Why are Contacts added via the HubSpot CRM not eligible for marketing emails?

Contacts who are added via the HubSpot CRM are not elligible for marketing emails sent from the HubSpot Marketing platform. You may notice their 'Email Confirmation Status' property is automatically set to 'Awaiting Double Opt In' upon creation.

In order for a contact who was added via the HubSpot CRM to become eligible to receive marketing emails, they must either:

• Fill out a HubSpot form
• Or, be imported via the HubSpot Marketing platform with the import type set to import Contacts (as opposed to importing an opt out list). Importing the list will change the 'Email Confirmation Status' to 'Customer marked confirmed', which means they are eligible for marketing emails.
