Which emails go out, and changing their wording

Whether an email sends is set in Settings → Notifications → Automatic customer emails. Each automatic email has its own switch, and each saves the moment you switch it. The seven most shops change are listed first; Show all customer emails opens the rest. Turn off an important one, like Booking confirmation or Trip cancelled, and a warning appears under it.

On to start with: booking confirmation for online bookings, held seat released, trip confirmed, trip cancelled, itinerary, the trip reminder (24 hours before, or the hours you set beside Trip reminder), review request and reminder, and payment and refund receipts.

Off to start with: waiver reminder, balance reminder, chase missing diver details, after a missed trip, we miss you, and birthday.

A booking made in the office asks whether to email the customer, and sends nothing unless you choose to.

The wording is in Settings → Emails. Click an email, turn on Using your custom copy, edit the Subject Line and the body, and insert details like the customer's name with the chips. Preview shows it in light and dark mode, and Reset to Default undoes your changes. Some emails can be written differently for each activity.

Copies: You don't get a copy of every customer email. Open Show all customer emails and tick Send us a copy under the ones you want. They go to the address in Send copies to, or to your shop email when that is empty. Email that didn't arrive, in Settings → Delivery and opt-outs, lists every email from the last 30 days that didn't reach its person; the help article Delivery and opt-outs explains that page.

Customers can stop reminder emails: Trip reminders, trip confirmed, the itinerary, review requests and offers carry an Unsubscribe link at the bottom. The page it opens warns them that you are not responsible if they miss a check-in, and that they will still get emails about any balance. Booking confirmations, receipts, payment requests, balance reminders, waivers, cancellations and the messages you write yourself always reach them. Their client page then shows Reminder emails off, and an owner, admin or manager can press Turn reminders back on if the customer asks.
