Maybe adding a “Notifications Settings” button on the UI that directs the user to enter their email address and name (optional).
Could say “notify me when…” My Borrow/Supply ratio reaches ##%, Upcoming protocol changes are scheduled, My COMP rewards reaches ## COMP, News regarding the Compound Protocol, etc.
Should be a way to get the user’s ETH address (if they connected their wallet). Then users are more than just ETH addresses interacting with the protocol because they can be contacted/notified via email.
Maybe even have 5,000 COMP (or anything really) set aside to split evenly between users who link their ETH address and email address.
