Welcome to MailGate
Web3 Native Email — your inbox on-chain, your mail end-to-end encrypted, and spam priced out instead of guessed at.
MailGate is email, rebuilt so that you own the mailbox.
- Your account is an on-chain object on the Sui blockchain — not a row in a company's database that can be shut off.
- Your messages are end-to-end encrypted. The people running the service are mathematically unable to read your mail.
- Unknown senders pay a small toll to land in your inbox. Spam becomes expensive instead of free, and the money goes to you.
- You can hand a scoped AI agent access to your inbox without giving it your keys.
You don't need to understand blockchains, wallets, or cryptography to use it. This guide explains everything in plain language.

In the future
We're honest about today. A few things people expect from email aren't here yet:
- No mobile app. The website works well on a phone, but there's no installable iOS/Android app.
- No IMAP/POP3. You can't connect Apple Mail, Thunderbird, or Outlook to your MailGate inbox — use the web app.
- No calendar or contacts product. Contacts exist as a simple list; there's no calendar.
- Withdrawing earned tolls isn't live yet. You can see tolls accumulate; moving them out comes later.
