A large portion of our contact database does not have email addresses. But they do have either a phone# or postal address. I would like to upload those contacts to my Const Cont account so I can manage my contacts in one area. But I don't want to get charged for additional contacts that I will not be emailing.
I just set up a bunch of "faux", but well-formed, email addresses. And added an optin_status column. Each record in that column is "unsubscribed". Not to my surprise none of the records uploaded. Is there a way to upload additional records to my account that will not count towards my list number and I will not be using for email?
