I have been using CC for years now. I've uploaded numerous spreadsheets to get large groups of people uploaded into my contact list numerous times. Just recently I uploaded a list of about 100 but after it uploaded it says the group I created specifically for that list has over 1100 contacts?
I have no clue where the others came from? Is there anyway to know?
I'm using an excel spreadsheet, some contacts that were previously deleted from that spreadsheet were actually STILL uploaded. Not sure why this happened and how to prevent it from doing so?
I'm sorry this happened. It is a strange issue, for sure. Our system just pulls whatever information is listed on the spreadsheet that is being selected. It might be worth taking a look, though. Any chance you could email us at social_support(at)constantcontact(dot)com with your username, the spreadsheet you used, and the list they were added to so we can investigate?
