bMail: pay for a stamp only when it’s delivered
bMail pays for your stamp only once a letter is delivered. Agreements live in your inbox, signed with your wallet, and a letter can carry a meeting invite.
Stamps paid on delivery
Your stamp is signed but held until the letter is accepted, then sent. A letter that can’t go costs nothing, and a retry reuses the same stamp, so you never pay twice.
Agreements
Agreements have their own box in bMail. You sign with your card signature and your wallet’s identity key, and the signed copy gets a seal receipt on chain. Anything that needs you shows Review & sign.
Meeting invites
A letter that links a bChatX room shows Join meeting from ten minutes before it starts. The notification opens the room if the meeting is live, or the letter if not. You can turn these off in Settings › Notifications.
Your name works there too
Your $name also works as name@bmailx.com.
