Contacts from non-HubSpot forms or pop-up forms not pushing to Mailchimp

If new contacts from your non-HubSpot forms or pop-up forms are not pushing to Mailchimp after you've connected them, identify the most recent error in your email sync settings.

  • In your HubSpot account, click the settings icon settings in the main navigation bar.
  • In the left sidebar menu, navigate to Integrations > Email service provider.
Here, you'll find the most recent error as reported by Mailchimp, and a button to dismiss the error once it has been resolved. Some common errors include:
  • FNAME must be provided - Please enter a value
  • LNAME must be provided - Please enter a value
  • MMERGE2 must be provided - Please enter a value
  • MMERGE(x) must be provided - Please enter a value

These errors occur because the Mailchimp list has required merge tags for which HubSpot doesn't send a value. HubSpot will always push email addresses to Mailchimp since the email address for a contact is always known. If your forms include a first and last name field, HubSpot should capture this information and send it to Mailchimp as well.

To resolve these errors:

  • Log in to Mailchimp and locate the list your pop-up form or non-HubSpot form is connected to.
  • In the left sidebar menu, navigate to Settings > List fields and *|MERGE|* tags. The value in the Put this tag in your content column will correspond with the error reported in HubSpot.
  • Clear the corresponding Required? checkbox to allow HubSpot to push information to this list.
  • In the bottom left, click Save Changes.
