THE ISSUE

You received a message saying that:

The syncing between CCB and Mailchimp has been interrupted/skipped for sync pair <CCB Group / Saved Search> and <Mailchimp Audience/group>.

Main Issue (Highly Probable)

The issue is likely with the current merge fields on your Mailchimp (MC) account.

POSSIBILITY 1

You may be using a MC form connected to your group/audience with fields you marked as REQUIRED. E.g., food allergy. When CCBChimp syncs, MC rejects the entire sync of that profile if the required field is blank.

Suggestion: Marking those fields as not required might fix the issue. If you need to require specific merge fields, link the form to a different group that isn’t syncd through CCBchimp.

POSSIBILITY 2

Another possible issue is that the contacts have invalid merge field values set, but the error is only triggered WHEN we try to sync. So it works fine for you if you use MC only, but MC suddenly rejects that record as it sees an error in the value of the merge field.

Say you created a merge field for MOMS with options like YES or NO but you added (YES)—including parentheses—or something like that. Then that would cause an error.

Suggestion: Fixing those merge fields with the potential bad values should help.

At the moment, this is our best guidance.

To now, we have seen that the issues are on the Mailchimp side. So, we recommend looking at the records which are failing and checking out the values in the merge fields.
