 * Hello, I am having some issues with info being mapped to the wrong contact about
   50% of the time. I have the Primary Key set to ‘First Name & Last Name & Email,’
   but the feed seems to only be matching the First Name.
 * Am I correct in that this should be looking for contacts where the First Name
   AND Last Name AND email all match the entry, or is my understanding of Primary
   Key wrong? Any suggestions on how to cut down on the incorrect mapping? Thanks!

 * Hey [@mandie1313](https://wordpress.org/support/users/mandie1313/),
 * Thank You for the question,
 * You should only put 1 primary key and not multiple, we recommend you add th email
   as the primary key because it is what is most unique.
 * Thank You – Sam
