If your new contacts are not pushing to MailChimp, you can find out what the most recent error was by navigating to your lead flow or collected forms email sync settings.

  • In your HubSpot account, click the settings icon settings in the main navigation bar.
  • In the left sidebar menu, navigate to Marketing 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 does not 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 to which your collected form or lead flow is connected.
  • Navigate to Settings > List fields and *|MERGE|* tags. Here, you'll see a Put this tag in your content column that will correspond with the error reported in HubSpot.
  • Uncheck the corresponding Required? box so that HubSpot can successfully push to this list.
  • Click Save Changes at the bottom left.
