Yes and no! Yes, you are rewarded for reading and acting on the messages you receive, but you MUST confirm and verify the email. And that is done with the Proof-Of-Mail system put in place inside of ListNerds. We reward senders, receiver and 'stakers' in ListNerds.
Senders - Rewarded in LISTNERDS token
Receivers - Rewarded in CTP token token
Stakers - Rewarded in both LISTNERDS and CTP tokens
For more detailed explanation of how this all works, make sure you check out our White Paper here
