Why are new constituents not being added to our Mailchimp audience despite being added to Altru, and how can this issue be resolved?

If new constituents are not being added to your Mailchimp audience despite being added to Altru, it may be due to incompatible required fields in Mailchimp. Ensure that only email addresses are required for successful list synchronization. If you have additional required fields, such as first and last names, the integration may fail. You can follow the instructions in this support article to correct the issue: “How to Correct the Mailchimp Error About Required Fields in the Data Bridge” If the problem persists, please contact support for further assistance.
