**Your software**  
My Mautic version is: 4.4.3  
My PHP version is: 7.4.29  
My Database type and version is: 10.2.44-MariaDB

**Your problem**  
My problem is:

Is there a way to find out who the merged contacts are when importing?

It will merge based on the unique identifier which is likely to be an email address.

A simple way would be to do an export of your contacts before the import and then compare that to the import csv and look for duplicate email addresses.

I am not sure it can be done inside of the Mautic UI.

Thanks. I guess that is what needs to happen before importing.

I’ve got easier solution. When you do import add some tag, as “import20221013”. After import type in contact search window: “tag:import20221013”, and order contact by ID. The oldest were merged.

It makes sense. Will give it a shot.

I stumbled across the solution tonight in Mautic. When you do an import, Mautic will indicate which contacts were inserted and which contacts were updated (merged).
