Your wallet is
the whole address book.
ETHMail turns an Ethereum account into a mailbox. Write to any 0x address for free, or spend gas to push a message out to an ordinary inbox — priced by the byte, settled onchain.
One signature. No password, no confirmation email, no account to create.
Settle in the coin you hold
The fee is quoted in USD and converted at the spot rate when you send. Every rail is verified by reading its own chain before your mail leaves the building.
How a message gets out
Everything inside the network is free. Leaving it costs gas, and that gas is a real transfer your wallet signs.
Sign in
A server-issued nonce, signed by your wallet and verified against your address. Nothing else is stored about you.
Address it
A 0x address, an ENS name, or an ordinary email address. ETHMail works out which side of the bridge it belongs on.
Pay the gas
Only for outbound mail. Metered per byte, quoted in USD, settled in SHCX, ETH, BTC, SOL or TRX.
Relay
The payment is verified on its own chain — recipient and amount — and only then is the message handed to the mail relay.
