There could be several reasons why the new email collection form in the hero header of the Webflow home page is not working with Mailchimp integration. Here are a few possible explanations:
1. Integration Setup: Make sure you have properly set up the integration between Webflow and Mailchimp. Double-check if you have entered the correct API key and have connected the appropriate Mailchimp list to the form. In Mailchimp, verify if the required fields (such as email address) are correctly mapped with the form fields.
2. Form Properties: Check the properties of the email collection form in Webflow. Ensure that the form submission method is set to "POST" and that the form is set to submit to the correct Mailchimp endpoint. You can find the Mailchimp endpoint in the Mailchimp API documentation.
3. Field Names: Verify if the field names in the Webflow form match the field names in your Mailchimp list. If there is a mismatch in field names, the data may not be properly transferred from Webflow to Mailchimp.
4. Validation Errors: Look for any validation errors that may be preventing the form from being submitted. Check if there are any required fields that are not properly filled out or if there are any input patterns that need to be matched, such as a valid email format.
5. Compatibility Issues: Ensure that the version of the Mailchimp integration you are using is compatible with Webflow. Sometimes, certain versions of integration plugins may not work as expected due to updates or changes in either Webflow or Mailchimp.
6. Testing and Troubleshooting: To identify the issue, try submitting the form and monitor the browser console for any error messages. This can provide insights into the specific problem. Additionally, test the form submission directly on the Mailchimp side to see if the issue lies within Webflow or Mailchimp.
If you have checked all these aspects and the integration is still not functioning properly, it might be helpful to reach out to the Webflow support team for further assistance. They have the necessary expertise to investigate the issue more thoroughly and provide a tailored solution.
