Mailchimp integrates with different form tools to automatically collect and update subscriber data when a form is submitted. These integrations usually work through secure connections such as API keys or authorized access.
Mailchimp integration options include:
- WordPress form plugins: Tools like MetForm, Fluent Forms, and WPForms allow direct integration with Mailchimp, making it easy to sync form submissions with audiences, tags, and custom fields, without third-party automation.
- Google Forms: Google Forms does not connect to Mailchimp natively. Services like Zapier are required to send form responses to Mailchimp automatically.
- Mailchimp native forms: Mailchimp offers its own built-in form builder that generates embeddable HTML forms, suitable for basic signup needs with limited design flexibility.
Important Before You Start #
Before creating or configuring any form, Mailchimp must be connected to your form builder. Without this connection, subscriber data won’t sync, no matter how well the form is designed.
