Resolve required Mailchimp audience fields
A Mailchimp audience may reject a new contact when a required field has no value. KickoffLabs dashboard’s Mailchimp connection asks for the API key, audience, new-subscriber handling, and whether to send captured custom fields. It does not expose the classic per-field merge mapping screen.
Inspect the selected Mailchimp audience’s field requirements. Keep optional campaign-specific fields optional unless every KickoffLabs signup source supplies them. Submit a synthetic lead with the smallest required form data, then inspect both the KickoffLabs lead and the Mailchimp contact or delivery error. If the field is captured in KickoffLabs but absent downstream, enable Send captured custom fields and retest. Use Connect Mailchimp for the KickoffLabs connection steps.
For destination fields and mapping, follow Mailchimp audience fields overview. Confirm a test contact contains the expected data.
