Updating contacts with upload of spreadsheet

[PaisleyHuntoon]

If I upload a new batch of contacts via spreadsheet and CC finds a similar contact already in my CC database, will it ask if I want to update the current contact or create a duplicate? How "smart" is it? I know some of my contacts have new emails, physical addresses, etc. Will CC recognize this?

If not, how can I solve this issue?

Thanks.

Hello @PaisleyHuntoon ,

Since email addresses are what denote a unique contact, if you upload a list and an email address has new info associated with it (first name, last name, physical address, phone, list membership, etc.), it will update accordingly. If a field is blank or not part of the upload, the existing, respective info for that field will not be updated / erased in the re-upload. A new email address will create a wholly separate, new contact.

Thanks so much. I will give it a try.
