Mike_Eastwood, thank you for your answer. Is it possible to find documentation or help about Hubspot-Mailchimp integration in Starter subscription? At the moment I’ve only found Hubspot Help with information that Hubspot will “push” the data about the contacts who filled in the forms. And nothing else. Especially no information whether I can see in Hubspot which email campaigns were sent via Mailchimp to the contact and whether he opened any of them.
