Thanks for posting. If you are adding a file of contacts there isn't a way to merge duplicates. If you are adding one contact at a time you will see a popup to merge duplicates instead of adding the contact a second time. Can you tell me more about which technique you are using to add contacts to the account?
This isn't about when we ADD a file of contacts. This is about contacts already in our in account.
Before the big update, the data was all email address-driven. One email address, one contact.
So now I have existing contacts that I need to merge and I do not want to lose the history of any email address. I.e., one email list import included one email address and a different import used a different email address for that same contact. So it imported the information as a second contact and now there are two contact records in the database for the same contact - one for each email address with its own history. This has happened multiple times in the past since the software was email address driven.
Now I have contacts that need to be merged/combined but I don't want to lose the history for any email address.
