SMS reminders for restaurants: definition and best practices

Automated text messages sent to guests before their reservation to confirm attendance and reduce no-shows.

SMS reminders are automated text messages sent to guests before their reservation to confirm attendance and reduce no-shows. For restaurants, SMS is the single most effective tool for fighting no-shows. Automated reminders reduce no-show rates by 30-50%, turning a $0.02 text message into hundreds of dollars in recovered revenue per week.

Key facts

Definition: Automated text messages sent before reservations to confirm or cancel
No-show reduction: 30-50% decrease with consistent reminders
Good benchmark: 80%+ confirmation rate from SMS reminders
Why it matters: The cheapest, most effective way to protect against no-shows

The quick definition

SMS reminders are text messages your reservation system sends automatically to guests before their booking. The typical flow includes a confirmation request, an easy way to cancel, and sometimes a follow-up if the guest does not respond. They work because text messages have a 98% open rate, compared to 20% for email.

Message Type	Timing	Purpose
Booking confirmation	Immediately after booking	Confirm details
Advance reminder	3-5 days before (for long lead times)	Early plan check
Primary reminder	24 hours before	Confirm or cancel
Day-of reminder	2-4 hours before	Final prompt

Why SMS reminders matter

They cut no-shows in half

No-shows cost restaurants thousands per month. SMS reminders are the easiest fix.

Scenario	No-Show Rate	Monthly Lost Revenue (100 covers, $50 avg)
No reminders	15-20%	$22,500-30,000
Email only	10-15%	$15,000-22,500
SMS reminders	5-8%	$7,500-12,000
SMS + deposit	2-3%	$3,000-4,500

They give guests an easy out

Many no-shows are not malicious. Guests forget, plans change, or they feel awkward calling to cancel. A text with a one-tap cancel option removes that friction. Cancellations are better than no-shows because they give you time to fill the table.

They improve the guest experience

A well-timed reminder shows professionalism. It tells guests you are organized and expecting them. Include helpful details like parking information or a link to the menu to enhance anticipation.

They generate real-time availability

When guests cancel via SMS, those tables immediately return to your available inventory. This creates last-minute booking opportunities you would not have without the reminder triggering a timely cancellation.

How to set up SMS reminders

Configure timing

Set up a sequence that matches your booking patterns:

Booking Lead Time	Reminder Sequence
Same day	2 hours before
1-3 days out	24 hours before
4-7 days out	48 hours + 4 hours before
1+ week out	5 days + 24 hours + 4 hours before

Write effective messages

Keep messages under 160 characters when possible. Include:

Restaurant name
Date and time
Party size
Confirm/cancel action
Link to modify (optional)

Good example: “Reminder: Table for 4 at The Oak, Fri Jan 10 at 7:00 PM. Reply YES to confirm or CANCEL to release your table.”

Bad example: “Dear Valued Guest, We wanted to reach out to remind you about your upcoming dining experience at The Oak Restaurant. We have you booked for a party of 4 on Friday, January 10th at 7:00 PM. We look forward to welcoming you.”

Set up follow-up rules

Decide what happens when guests do not respond:

Guest Action	System Response
Confirms	Mark confirmed, no further action
Cancels	Release table, add to availability
No response after 24h reminder	Send day-of reminder
No response after all reminders	Flag as high no-show risk

Best practices

Always include a cancel option

Make cancellation as easy as replying with a single word or tapping a link. The easier it is to cancel, the fewer no-shows you get.

Personalize when possible

Use the guest’s name and specific booking details. “Hi Sarah, see you Friday at 7pm” converts better than a generic template.

Do not over-send

Two to three messages per reservation is the sweet spot. More than that feels like spam and leads to opt-outs.

Track and measure

Monitor these metrics weekly:

Metric	Target
Delivery rate	95%+
Confirmation rate	80%+
Cancel via SMS rate	Track trend
No-show rate (post-implementation)	Under 5%

No-show - The primary problem SMS reminders solve
Booking lead time - Longer lead times need more reminder touchpoints
Reservation deposit - Combined with SMS reminders, deposits bring no-shows to near zero
Waitlist - SMS cancellations free tables for waitlisted guests

Frequently Asked Questions

Do SMS reminders actually reduce restaurant no-shows?

Yes. Automated SMS reminders sent 24-48 hours before a reservation reduce no-shows by 30-50%. The combination of a reminder plus an easy cancel/confirm option gives guests a low-friction way to honor or release their booking.

When should restaurants send SMS reminders?

The most effective timing is 24 hours before the reservation, with an optional second reminder 2-4 hours before. For bookings made more than a week in advance, an additional reminder 3-5 days out helps catch changes in plans.

How much do SMS reminders cost restaurants?

Most reservation systems include SMS reminders in their subscription. Standalone SMS services cost $0.01-0.05 per message. For a restaurant sending 3,000 reminders per month, costs range from $30-150, far less than the revenue saved from reduced no-shows.

What should a restaurant SMS reminder say?

Keep it short and actionable. Include the restaurant name, date, time, party size, and a confirm/cancel option. Example: "Hi Sarah, reminder: Table for 4 at Mario's, Friday 7pm. Reply C to confirm or X to cancel."

Do I need permission to send SMS reminders?

Yes. Guests must opt in to receive text messages. Most reservation systems handle this through the booking process. Always include an opt-out option and comply with local regulations like TCPA in the US.
