Understand the 'Marketing email confirmation status' contact property

The Marketing email confirmation status contact property is a contact property set by HubSpot based on the HubSpot email double opt-in feature. It reflects the status of a contact's eligibility of receiving marketing email.

This contact property keeps track of any contact's interaction with double opt-in email and provides more insight into whether or not your contact has interacted with your double opt-in email. 

The Marketing email confirmation status property has the following values:

• Confirmed: the user's double opt-in status has been confirmed and a follow up email has been sent.*
• Confirmation pending: the user has entered the double opt-in flow has yet to be sent the confirmation email.
• Confirmation email sent: the confirmation email has been sent. HubSpot is waiting for a confirmation via a click. If the double opt-in email bounces, the contact's status will switch back to Confirmation pending.
• User clicked confirmation: the user has clicked on the link in the confirmation email.* 
• HubSpot Rep. marked confirmed: someone at HubSpot has marked the user as confirmed. This is more or less manual via an API call.*
• Customer marked confirmed: a HubSpot user has marked this customer as confirmed during a bulk update.*
• Confirmed from previous behavior: the contact received email prior to double opt-in being enabled.*
• Confirmed due to form: the contact filled out a form on a page where double opt-in is not required.*
