A guest didn't get their email

What to check

• The address on the booking. Open it on the book and read the email out. A typo is the usual answer, and there is nothing to fix in the system — the message went exactly where it was told.
• Their junk folder. A first message from a domain their mail provider has not seen before often lands there. Ask them to look, and to mark it not-junk so the reminder arrives properly.
• How the booking was made. A walk-in seated by staff has no email address and no confirmation to send. A booking taken over the phone only emails if someone entered an address.
• Whether it is a work address. Corporate filters are far more aggressive than personal ones, and the guest often cannot see what was quarantined.

What to do meanwhile

The booking is real whether or not the email arrived. It is on your book, the table is held, and the guest can turn up and be seated normally — an email is a receipt, not the reservation.

If they want the link that lets them change or cancel it themselves, fix the address on the booking first, then have them use it. If the address was simply wrong, correcting it is the whole fix.

Reminders follow the same path as confirmations. A guest who did not get one will not get the other, so treat a missing confirmation as a signal to ring them the day before rather than assuming the reminder will land.
