Techmail updating contacts
I was just wondering if anybody knew what the criteria is for the techmail utility to update contact records?
We have had multiple contact records updated recently by techmail, and i'm having difficulty in determining why this has occurred.
The amendments have been made to the fields First Name and Last Name. I presume this information is being pulled from the email header, but I can't replicate this when I'm trying to test changing the name in the header.
Any input would be appreciated.
