Which email is used when creating new contacts

If you choose to create new contacts or leads in Salesforce from Mailchimp data, the mappings table specifies which email fields should be used. This process involves important considerations:

If a custom email field is selected in Mailchimp for mapping, it's important to note that Salesforce's duplication check is typically only performed on standard email fields. This can lead to the creation of duplicate contacts. We, therefore, advise using the standard Salesforce email field to leverage Salesforce's built-in duplication rules effectively.
