The Unsubscribe link in emails are connected to a constituent account. If that recipient forwards the email to someone and they click 'unsubscribe' it unsubscribes the original recipient, your constituent. Mailchimp has a "Forward to a Friend" button you can use that allows forwarding and will not unsubscribe the original receipient. Please add this function. We have had constituents inadvertently unsubscribed because of this. Thank you.
