Confirmation email contains reference ID, service, date, time, timezone, host, and cancel link

Incomplete confirmation emails drive no-shows, double-bookings, and support tickets. When a customer gets an email missing the timezone, they join a 3:00 PM call at the wrong hour because they assumed their own timezone. Missing cancel links force them into account-login flows just to cancel, so they ghost instead — and the host loses the slot with no warning. A missing reference ID makes every support exchange a detective hunt. Content-integrity failures here feed directly into the no-show rate, the metric that kills booking-based businesses.

Update your confirmation email template to render all 7 fields and pair every time with an explicit timezone string. The cancel link must be a signed, tokenized URL that works without login — not a redirect to a generic account page. Edit src/emails/confirmation-template.ts:

export function confirmationEmailTemplate(booking: Booking, host: User) {
  return `
    <p>Ref: ${booking.reference_id}</p>
    <p>Service: ${booking.service_name}</p>
    <p>When: ${formatDateTimeWithTimezone(booking.start_time, booking.timezone)}</p>
    <p>Host: ${host.name}</p>
    <p><a href="https://yoursite.com/bookings/${booking.id}/cancel?token=${booking.cancel_token}">Cancel</a></p>
  `
}
