update contact list

[NewRochelleSchools]

I need to delete old lists and add new. When I add the list of 3019 contacts, only 342 uploaded. What went wrong?

Hello @NewRochelleSchools ,

You can view your import/export activity via the Contacts page. Based on what's showing, it looks like you're uploading a lot of contacts that have already been uploaded, so it's just updating the data for those accordingly, rather than uploading them as wholly new.
