Create A Segment Based On The Email Client Used By Contacts

About this task

The Primary Email Client criterion allows you to create segments based on the email client used by contacts to open emails you send them.

The primary email client stored for a contact is a reflection of the email client they use most (mode) to open emails you have sent them. This could be a mobile, web, or desktop email client.

Tip: Go to Contacts > Search, search for your contacts, then view the Primary Email Client column to find out the email client a contact uses when opening emails you have sent them.
