There can be several reasons why the newsletter form on the page is not submitting and ending up in MailerLite in Webflow. Here are some possible causes and solutions to help you troubleshoot the issue:

  1. Incorrect Form Field Mapping:
  • Check if the form field names in Webflow match the field names in MailerLite.
  • Ensure that the correct form field types are selected for each field in Webflow's form settings.
  1. Missing or Incorrect API Key:
  • Verify that you have entered the correct MailerLite API key in Webflow's form settings.
  • Make sure there are no trailing or leading spaces in the API key.
  1. Form Action URL:
  • Ensure that the form action URL in Webflow is pointing to MailerLite's API endpoint: https://api.mailerlite.com/api/v2/groups/{group_id}/subscribers.
  • Replace {group_id} with the ID of the MailerLite group where you want to store the subscribers.
  1. Verification and Spam Filters:
  • Check your MailerLite account settings to see if you have enabled any verification or spam filters.
  • Disable any filters that might be blocking or marking submissions as spam.
  1. Error Messages and Logs:
  • Enable error logging in MailerLite and Webflow to check if any error messages or warnings are being displayed.
  • Examine the logs to identify any specific issues or error codes that might be causing the problem.
  1. Captcha Integration:
  • If you have integrated any captcha service (e.g., reCAPTCHA) with your form, ensure that it is configured correctly.
  • Make sure you have entered the correct captcha keys and that the captcha service is not causing any conflicts.

If you have tried these troubleshooting steps and the form is still not submitting correctly, it may be helpful to reach out to the Webflow support team or consult with a developer who is familiar with the integration between Webflow and MailerLite.
