A CF7 Mailchimp integration plugin lets businesses automatically send Contact Form 7 submissions to Mailchimp the moment a visitor fills out a form. Contact Form to Any API connects directly with the Mailchimp API without any Zapier integration, middleware, or custom code.
Best CF7 Mailchimp Integration Plugin for WordPress
Many businesses collect newsletter subscribers and marketing leads through Contact Form 7 on WordPress while managing their email campaigns in Mailchimp. Without an automated workflow, teams often manually export and import subscriber data or rely on third-party automation tools that add extra cost and complexity.
Contact Form to API solves this by sending Contact Form 7 submissions directly to Mailchimp through API requests, allowing subscriber data to sync automatically in real time without leaving WordPress. It’s commonly used for newsletter signup forms, lead generation campaigns, webinar registrations, consultation requests, and marketing automation workflows where every submission needs to be added to a Mailchimp audience instantly.
This setup is widely used for email subscription forms, campaign landing pages, gated content forms, promotional offers, and customer onboarding workflows where Contact Form 7 submissions need to be synced with Mailchimp audiences automatically.

This is where you’ll configure the connection between your contact form and Mailchimp.
Step 3: Create a New Mailchimp Integration
In the integration setup screen:

(Example: Mailchimp Integration) - Enter the Mailchimp API Endpoint URL used to create or update a subscriber in your audience list
This endpoint ensures that form submissions are sent directly to Mailchimp.

In your Mailchimp account:

These headers allow WordPress to authenticate and communicate with Mailchimp properly.
Step 5: Select the Contact Form
Choose the Contact Form 7 you want to connect with Mailchimp. This ensures that only submissions from the selected form are sent to your Mailchimp audience.
Step 6: Map Mailchimp Fields with Form Fields
Now, map your form fields to the corresponding Mailchimp fields.
Common field mappings include:
- Email address
- Name
- Subject
- Message
Accurate field mapping ensures that subscriber data is stored correctly in Mailchimp. Once done, save the integration.
Step 7: Test and Verify the Integration
Submit a test entry using your contact form.
Then:
- Check the API logs inside WordPress
- Confirm that the data has been successfully sent to Mailchimp
- Verify the subscriber appears in your Mailchimp audience list
If everything looks good, your integration is complete.
