How to Bring Customers Back to Your Restaurant on Slow Days
Every restaurant owner knows the feeling.
Friday and Saturday are packed, but then Tuesday comes around and half the restaurant is empty.
Most restaurant owners immediately think they need more customers.
But I think they're looking at the problem the wrong way.
You already had the customers.
The problem is that they came into your restaurant, ate, paid, walked out the door — and you never collected a way to reach them again.
That's what I believe restaurants need to fix first.
Quick Answer
To bring customers back on slow days, start by building a permission-based customer list, then send timely, urgent text promotions the morning of your slow day. The combination of the right audience, a strong offer, and real urgency is what turns an empty Tuesday into a busy one.
Start Collecting Customer Information
The first thing I tell restaurant owners is to start building their own customer list.
Every day, people are walking through your doors. Instead of letting them leave without any way to reach them again, give them a reason to join your customer list.
One of my favorite ways to do this is with an immediate offer.
For example:
“Join our VIP list today and get two free tacos.”
Or:
“Sign up and choose a free quesadilla, beef enchilada, or two tacos on us.”
I like offers like these because they're tied to the individual customer.
If you offer 50% off the entire table's bill, you run into a problem: does everybody at the table sign up, or only the person paying?
Instead, give each individual person something valuable for joining.
They enter their name and phone number, properly opt in, and now you've turned a customer walking through your restaurant into someone you have a way to invite back.
Your Customer List Becomes More Valuable Over Time
This is where restaurant owners need to think long term.
Imagine you've owned a restaurant for 10 years.
Thousands and thousands of people may have eaten there during that time.
But if you never collected their information, how many of those people can you directly reach today?
Now imagine another restaurant spent those same 10 years consistently building its customer list. Maybe it now has 20,000 opted-in contacts.
When Tuesday and Wednesday are slow, that restaurant doesn't have to cross its fingers and hope an Instagram post gets enough views. It has an audience of past customers it can reach directly.
That's an asset that can grow month after month and year after year.
Give People a Reason to Come Back TODAY
Collecting the customer information is only the first part. You need a reason to bring those customers back.
And one of the biggest things I've learned working with restaurants is that the offer needs urgency.
Don't just say:
“Come in sometime this month and get 20% off.”
There's no reason for me to go today. I'll tell myself I'll do it later — and probably forget.
Instead:
“🚨 TODAY ONLY: Buy a large pizza and get a small pizza FREE.”
Now I have a reason to make a decision.
The offer is happening today. If I want it, I need to act.
That's why I like phrases such as “TODAY ONLY” and attention-grabbing elements like the siren emoji. You want the customer to immediately understand that this isn't an offer they can save for three weeks from now.
A Restaurant Brought in 40 Customers in One Day
One offer we've run for a restaurant was extremely simple:
Buy a large pizza, get a small pizza free.
That promotion brought in 40 customers in one day, and the restaurant sold out of pizza.
This is a real Sales Spike client result. I'm sharing it as a specific example, not as a guarantee that every restaurant will achieve the same result.
That's the power of combining the right audience with a strong offer and urgency.
But that doesn't mean every restaurant should run that exact promotion.
Other promotion ideas include:
- 30% off your entire order — today only.
- Buy two entrées, get a free appetizer.
- Buy a large item, get a smaller item free.
There isn't one magical restaurant promotion. Restaurant owners need to be creative, test different offers, and learn what their own customers respond to.
Send Your Promotion the Morning of the Slow Day
Timing matters.
If Tuesday is your slow day, I prefer sending the promotion Tuesday morning.
Why?
Because you're giving people enough time to plan around the offer.
If you send it the day before, they may see it and forget about it.
If you send it right before dinner, they may already have plans.
Sending it that morning gives them a chance to see:
“TODAY ONLY: Buy two entrées and get a free appetizer.”
Now they can think:
“Okay, maybe we'll go there tonight.”
Don't Blast Your Entire Customer List Every Week
If you've collected 2,000 phone numbers, that doesn't mean you should send the same promotion to all 2,000 people every Tuesday.
You're eventually going to annoy people and potentially increase opt-outs.
Instead, structure the list so an individual customer might receive a promotional message around once per month, depending on the restaurant's strategy and the customer's consent.
For example, with 2,000 eligible contacts:
- Week 1: Send the promotion to 500 customers.
- Week 2: Send it to another 500.
- Week 3: Another 500.
- Week 4: The final 500.
This lets the restaurant consistently promote its slow day without repeatedly blasting the same customers.
Automate Your Slow-Day Restaurant Marketing
This is where Sales Spike comes in.
Let's say a restaurant has 4,000 contacts, and Tuesday and Wednesday are consistently its slowest days.
The restaurant could configure a campaign that sends an offer to 500 different eligible customers every Tuesday and Wednesday at 10:00 a.m.
The campaign, schedule, and audience rules can be configured ahead of time so the system handles the recurring sends automatically.
The important part is rotating through the audience rather than repeatedly blasting the same customers.
Meanwhile, the restaurant continues collecting new customers.
That means the customer list can continue growing month after month and year after year.
You're not simply running another Tuesday promotion.
You're building a system for turning today's customers into future customers.
What I See Restaurant Owners Struggle With
I see restaurants work hard to fill tables on a Friday, then wake up Tuesday with no plan and no way to reach the people who already love their food. They post on social media and hope somebody sees it. The restaurants that fix this don't need a bigger advertising budget — they need a direct line to the customers they already earned.
Imagine Doing This for 10 Years
This is where the strategy becomes extremely powerful.
Imagine two restaurants have both been operating for 10 years.
Restaurant A never collected customer information.
Thousands of people have eaten there, but the restaurant has no direct way to reach most of them.
Restaurant B has consistently collected properly opted-in customer information for 10 years. Imagine Restaurant B eventually builds a list of 20,000 customers.
Now, when Tuesday and Wednesday are slow, Restaurant B has a large audience of previous customers it can invite back.
The longer the restaurant builds its customer list, the more valuable that list can become.
You Don't Have to Give Away Half Your Menu
Some restaurant owners hear this strategy and immediately think:
“I'm not giving my food away for free.”
That's completely fine. You don't have to.
One Sales Spike client is willing to offer 50% off a customer's first order for signing up because that owner believes acquiring the customer's information is valuable enough to justify the initial discount.
Another restaurant owner may never be comfortable doing that. And they shouldn't blindly copy someone else's offer.
Restaurant owners know their margins. They know their customers. They know their restaurant.
Sales Spike's job isn't to force restaurants to offer a specific discount. Sales Spike provides the platform for restaurants to build their customer list and the tools to reach those customers again.
The restaurant decides what offer makes sense for its business.
Test different promotions. See what customers respond to. Look at what actually brings people through the door. When you find something that works, you can continue using and improving it.
Stop Letting Customers Walk Out the Door Forever
A customer comes into your restaurant.
They order. They eat. They pay. Then they leave.
If you didn't collect any information from them, you're relying on that customer to remember you and decide to come back.
You can post on Instagram or Facebook, but you don't control whether every previous customer sees your post.
Building an opted-in customer list gives your restaurant a direct channel to people who already know your business.
So instead of waking up on a slow Tuesday wondering:
“How do I find more customers today?”
Start asking:
“How do I bring back the customers I already have?”
That's exactly what we built Sales Spike to help restaurants do: build their customer list, automate follow-up campaigns, and give restaurant owners the tools to bring past customers back when they need the business most.
Restaurant Owner Action Checklist
- Start collecting customer phone numbers with proper consent every single day.
- Offer something valuable to each individual customer for joining — not a vague table-wide discount.
- Build real urgency into every slow-day offer using phrases like “TODAY ONLY.”
- Send promotions the morning of the slow day so customers can plan around the offer.
- Rotate your audience so no single customer gets blasted every single week.
- Test different offers and keep what actually brings people through the door.
Frequently Asked Questions

I generally recommend an individual customer receives a promotional message around once per month. Rotate through your list in segments so you can promote consistently without overwhelming the same people.
What kind of offer works best for slow days?
Offers with real urgency work best — like “TODAY ONLY: buy a large pizza, get a small pizza free.” The customer needs a reason to act today instead of putting it off.

No. You decide what offer makes sense for your margins. Some owners offer a free item for joining; others never would. The important part is giving customers a clear reason to opt in.
