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.
