I tried to use EXM and upload CSV file which contains first name, last name and Email for two contacts with the same first name and last name but 2 different mails.
Sitecore considers them as they are one contact....is that Sitecore issue?!! and if I want to add configuration to be 2 contacts not one...how can I make that?!!
Copied from OP's comment:
I tried to use EXM with "Regular email campaign" and upload csv file with two contacts with the same first and last name and different emails but after finishing and mapping fields I found that "Contacts expected to be imported is 1"
