Your crypto is your unique ID. We provide a free email for it. DAOs can use it to inform token holders about new proposals and/or discussions, and current voting status. This gives Web3 developers a way to reach to their users, from either Web2 backend/indexer, or from within smart contracts. Users need to know when their orders are executed, or when their account is at risk. Email is a proven user engagement method. Web3 projects can finally catch up.
