While we don't test every platform configuration available and we recommend you test thoroughly, we can confirm that Mailchimp for Salesforce supports Person Accounts. We can link our Audience Member records to Contacts, Leads or Person Accounts, as long as there is an Email field on the object.
In the app, you can create new Mailchimp Members or update existing ones with our data wizard. The source can be a report, list view or SOQL query on any object, as long as the source includes an email address.
We also optionally allow you to create or update standard Salesforce objects like Contacts/Person Accounts and Leads from new members.
