It looks like the "EmailEvents" table contains the Email address of the user (although I am not sure if you can use that to get a user's information or not). You can do a join on the "NetworkMessageId" column

Actually, breaking the problem would help here Have a look at the logic app run history and look at the output parameters for Entities - Get Accounts steps and that should give you the dynamic field for email.
