• draft_reply Sends messages · ~263 tokens
  Saves the text as the reply draft of a received email, from the address the email was written to (a brand address or the mailbox). needsIdentity: that address cannot send until the user verifies it in BumbleBox.

  Received emails BumbleBox classified as needing a reply and still in the inbox, newest first.

• send_reply Sends messages · ~282 tokens
  Replies to the sender of one received email, and only to them (no Cc, no Bcc, no attachment), from the address the email was written to.

  Moves one inbox email to its mailbox's trash when BumbleBox certifies it as noise (spam, newsletter, promotion, with a unanimous safety vote and no known contact or action word).
