Booking reminders: how many, and how late

Booking reminders are the cheapest, gentlest and most effective way most restaurants have to cut no shows. The most common reason a guest fails to arrive is not that they changed their mind, but that they forgot, or that their plans changed and cancelling felt like more effort than staying away. A short message at the right moment fixes both: it reminds the forgetful guest and gives the guest whose plans have changed an easy way to say so.

That sounds simple, and in principle it is. In practice, the details decide whether reminders work. A reminder sent too early is forgotten by the day. A reminder sent too late arrives after the guest has already decided not to come, or too close to the booking for you to fill the table. A reminder without an easy way to cancel reminds guests of a booking they will not keep and does nothing else. And too many reminders train guests to ignore them.

This guide covers the details: how many booking reminders to send, the reminder timing that works for different kinds of booking, what the message must say, how the confirmation and the reminder work together, and how to tell whether your reminders are working.

A reminder has two jobs, and both matter.

The first is to remind. Bookings made days or weeks in advance slip out of memory, especially when the guest booked on behalf of a group or as one of several plans. A reminder brings the booking back to mind at a point when the guest can still act on it.

The second is to make change easy. A reminder that includes a simple way to change the time, change the party size or cancel turns a guest whose plans have changed from a likely no show into a cancellation you can resell. This second job is the one most reminders neglect, and it is often the one that does most of the good.

It is worth being clear about what happens without reminders, because the cost is easy to underestimate. A guest who booked two weeks ago for a Thursday dinner may simply forget. A guest whose friend cancelled may decide not to come but never think to tell you. A guest who booked three places for the same evening, intending to choose later, will choose one and abandon the other two without a word. None of them is being rude on purpose. The booking just slipped out of view.

Each of those becomes an empty table that the kitchen prepped for, the rota staffed for and the host held for. On a quiet night, that costs the preparation and the labour. On a full night, it also costs the guest you turned away because the diary said the room was full.

A reminder does not stop every one of these, but it catches a large share of them at the point where something can still be done. That is why it is the first measure worth putting in place, before any policy, fee or deposit.

For most bookings, one reminder is enough. A single, well-timed message reminds the guest, gives them a way to cancel, and does not become noise.

A second reminder can help in specific cases: large parties, peak services where an empty table is expensive, bookings made a long way in advance, and special dates. For these, a reminder a few days before and a short one on the day can both earn their place.

More than two is rarely helpful. Guests who receive several reminders for one booking start to ignore them, or unsubscribe, which makes every future reminder less effective. If you are tempted to send a third reminder, it is usually a sign that a different measure, such as a confirmation call for large groups, would work better.

Reminder timing matters more than the channel or the wording. The reminder needs to arrive early enough that a guest who cannot come has time to tell you, and you have time to resell the table, but late enough that the booking is still fresh in mind.

For most dinner bookings, a reminder around a day before works well. It arrives at a point when the guest knows whether their plans still hold, and it leaves you most of a day to fill a cancelled table from the waitlist or with walk-ins.

For lunch bookings, a reminder the evening before or early on the morning of the booking usually suits, because lunch plans are often made and changed at shorter notice.

For bookings made far in advance, a reminder about a week before can help, followed by the usual reminder around a day before. The first reminder catches plans that have changed over weeks; the second catches the last-minute changes.

For same-day bookings, a reminder is usually unnecessary, because the booking is already fresh. A clear confirmation does the job.

Whatever schedule you choose, avoid sending reminders late at night or very early in the morning. A message that wakes a guest at six in the morning does not make them more likely to come; it makes them less likely to book with you again. Send reminders during normal waking hours in the guest's local time.

A reminder should be short and complete. It needs:

Leave out anything that turns the reminder into a marketing message. A booking reminder is a service message, and guests trust it because it is about their booking. Filling it with offers and newsletters makes it look like marketing, which makes it easier to ignore.

The most important part of a reminder is the link to change or cancel. Without it, a guest whose plans have changed has to find a phone number, call during service and wait while someone looks up the booking, and many will not bother. With it, they can tell you in seconds. Every cancellation that comes through that link is a table you can offer to someone else, instead of a table that sits empty at eight o'clock.

The reminder is the second message a guest receives. The first is the confirmation, sent when the booking is made, and it sets the tone. Confirming a booking properly makes the reminder work better.

A good confirmation repeats everything the reminder will: the venue, the date and time, the party size and the address. It explains the cancellation policy, if there is one, in plain language. It includes the same link to change or cancel. And it reads like a table being kept for the guest, not an automated receipt.

The confirmation is also the moment to check that the guest's contact details are right. A booking with a mistyped email address or phone number cannot be reminded at all. Verifying the address at the time of booking, for example with a short code the guest enters before the booking is confirmed, removes that problem at source.

Reminders can go by email, by text message or through a messaging app. Each has strengths.

Email is reliable, carries more information, and suits confirmations and reminders that include directions or a menu. It can be missed if it lands in a promotions folder, so it matters that reminders are sent properly from a recognised sender. Large email providers publish guidance for senders, such as Google's email sender guidelines, and following it helps service messages reach the inbox.

Text messages are read quickly and suit short, same-day reminders. They cost more per message and are more intrusive, so they suit the reminders that matter most.

Whichever channel you use, keep service messages and marketing apart. Booking reminders are about a booking the guest made; sms marketing and email campaigns are about promotions the guest has agreed to receive. Mixing the two, or using a reminder as a way to send offers, erodes trust in both, and in many places it also breaks the rules about marketing consent.

Tone matters. A reminder that reads like a warning, such as "failure to attend will result in a charge", sets the wrong mood for a meal. A reminder that reads like a host looking forward to seeing you works better and still gets the message across.

Compare two openings. "Reminder: your reservation at 8pm tomorrow. Cancellations must be made 24 hours in advance." And: "We're looking forward to seeing you tomorrow at 8pm. If your plans have changed, you can update or cancel your booking here." Both remind; the second also invites the guest to tell you, which is what you need.

Different bookings deserve slightly different reminders.

The right schedule depends on how your guests book and when they decide.

A neighbourhood restaurant with mostly local guests booking a few days ahead usually does well with a single reminder the day before. Guests live nearby, plans are simple, and one nudge is enough.

A destination restaurant with bookings made weeks or months in advance benefits from two reminders: one about a week out, when longer-range plans are confirmed or abandoned, and one the day before. Guests travelling to visit are also more likely to need directions, parking information and the time the kitchen closes.

A hotel restaurant often takes bookings from guests who are already on site, sometimes the same day. Here, the confirmation does most of the work, and a short reminder an hour or two before is reasonable, because guests are nearby and plans change by the hour.

A busy bar or casual venue that takes bookings for groups often benefits from a reminder to the organiser a few days ahead, asking them to confirm numbers, because a group of ten that arrives as six leaves the venue overstaffed and under-seated.

Here is an illustrative before and after for a restaurant that started sending reminders. The figures show how to read the results, not what to expect.

The headline is not that empty tables disappeared. It is that guests who would have stayed away silently told the venue instead, and the venue could do something about it. That shift, from no show to cancellation, is what a good reminder does.

Measure three things by service, before and after changing your reminders: the no show rate, the late cancellation rate and the seated rate. Reminders are working when no shows fall, late cancellations rise and seated covers hold or rise. If no shows fall but seated covers fall too, the reminders may be prompting cancellations you cannot fill, which is a sign that your waitlist and walk-in handling need attention. Our guide to measuring your no show rate covers the calculation.

Many venues still take a large share of their bookings by phone, and those bookings deserve reminders just as much as online ones. The difficulty is that a phone booking often ends without a working email address or a confirmed mobile number, because the person answering the phone was in the middle of service and wrote down only a name and a time.

Fix it at the moment of the call. Train the team to take a contact address or number for every booking, read it back, and tell the guest that a confirmation and a reminder will follow. Then enter the booking in the same system as online bookings, so it receives the same confirmation and reminder automatically. A phone booking entered this way behaves like any other booking; one written on a pad behind the bar cannot be reminded at all.

If you run more than one venue, keep the reminder logic consistent while letting each venue's name and details lead. Guests who book at two of your venues should receive messages that feel like they come from the same group, sent at similar times, with the same kind of cancellation link. Consistency builds trust: guests learn what to expect, and they learn that the link really does work. Review the timing for each venue separately, though, because a lunch-led café and a late-night bar will not suit the same schedule.

Reminders are one lever among several, and they work best alongside the others: verified contact details, a clear confirmation, easy cancellation, a live waitlist, and deposits only where a no show is genuinely expensive. Our guide on how to reduce no shows without annoying guests sets out the full sequence, and our guide to what a no show costs helps decide how hard to push on each service.

In servearound, guests who book online verify their email with a six-digit code before the booking is confirmed, so every booking can be reached. A reminder goes out as many hours before the booking as you choose, and both the confirmation and the reminder carry a link that lets the guest change or cancel their own booking, so the change lands in your diary instead of in a voicemail. A booking can also be postponed to another date or time without cancelling and starting again.

The reservations report in Analytics shows no show, cancellation and seated rates by meal period, source and party size, so you can see whether your reminder timing is working. Marketing is kept apart: Campaigns writes only to guests who opted in, with unsubscribe handled on the guest's own record. See the reservations module for the full booking flow.

Almost every booking made more than a day in advance. Same-day bookings rarely need one, because a clear confirmation is enough.

For large parties and special dates, a personal call or message can be worth it. For ordinary bookings, an automated reminder with a cancellation link is faster and just as effective.

Usually, yes, and that is a good sign. Cancellations you know about can be resold; no shows cannot.

You can, but do not cancel a table automatically because a guest missed the message. Follow up with a person, or simply rely on the cancellation link.

During normal waking hours, in the guest's local time, and ideally at a similar time each day so that guests learn to expect them.

If you have one, yes, briefly and warmly. A single line such as "if you can't make it, please let us know by midday so we can offer your table to someone else" explains the policy as a courtesy rather than a threat, and most guests respond well to being asked that way.

Regulars rarely forget, but a reminder still helps them change plans easily, and most do not mind it. If a regular asks not to receive reminders, note it on their profile and respect it.

The table should become available immediately in your diary, so the host can offer it to the waitlist or to walk-ins. A cancellation link that only sends an email to an inbox nobody reads during service loses most of its value.

A link to the menu can be helpful, especially for first visits, but keep it secondary. The reminder's main jobs are to remind and to make change easy.

Booking reminders work when they arrive at the right time and make change easy. Send one reminder for most bookings, around a day before dinner and the evening before or morning of lunch, with a second only for large parties, peak services, long lead times and special dates.

Keep the message short and complete, include a single link to change or cancel, keep marketing out of it, and avoid antisocial hours. Measure no shows, late cancellations and seated covers by service, and a well-timed reminder will turn many silent no shows into tables you can fill.
