Mailchain
Mailchain is the communication layer for Web3.

What is Mailchain?
At present, Web3 identities cannot communicate privately. The lack of native communication-infrastructure critically limits usability. Mailchain solves the problem through its open-source communication protocol and unified inbox application. Using Mailchain, anyone can privately email another Web3 identity or blockchain address. It’s as simple as using webmail. Users can manage communications for all their identities, across all protocols in one unified place.
