Resubscribe an unsubscribed address
Is there an easy way to resubscribe a contact on their behalf e.g. if the contact rings up and asks to be resubscribed, how can we do this for them without causing hassle for the customer e.g. asking them to find an old email. If they have been unsubscribed in the past, how can we get the Hubspot system to change their status from "unsubscribed from all marketing"?
