This feature is very much needed in the B2B space when smaller company owners use their personal email addresses and their work email addresses interchangeably. We need to be able to send to all designated emails (with multiple primary emails marked) so that they can go into an email workflow and we can monitor activity with a unified contact. Also, it’s not fair to have the client pay for more than one contact record simply because HubSpot is unwilling to address this issue.
