My emails reach a contact every time who is not part of that particular list.

How can  I  be sure that my emails reached to the desired inboxes only

Hi @WorkSocialAHC. Since we do not know which contact should not be receiving your emails, it's hard to determine what our next steps should be. It's possible that if they are a recipient of a role address (such as info@ or admin@), they would be receiving an email they did not opt in to. Could you please email us at communitysupport(at)constantcontact(dot)com with the contact's email address and what list they are not on?
