Help needed: Project involving Cardano smart contracts to send messages

Hey Cardano Developers, I am trying to find a developer who is interested in using Cardano’s smart contract protocol to send and verify messages through email. I am looking to provide an extra layer of security on app I’ve already created. I’m not sure of the best way to integrate this technology. Anyone have experience with a similar idea? Any ideas on the best way to integrate Cardano to a communication app?

Likewise I am interested in exploring the replacement of the email addresses as the nodes of communication, I would want it to be nodes through Cardano blockchain, or smart contracts protocol for each message. Not sure if this is possible, but I wanted to find out. Any Cardano Developers interested in discussing further?
