subscribed in Mailchimp?
No. Unsubscribed, bounced, complained and suppressed contacts are not added to the list. They are excluded at the destination where the tool allows it, and their status is updated in OpenContact. A migration never makes someone mailable who was not mailable before.
What if some contacts fail to copy?
They do not stop the migration. Each failure is kept with its reason. When it finishes you can download the failed contacts as CSV or retry just those contacts, without reading Brevo again.
Can I move more than one list from Brevo?
Yes. Use Move a whole account: each list is matched to a Mailchimp list with the same name, and the lists move one at a time.
Will my automations in Mailchimp fire during the migration?
OpenContact does not run sync rules or verification during a migration. Check your own automations in Mailchimp before you start.
