Invite one address, or up to 50 at once, from your own tools. They confirm the mail before any status update is sent. Claude, Cursor and Codex can send the same invitation.
A new address receives a confirmation mail and stays pending until the recipient opens the link. No status update goes out before that.
An address that already confirmed is left unchanged and gets no second mail. An address that is still pending is mailed again only when you ask for it, so importing the same list twice does not write to those people again.
The mail names the billing company on the account, or the status page title when no company name is set. How a script or an agent sends the invitation is in the API docs.
