The email draft: a line with mail: becomes a short draft to the @Name or the address in the line, with subject and text only from what you wrote. Nothing is sent by itself: you check it, then open it in your own mail app or send it via Axsuro, and replies come to you. Axsuro remembers the address for the name.
The summary: "Send summary" emails the meeting with its notes, decisions and tasks (who, by when) to everyone who was there and to any address you add. The client needs no account and only sees this one meeting. You can add a few words at the top and look at a preview first.
When the client goes quiet: if a wait: entry is still open after five days, your phone gets a notification with a short reminder, ready to send. It only goes out when you tap.
