Emails Using "Send Mail" From Potentials Not Logging

Emails Using "Send Mail" From Potentials Not Logging

Hello, 

We are trying to send emails through the Send Mail link within a potential, and they are not logging/recording under the "Emails" section within that potential. 

It shows up in the mail magnet with return emails, but is not listed at all in the potential or with the lead. 

Help.
