Bounced email

Bounced email

I have a problem with the bounced emails. Some contacts for some reason are show like bounced, but in fact the already exist and I need them in zoho campaigns, because they are really important for the campaign that i want to sent.
There is any chance that i can add it to the contact list? Like accepting the fact that maybe noone will receive the e-mail, but at least that the e-mail will be there.
Please and thank you:)
