How to Send Your Daily Specials to Customers Automatically (With a QR Code Sign-Up)
A QR code on your counter. Customers scan it, join your list, get your daily specials automatically. You type one message and hit send. No app developer, no monthly agency fee, no algorithm deciding whether your post gets seen.
Here’s how three types of small businesses set this up in an afternoon — a café, a food truck, and a service business where customers book a specific person.
The Problem Worth Solving
Most cafés and food trucks have regulars who’d love to know about today’s special. But email newsletters are too formal and slow for “today’s pulled pork banh mi is $14.” Social posts get buried. SMS gets expensive fast. So most owners just don’t tell anyone.
The fix is a direct list: customers opt in, you send direct, they get it instantly. The QR code is just the sign-up mechanism.
The Setup (Works for Both)
Four steps. One afternoon. No code required.
Step 1: Create a sign-up form
Use Google Forms (free). Ask for a name and phone number or email: whichever matches how you plan to send. Keep it to two fields. The longer the form, the fewer people finish it.
Step 2: Choose your delivery channel
| Channel | Cost | Best for |
|---|---|---|
| Telegram channel | Free | Cafés, food trucks, retailers |
| WhatsApp broadcast | Free (manual) or ~$50/mo (API) | Businesses where customers already use WhatsApp |
| Email (MailerLite) | Free up to 1,000 subscribers | Longer offers, weekly specials |
For most small businesses: Telegram channel. Free, instant, no algorithm filtering who sees it. Frank Arrigo built exactly this kind of location broadcast automation for MelbWeekendAlerts in a single afternoon: same principle, different use case.
Step 3: Generate your QR code
Take the URL of your Google Form and paste it into a free QR code generator, qr.io or qrcode-monkey.com both work well. Download the image, print it, stick it on your counter, table tent, window, or the side of your truck.
Step 4: Automate the sign-up
When someone fills out the form, you want them added to your list automatically. Set up a Zapier or Make automation: new Google Form response → add subscriber to your Telegram channel invite or MailerLite group. One-time setup, about 30 minutes, free on both platforms’ basic tiers.
What It Looks Like in Practice
The Café
A QR code sits next to the register. Regulars scan it while they wait for their order. They join a Telegram channel with 200 other locals. Every morning at 8am, the owner types one message:
Today’s special: Pulled pork banh mi $14. Grab one before 2pm 🥖
Two hundred people get that notification on their phone. Some come in specifically because of it. No algorithm, no boosted post, no $200 Facebook ad.
The Food Truck
The QR code is on the truck itself. Fans scan it at the first visit and join the list. Every day when the truck parks, the owner sends one message:
We’re at Docklands today: corner of Bourke and Collins. Open 11–2. Today’s special: Korean fried chicken $13 🌶️
The regulars who missed last week’s spot come back. New customers scan the QR on the truck and join for next time. The list grows without any effort.
The Hairdresser
Regulars don’t just want a haircut: they want their person. The stylist who knows their hair, remembers how they like it, and doesn’t need a 10-minute catch-up before picking up the scissors.
A QR code on the mirror or at the front desk. Customers scan it and join a list tied to a specific stylist. When that stylist has a cancellation, gets new availability, or is back from leave:
Hey. Jess has a spot open this Thursday at 2pm if you’re keen. First in. Reply to this message or book at [link].
The slot fills in minutes from people who actually want it. No awkward cold calls, no empty chair. Works for barbers, personal trainers, beauty therapists, physios: anyone where the relationship is with a specific person, not just a service.
What Does It Cost?
| Tool | Cost |
|---|---|
| Google Forms | Free |
| QR code generator | Free |
| Telegram channel | Free |
| Zapier (free tier) | Free up to 100 tasks/month |
| Make (free tier) | Free up to 1,000 operations/month |
| Total to start | $0/month |
If your list grows past a few hundred active subscribers, you might eventually look at a paid plan on Make or a WhatsApp Business API: but you’ll know when you’re there.
Use AI to Write the Messages
Once the system is running, the daily message itself takes 30 seconds with AI. Just tell ChatGPT or Claude what today’s special is:
Write a short, friendly message for our Telegram channel announcing today’s lunch special: grilled salmon $18. Keep it under 30 words, add an emoji.
It writes it. You review it. You send it. Done.
What You Need to Get Started
- A Google account (for Forms)
- A Telegram account (for the channel)
- A free Zapier or Make account (for the automation)
- A printer and some laminating pouches
That’s it. The whole thing can be live before lunch.
