MailchimpAdd/Update Subscriber

When you start working with a new customer, the first information you normally grab would be something financial. But wouldn't you want to also add them to your email marketing list? Of course, but that adds a few extra steps in your day, which can be time consuming, as well as difficult to remember in the first place.

Zapier can take care of that for you, all you need to do is worry about nurturing the personal relationship, and let automation handle the rest.

Note: This Zapier integration only creates new MailChimp subscribers from new Wave customers after the Zap has been set up.
