Migrate from Kit to Mailjet
Pick a Kit list and a Mailjet list. OpenContact reads the contacts from Kit, keeps a copy, and writes them to Mailjet. No export file, no upload.
What gets copied
- Subscribed contacts are copied into the Mailjet list.
- Unsubscribed, bounced, complained or suppressed contacts are not added to the list. They stay excluded.
- Custom fields: Kit custom fields become Mailjet contact properties. 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 Mailjet from the tags or fields they use.
Check first, then move
- Connect Kit (API v4 key) and Mailjet (API key + secret).
- 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 Mailjet 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 Mailjet
- Unsubscribed, bounced and complained contacts are excluded from campaigns in Mailjet instead of added, so a later import cannot bring them back by mistake.
- Mailjet keeps one contact per person. Someone in several lists is one contact there, added to each list.
After the move
Sync rules keep Kit and Mailjet consistent from now on, and suppression stays honored in both. See suppression sync.
Questions
Will unsubscribed Kit contacts be re-subscribed in Mailjet?
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 Kit again.
Can I move more than one list from Kit?
Yes. Use Move a whole account: each list is matched to a Mailjet list with the same name, and the lists move one at a time.
Will my automations in Mailjet fire during the migration?
OpenContact does not run sync rules or verification during a migration. Check your own automations in Mailjet before you start.
