Using clean install of Mautic 2.10 (new database, key correctly placed on email field by Mautic and custom fields were not edited), I’ve imported a large database of about 250.000 unique email addresses via cron job (no errors). Contact count and report of import shows that Mautic inserted about 140.000 contacts and updated about 110.000. I suspect, that Mautic merges contacts with the same string before @.  
  
  
  
Example of a problem:  
  
[somename@gmail.com](mailto:somename@gmail.com) would be inserted normally on an empty contact list, but subsequent import of [somename@yahoo.com](mailto:somename@yahoo.com) would update [somename@gmail.com](mailto:somename@gmail.com) instead of inserting it.  
  
  
  
Any ideas how to get Mautic to insert all of the unique contacts and not merging them?
