There could be several reasons why your Mailchimp integration is not working even though the sign-up process appears to be successful. Here are some possible causes and troubleshooting steps to consider:

API Key: Make sure you have entered the correct API key in your Webflow project settings. An incorrect or expired API key can prevent proper communication between Webflow and Mailchimp.
Form Settings: Ensure that your form in Webflow is properly set up to integrate with Mailchimp. Double-check that the form is connected to the correct Mailchimp list and that the required fields are mapped correctly.
Double Opt-in: If you have enabled double opt-in in your Mailchimp account, check your subscriber list to see if the submissions from Webflow are being placed in the "Pending" or "Unsubscribed" status. Subscribers in these statuses may need to confirm their subscription before being added to your list.
User Notifications: Review the email notifications that are set up in your Mailchimp account. It's possible that these notifications are not being triggered or are being filtered out as spam. Check your junk/spam folders to confirm if the notifications are being delivered.
Spam Filters: Mailchimp's automation emails (such as confirmation emails) can sometimes trigger spam filters. Make sure to check your spam folders and adjust your spam filter settings if necessary.
Custom Code: If you have custom code running on your Webflow site, double-check if it is interfering with the Mailchimp integration. This could be JavaScript conflicts or code that modifies form submission behavior.
Mailchimp Service Issues: Occasionally, Mailchimp may experience temporary service issues that affect integrations. Check the Mailchimp status page or their support documentation for any reported issues.
