Someone fills in a form you built with Gravity Forms, and a new subscriber appears in your Mailchimp audience. Every field maps straight across the instant the form is submitted — a direct, real-time connection that runs entirely on your own WordPress site.

Everything you need to know about the Gravity Forms & Mailchimp integration
No. Install Integrazo Automator, authorise Mailchimp once, pick the form as your trigger, map the entry fields to Mailchimp merge fields and switch the connection on. There is no webhook URL to paste and no JSON to write.
The one you pick when you build the connection. Every subscriber it adds goes to that audience, with the merge fields and tags you set.
Yes. Every one of your entry fields is offered against every merge field on your Mailchimp audience — pick the ones you want mapped.
Not with Add Subscriber — Mailchimp itself rejects a repeat email rather than updating it. Use Add or Update Subscriber instead, and a matching email is updated rather than rejected.
Yes. Add a filter condition on any mapped field — contains, equals, starts with, is empty and the rest, combined with AND/OR — and only entries matching it are sent to Mailchimp. Everything else is skipped and still shows up in your Logs.
The run is logged as failed with the error Mailchimp returned, and the submission is still saved in WordPress — nothing is lost. Once the problem is fixed, the next matching submission goes through as normal.
No. The connection runs on your own WordPress site and talks to Mailchimp directly. The OAuth token is encrypted in your database, and there is no middleman service holding a copy of your data.
The core plugin is free on WordPress.org and covers a single connection. Pro adds unlimited connections, multiple audiences per connection, and tag automation, and priority support.
