I wonder if someone can help me with building this zap.
Some of my subscribers want to change their e-mail addresses, and we have a specific department handling all the calls for these. Instead of manually updating the users, I want to create a Zap that finds the original e-mail address listed in Mailchimp, and update it with the new e-mail address.
However, it seems difficult to do this as the platform assumes everyone updates their e-mail addresses themselves (I can only dream!)
