WhatsApp has a feature called Broadcast Lists that most restaurant owners don't know about or haven't thought to use for marketing. A broadcast list lets you send a single message to multiple contacts simultaneously — and crucially, each contact receives the message as if it were sent to them personally, not as a group message. Recipients reply to you privately. They don't see who else received the message.
For restaurants, this is one of the most direct and high-opening-rate marketing channels available. SMS open rates average around 98%. WhatsApp, which has a similarly immediate feel, performs comparably. Compare that to email (20–25% open rate) and social media (2–5% of followers seeing an organic post) and the attention advantage becomes clear.
What Are WhatsApp Broadcast Lists?
A broadcast list is a saved list of contacts to whom you send a single message simultaneously, with each recipient receiving it individually. It's not a group chat — no one can see who else received the message. Recipients who reply do so in a private one-to-one conversation with you.
The key limitation: a contact must have your number saved in their phone in order to receive broadcast messages from you. If they haven't saved your number, the message won't be delivered to them — it will show as sent but not received.
This limitation actually serves as a natural filter: the people who will receive your broadcasts are the people who cared enough to save your restaurant's number — a warm, engaged audience.
Setting Up Your Restaurant Broadcast List
Step 1: Ensure you're using WhatsApp Business (the dedicated business version of WhatsApp, available free in the app stores).
Step 2: Build your contact list. Export your reservation history and manually add guest phone numbers. Give each contact a label like "Dining Guests" or "Newsletter List." Ask guests who contact you via WhatsApp if they'd like to receive your weekly updates — add those who say yes.
Step 3: Create a Broadcast List. In WhatsApp Business, tap the three dots (menu) → New Broadcast → select contacts from your list. You can create multiple broadcast lists for different segments (e.g., one for regular guests, one for private dining enquiries, one for loyalty programme members).
Step 4: name the list and save it. You're ready to send.
What to Send in Restaurant Broadcast Messages
Broadcast messages work best when they feel personal and timely rather than like marketing emails. The format should match how you'd message a friend about something happening at the restaurant.
Weekly menu updates: "Hi! Just wanted to let you know — our weekend menu this Saturday includes a new grilled sea bream that just came in from Cornwall. Let me know if you'd like a table. 😊" (Note: use your natural voice, not formal language.)
Event announcements: "Hi — quick heads up that we're hosting a small wine dinner on the 18th, six courses and six pours. Seats are limited and I thought of you. Let me know if you're interested and I'll send the details."
Last-minute availability: "Just had a cancellation for tonight — we have a table for 2 or 4 at 8pm if you fancy dinner. First come first served on this one!"
Special occasion reminders: "Mother's Day is coming up — we're putting together a special Sunday menu and we'd love to have you. Shall I hold a table?"
Post-visit thank you: "Really great to have you in last night — hope you enjoyed the new menu. Would love to see you again soon."
These messages have dramatically higher engagement than equivalent email broadcasts because they arrive in a messaging app the recipient checks constantly, in a format that feels like personal communication.
GDPR and WhatsApp Marketing Compliance
In the EU and UK, sending marketing messages via WhatsApp is subject to the same GDPR principles as email marketing: you need the recipient's consent to send them commercial communications. This means:
- Never add people to your broadcast list without their knowledge
- Get explicit consent: "Would you like to receive our weekly menu updates via WhatsApp?" or a sign-up form where they opt in
- Make it easy to opt out: "Reply 'STOP' at any time to be removed from our list"
- Don't send broadcast messages to people who have only contacted you for a reservation — that's a transactional interaction, not a marketing opt-in
In practice, the permission issue is often handled naturally by the WhatsApp number requirement — people only have your number if they gave you theirs voluntarily, often in a context where they're likely to welcome updates.
Segmenting Your Broadcast Lists
One broadcast list isn't enough once your contact base grows. Create separate lists for different segments:
Regular guests: your most frequent visitors, who will appreciate weekly menu updates.
Private dining enquiries: people who have inquired about events — send them event-specific broadcasts.
VIP or loyalty members: a special list for your most loyal guests who get early access to events or special offers.
Delivery/takeaway customers: a separate list for customers who primarily order online — send them delivery promotions rather than dine-in content.
Segmented messages have higher relevance and better engagement than one-size-fits-all broadcasts.
Frequency and Volume
WhatsApp broadcasts work because they feel like personal messages. Abuse that familiarity by messaging too often, and guests start treating your number as spam — or worse, blocking it.
For a restaurant, one or two broadcasts per week is the sustainable maximum for most audiences. Weekly is ideal: a Sunday or Monday message setting up the week's menu or highlighting the upcoming weekend special reaches guests when they're planning their week.
WhatsApp Business vs WhatsApp Business API
The free WhatsApp Business app allows broadcast lists of up to 256 contacts per list. For restaurants with larger contact bases, WhatsApp Business API (accessed through approved providers) removes the broadcast limit and adds automation capabilities — including automated booking confirmations, post-visit follow-ups, and menu delivery via chatbot.
WhatsApp Business API requires setup through an approved solution provider and typically costs £50–£200+ per month depending on message volume and provider. It's worth considering for restaurants sending high volumes of reservations or takeaway confirmations.
Frequently Asked Questions
Will recipients know they're on a broadcast list?
No. Recipients receive the message exactly as if you had sent it to them personally. There's no label or indicator that the message was broadcast to multiple people.
Can I use WhatsApp Broadcast for a restaurant with multiple locations?
Create separate WhatsApp Business accounts for each location and maintain separate broadcast lists per location. Contact lists should be location-specific — sending a London restaurant's Saturday menu to someone in Manchester is irrelevant and annoying.
What happens if someone replies to a broadcast message?
Their reply comes through as a private one-to-one message with you. This is an advantage: it opens a direct conversation that can lead to a reservation.
