Fitness studio: the 6am cancellation reaches the coach

The setup

Owner Vera fans train@ out to six coaches. Each manages their own timetable from their own inbox.

How the mail flows

  1. A member cancels the 6am spin class at 5:10am.
  2. The coach holds the identical cancellation within minutes, still at home.
  3. The slot goes to the waitlist instead of running empty.
  4. train@ keeps the attendance-affecting record for billing disputes.

Why Sinka fits here

  • Early and late classes cover themselves — no office relay.
  • Coaches reply as themselves, so members learn names.
  • Cover coaches get copies for their week, revoked after.

Watch out for

  • Waitlist order must live in one place or the slot goes to the loudest, not the first.
  • Payment disputes need the thread — keep train@ CC'd on anything money-related.
