Someone in my firm is trying to add me as user to Campaigns, but I already created my Campaigns account with my email roman@modelcapitalmgmt.com. So when he tries to add me as user, he's getting a message: 

This email address has been already used in some other organization. So you cannot add/invite this user.

Can you please delete my Campaigns account for roman@modelcapitalmgmt.com, so he can add me?

Thank you,

Roman Chuyan
