WhatsApp Campaigns for Restaurants: The Complete Guide with Real Examples (2026)

• Email: 20% open rate, 2-3% response rate, very low cost per send
• SMS: 75-80% open rate, 5-10% response rate, low cost per send
• WhatsApp: 95-98% open rate, 25-40% response rate, low-to-moderate cost per send

WhatsApp combines the immediacy of SMS with the richness of email (you can send images, documents, buttons, lists) on a channel your customers experience as personal and close.

For most people, WhatsApp isn't just a messaging app — it's their primary way of communicating with other people. When a restaurant messages you on WhatsApp, it doesn't land in a spam folder or an overflowing inbox. It lands exactly where messages from friends and family land.

That creates a sense of closeness and trust that no other marketing channel can match.

WhatsApp lets you be extremely precise about timing. Sending a campaign about today's lunch special at 11:30am, right when people are starting to think about what to eat, has a completely different impact than that same message sitting in an email inbox at 9am.

This is probably the highest-ROI campaign type for any restaurant.

You have customers who came in once or twice and haven't been back in months. It's not that they didn't like it — they just forgot, life got busy, and they never had a concrete reason to return. A win-back campaign gives them that reason.

• Segment your database by last visit: customers who haven't booked in 45, 60, or 90 days
• Send them a personalized message with a specific reason to come back (a new menu item, the season, a limited-time offer)
• Include a direct booking button

"Hi [Name] 👋 We haven't seen you in a while and we miss you! We just refreshed our menu with new seasonal dishes we think you'll love. Feel like coming back? Book your table right here."

Typical response rate: 20-35%. A restaurant with 500 inactive customers can generate 100-175 additional bookings from a single campaign.

Tuesday and Wednesday nights are every restaurant's enemy. WhatsApp campaigns are perfect for driving traffic into those slots.

Identify the days and hours where you have spare capacity, then send a targeted campaign with an offer built specifically for those moments.

"[Name], any plans for tonight? We've got tables available, and this week we're offering 15% off on Tuesdays — just for you. Book before 6pm."

The discount doesn't need to be huge. It's the combination of personalization, scarcity (limited spots), and easy booking that actually converts.

Valentine's Day, Christmas, Easter, Mother's Day, a customer's birthday — every date is a business opportunity.

What sets a well-crafted WhatsApp campaign apart from a generic email is real personalization. If you know a customer celebrated their anniversary with you last year, you can message them on that date with something that genuinely surprises them.

"Happy birthday, [Name]! 🎂 We've been thinking of you here at [Restaurant]. As a gift, we'd love to offer you a free glass of cava if you come celebrate with us this month. Interested?"

"Valentine's Day is just 10 days away and tables are filling up fast. We've put together a special 4-course menu with wine pairing included. Should we save you a table?"

Opening your terrace? Launching a new menu? Bringing in a new chef? Every piece of news about your restaurant is a legitimate reason to reach out to your customers.

This type of campaign has a huge advantage: it doesn't feel like advertising. It's relevant news about a place the customer already likes.

"Our terrace is open! ☀️ This weekend we're opening our outdoor space, and we've put together a special summer menu. The first 20 people to book a terrace table get a welcome drink on us."

Google reviews are a restaurant's local SEO. The more you have, and the better they are, the more visible you become when someone searches for where to eat in your city.

WhatsApp is the perfect channel for requesting reviews because the response rate is extremely high, and if you send it a few hours after the visit, the message arrives while the experience is still fresh.

"[Name], thanks for coming in today ☺️ We hope you had a great time. If you have a moment, it would mean a lot if you left us a review on Google. It only takes 2 minutes and it means everything to us."

Between 15% and 25% of recipients leave a review when the message comes through WhatsApp, compared to under 5% when requested by email.

Beyond filling tables, WhatsApp lets you sell higher-value experiences: tasting menus, wine-pairing nights, private events, cooking classes, or gift packages.

"[Name], every December we run our wine-pairing nights with the sommelier, and spots go fast. We've expanded the format this year. Want us to send you the details before we announce it publicly?"

This type of campaign works especially well when you first ask whether they want the information — which prompts a reply — and then follow up with the details.

"Hi [Name] ✅ Your reservation at [Restaurant] is confirmed for [day] at [time] for [number] people. If you need to change it, just message us here. See you soon!"

"[Name], we're expecting you tomorrow 🍽️ You have a table at [time] at [Restaurant]. If anything changes, just let us know ahead of time. We can't wait to see you!"

"Hi [Name] 👋 We haven't seen you in a while and wanted to check in. We've refreshed our menu with seasonal dishes. Feel like coming back? Booking is quick and easy."

"[Name], eating out this week? We've got a table free tonight, and we just added a new dish to the menu we can't wait for you to try."

"Happy birthday, [Name]! 🎉 Everyone at [Restaurant] wishes you a wonderful day. As a little treat, we'll have a dessert on the house waiting for you if you come celebrate with us this month."

"Thanks for coming to [Restaurant] today, [Name] ☺️ We hope you had a great time. Could you leave us a review on Google? It only takes 2 minutes and it helps us so much."

• During the booking process: when a customer books online or by phone, you can ask for their WhatsApp number and capture consent in the form or verbally, with a record kept.
• With a QR code on the table: place it on the table or on the receipt, inviting customers to join your WhatsApp list in exchange for something of value (a discount on their next visit, the daily specials by WhatsApp, access to events).
• On social media: a link to a form or WhatsApp chat where customers opt in voluntarily.
• At the time of payment: the waiter can simply ask if they'd like to receive updates by WhatsApp.

• The customer must give explicit, specific consent — a generic "I accept the terms and conditions" doesn't count
• You must clearly state exactly what you'll use their number for
• The customer must be able to opt out easily at any time
• You must keep a record of that consent

At Bookline, consent management is built directly into the platform, so you stay compliant with European regulations automatically.

The free WhatsApp Business app is fine for handling one-on-one conversations, but it doesn't support mass sending or automation. If you try to run campaigns through the app, Meta can permanently block your number.

Sending messages to people who haven't given you permission is a GDPR violation, and it can lead to a wave of spam reports, which hurts your WhatsApp Quality Rating and can eventually get your number blocked.

Sending the same message to your entire contact list without segmenting is like handing out flyers on the street. A customer who only comes in for lunch doesn't need your corporate-dinner campaign. A regular who comes for date nights doesn't need to hear about your group menu.

WhatsApp is an intimate channel. If you send messages every week without real value, customers will stop reading them or, worse, block you. The general rule: one to two campaigns a month, always with relevant content.

Every campaign should have a single goal and a single possible action. If you mix "come for dinner" with "follow us on Instagram" with "leave a review," the customer doesn't know what to do and ends up doing nothing.

Yes. The free WhatsApp Business app doesn't support mass sending. To run campaigns, you need access to the API, which you can get through platforms like Bookline, an official Meta Business Solution Provider.

The cost depends on two factors: the platform you use and Meta's per-conversation fees. Each business-initiated marketing conversation typically costs around €0.08-0.10. For 500 contacts, that works out to roughly €40-50 per campaign — at a 10% conversion rate, that's 50 bookings for €50.

The recommendation is no more than 1-2 campaigns per customer per month. Relevance is the key: one well-segmented campaign a month beats four generic ones a week.

You shouldn't. Besides violating WhatsApp's terms of service, your personal number could end up permanently blocked. You need a business number set up through the API.

They need to be able to opt out easily, just by replying "STOP" or something similar. With the right platform, that process is handled automatically, and the contact is removed from your list for future campaigns.

Yes, although the type of campaign varies. A casual, daily-menu restaurant can use WhatsApp to announce the dish of the day and fill tables during slow hours. A fine-dining restaurant can use it to sell tasting menus and manage exclusive experiences. The channel works for everyone; the strategy just adapts.
