Every conversation has a state.
Your inbox stops being a list sorted by date. Each thread is needs reply, waiting on them, I promised, FYI or done, set automatically when mail arrives and changed with one click.
- Promises tracked both ways: what you said you'd send, and what others owe you, with due dates and nudges.
- Views for Needs reply, Waiting, Promised and Today.
- Shared inboxes for sales@ and support@ with assignment, internal notes and “Ada is replying” warnings.
