When a person unsubscribes from a Mailchimp email, the Mailchimp membership component within Salesforce will reflect the change once the sync has run (or the refresh icon is clicked).

It is easy to opt a person out of one or more Mailchimp audiences using our member component. Below is a short interactive guide showing the steps.

Our system now supports updating the standard Contact, Lead or Person Account Email Opt Out field, based on the status of related Mailchimp Members. If all related members are marked as ‘Unsubscribed’, the Email Opt Out field will be checked. If any related member is set back to ‘Subscribed’ the field will be unchecked.

Below is an interactive demo on how to enable the option.

Points to note:
The email opt out field in Salesforce is not exclusive to our integration, so it might be updated by users, processes or other apps.

The contact field will be updated when the next primary sync runs.

The contact field sync is one way: Mailchimp Members to the standard email opt out field. If you uncheck the field it will be updated back to checked on the next sync if the person remains unsubscribed in Mailchimp.

Note: The data wizard doesn't check the standard Email Opt Out field before creating new subscribers. Ensure your import source excludes already opted out contacts. However, even if the email is on your source, the wizard won't resubscribe existing members who are already unsubscribed.

To unsubscribe members automatically based on changes to their related contact, please use our Invocable Actions.
