SMS for restaurants: how to text customers and staff the right way

Restaurants use SMS for two distinct jobs: keeping customers coming back and keeping operations running. A reservation reminder sent 24 hours out reduces no-shows. A shift confirmation the morning of a busy Friday prevents a scramble at 5 PM. A promotional text to opt-in regulars fills a slow Tuesday. Each of these is a message that actually matters to the person receiving it — and that's the only kind worth sending.

What can restaurants use SMS for?

Restaurant SMS falls into two categories with different rules, consent requirements, and costs. Customer-facing messages (promotions, reservation reminders, loyalty offers) require prior express written consent. Staff-facing messages (shift confirmations, schedule changes, emergency closures) require a lower consent bar but still require opt-in. Getting this distinction right is the foundation of a compliant program.

How do reservation reminder texts work?

A reservation reminder sent 24 hours before a booking consistently reduces no-shows. The message identifies the restaurant, confirms the date, time, and party size, and gives the guest a way to cancel or modify — ideally with a phone number or link rather than just a reply keyword. Guests who receive a confirmation and don't respond are far more likely to show up than those who don't hear from you at all.

A standard reservation reminder sequence looks like this:

1. 24-hour reminder. Confirm the reservation details. Include the name, date, time, party size, and a way to reach you. Keep it under 160 characters if possible.
2. Same-day reminder (optional). For high-value reservations or during peak seasons, a same-day text sent 2–3 hours before the reservation adds a second touchpoint without feeling intrusive.
3. No-show follow-up (optional). For restaurants that hold tables, a polite follow-up after the reservation window closes keeps the door open for rescheduling without burning the relationship.

Example reservation reminder:

Grove Table: Hi [First Name], your reservation for [party size] is confirmed for [date] at [time]. Need to change it? Call us at [phone] or reply CANCEL. Reply STOP to opt out.

How should restaurants use SMS for promotions?

Promotional SMS works when it reaches people who asked for it, carries something worth their time, and doesn't arrive so often that unsubscribing feels like relief. A restaurant's regulars are an asset. How you text them determines whether they stay that way.

Three promotional uses that consistently perform well for restaurants:

• Off-peak offers. A text on a slow Tuesday afternoon — "Tonight only: half-price apps from 4–6 PM, show this text" — fills tables that would otherwise sit empty. The message has immediate value and a clear expiration.
• New menu announcements. Regulars who care about your food want to know when something new is on the menu. A short text with a link to the new items rewards people who opted in to hear from you.
• Loyalty rewards. "You've visited 10 times — your next dessert is on us" is the kind of text that earns goodwill with a customer who's already demonstrated they like you.

The right frequency is usually once or twice a month for most restaurants. More than that, and opt-out rates climb. Fewer than once a month, and the program loses momentum. Test your cadence against your opt-out rate — if it starts rising, slow down before you lose the list you built.

How do restaurants collect SMS consent from customers?

Promotional SMS requires prior express written consent, which is a clear opt-in that occurs before the first marketing message. Buying a list of phone numbers and texting people who've never heard of your restaurant is not compliant and will get your messages filtered by carriers. The good news is that restaurants have natural opt-in touchpoints that most other businesses don't.

Where restaurants collect consent most effectively:

• Reservation forms. A checkbox at the bottom of your online reservation form: "Text me exclusive offers and updates from [Restaurant Name]. Message and data rates may apply. Reply STOP to opt out." This is the highest-intent moment because someone actively booking a table is your most engaged potential subscriber.
• Paper sign-ups at the hostess stand or tables. A simple card: "Text JOIN to [number] for exclusive offers." Works well for walk-in-heavy concepts.
• WiFi opt-in. If you offer guest WiFi, the landing page is a clean place to collect consent before granting access.
• Loyalty program enrollment. If you have a loyalty program, build SMS consent into the sign-up flow. Customers who join a loyalty program have already signaled they want a relationship with you.

Staff-facing consent is simpler. Including SMS contact in your onboarding paperwork, with a clear explanation of the kinds of messages employees will receive and how to opt out, satisfies the requirement and sets expectations before anyone's first shift.

How do restaurants use SMS for staff communication?

Staff SMS solves a specific problem that every restaurant manager knows: hourly employees are harder to reach than salaried ones. They don't check email. Group chats get noisy. Calls go unanswered. A text gets read.

The highest-value staff use cases:

• Shift confirmations. Send a confirmation the morning of a shift with the start time and any notes: "Hi [Name], your shift starts at 4 PM today. Side work starts at 3:45. Reply YES to confirm or call [manager phone] if you can't make it."
• Open shift alerts. When someone calls out, a text to your available pool fills the gap faster than individual calls. "Open shift tonight, 5 PM to close. First to reply YES gets it. Text [manager] to confirm."
• Emergency closures and weather. If you're closing early or opening late due to weather or a system failure, a mass text to all staff eliminates the phone-tree scramble.
• Policy or menu updates before service. A quick pre-shift text with tonight's featured items or a new menu change ensures every front-of-house employee walks in informed.

What does restaurant SMS compliance require?

Two regulatory frameworks govern restaurant SMS: the TCPA (Telephone Consumer Protection Act), which sets federal consent requirements, and CTIA guidelines, which set carrier-level standards for message content and opt-in processes. Non-compliance doesn't just create legal risk — unregistered or non-compliant senders get filtered by carriers, meaning your messages don't arrive.

The four things every restaurant SMS program needs:

1. 10DLC registration. Any business sending text messages through a 10-digit local number must register with The Campaign Registry. This verifies your business and your use case with carriers. Unregistered traffic gets blocked. Text-Em-All handles registration on your behalf at no additional charge, with most approvals processed within one to two business days.
2. Clear opt-in language. Every opt-in touchpoint must identify your business, explain the kinds of messages the subscriber will receive, note the message frequency, include opt-out instructions ("Reply STOP to opt out"), and include a note that message and data rates may apply.
3. Immediate opt-out honoring. When someone replies STOP, they stop receiving messages. No exceptions, no delays. Your platform should handle this automatically.
4. Separate lists for customers and staff. Marketing messages to customers require express written consent. Operational messages to staff require express consent. Mixing these lists creates compliance exposure and degrades the relevance of both programs.

Which SMS features does your restaurant actually need?

• If you take reservations: Set up an automated reservation reminder sequence. One message 24 hours out reduces no-shows without adding work to your front desk team.
• If you have a loyal regular customer base: Build an SMS list at the point of reservation or loyalty enrollment. Even a small opted-in list is worth more than a large, non-compliant, purchased one.
• If you have 10+ hourly employees: Staff SMS pays for itself the first time it fills an open shift without a 45-minute phone tree. Set it up before you need it.
• If you run a high-volume walk-in concept: Waitlist and order-ready texts don't require marketing consent — they're transactional. Start there and layer in marketing later once you've built the operational infrastructure.
• If you run multiple locations: Keep each location's contact list separate. A guest at your downtown location opted in to hear from that location, not from your entire restaurant group.

Frequently asked questions about SMS for restaurants

Can restaurants text customers without their permission?

Not for promotional messages. The TCPA requires prior express written consent before sending marketing texts. Sending promotional SMS to customers who haven't opted in can result in carrier filtering, legal liability, and damaged customer relationships. Transactional messages, such as order-ready notifications and waitlist updates, offer greater flexibility because the customer initiates the interaction, but building an opt-in list remains the right foundation.

How many SMS messages should a restaurant send per month?

For promotional messages, one to two per month is the range where most restaurants see strong engagement without elevated opt-out rates. Staff operational messages can be sent as needed. A shift confirmation the morning of every shift is appropriate and expected. If your promotional opt-out rate is climbing, reduce frequency before changing content.

What's the difference between a reservation reminder and a promotional text?

A reservation reminder confirms information the customer already provided and is considered an informational message. A promotional text offers something (a discount, a new menu item, a loyalty reward) to drive behavior. They require different consent levels and should come from separate lists. A customer who gave their number to confirm a reservation hasn't consented to receive your weekly specials.

Do restaurants need to register their phone number before texting customers?

Yes. Any restaurant sending texts at volume through a 10-digit number needs 10DLC registration through The Campaign Registry. This is a carrier requirement, not optional. Unregistered numbers are filtered, meaning your messages won't reach customers even if everything else is correct. Registration takes one to two business days and is handled by your SMS platform, like Text-Em-All.
