Why List Building is a Game-Changer for Rental Agencies

Customers Forget You Until They Need a Rental – Here’s How to Stay Top of Mind

When a customer needs to rent a vehicle, what’s the first name that pops into their head?

Chances are, it’s not yours.

It’s one of The Majors—those massive, household-name rental brands with billion-dollar marketing budgets, airport locations, and ads everywhere from billboards to travel websites. If they’re not thinking of The Majors, they’re probably doing a quick “car rental near me” search and booking with whatever rental agency is closest.

So where does that leave independent rental agencies like yours?

If you’re not staying connected with past and potential customers, you’re relying on hope—hoping they’ll remember you instead of a big-name competitor or the nearest alternative.

But hope isn’t a strategy.

That’s why list building is a game-changer for rental agencies. By collecting customer contact information and regularly staying in touch, you ensure that your brand is the first they think of when it’s time to rent again.

In this article, we’ll break down why list building is one of the smartest, highest-ROI marketing strategies for rental agencies and how you can start building a high-value email and SMS list to keep your vehicles booked year-round.

Why List Building is Essential for Rental Agencies

Unlike restaurants or retail stores, B2C vehicle rentals aren’t an everyday purchase. A customer might rent a car for a vacation, a work trip, a wedding, or an emergency vehicle replacement. That means:

🚗 They might need a rental once or twice a year, or even less.
🚗 They don’t think about your business until the moment they need a car.
🚗 When that moment comes, they’ll book with whoever is easiest to find.

If you aren’t actively reminding them of your agency, you’re relying on luck—and in a competitive market, that’s a risky strategy.

List building solves this problem by keeping your brand in front of customers between their rental needs, so they don’t forget you exist.

The Benefits of Building a Rental Customer List

A well-managed email and SMS list is one of the most powerful marketing assets your rental agency can have. Here’s why:

1. You Build Repeat Business (Instead of Always Chasing New Customers)

Acquiring a new customer is 5x more expensive than retaining an existing one. Yet most rental agencies focus all their marketing on getting new leads instead of keeping past customers engaged.

📌 With a customer list, you can:
  »  Send reminders to book their next rental.
  » Offer exclusive deals for repeat customers.
  » Upsell rental packages.
  »  Promote seasonal discounts for past renters.

Every time you reach out, you’re reducing the chances that they’ll book with a competitor next time.

2. Higher Profit Margins

Many rental agencies rely on third-party booking sites to bring in business—but those platforms take a huge commission from every booking.

When you own your own list, you don’t need to rely on expensive ads or third-party platforms—you have a direct channel to your past and potential customers. That means:

🚀 More direct bookings (less commission fees).
🚀 Lower customer acquisition costs.
🚀 Higher profit per rental.

3. More Last-Minute & Seasonal Bookings

Rental demand fluctuates. Some months, your fleet is fully booked—other times, cars sit idle.

With an email and SMS list, you can:

  »  Fill last-minute availability by sending out a flash sale to your list.
  »  Promote seasonal offers (e.g., holiday travel discounts).
  »  Encourage early bookings with exclusive offers.

This helps ensure steady bookings even during slower periods.

4. Increased Customer Lifetime Value (CLV)

CLV = The total revenue a customer generates for your business over their lifetime.

A customer who books once and never returns is worth a lot less than one who rents from you regularly.

By staying connected through email and SMS, you can:
  »  Turn one-time renters into repeat customers.
  »  Offer loyalty perks that incentivize them to book again.
  »  Encourage referrals (word-of-mouth marketing is powerful).

This increases the value of every customer, making your marketing efforts much more profitable.

How to Build a High-Value Rental Agency Customer List

Step 1: Set Up an Opt-In System

Customers must choose to join your list, so you need an opt-in system that makes it easy and enticing.

💡 Best Ways to Collect Customer Emails & Phone Numbers:
  »  During Booking: Add a checkbox for customers to opt-in when they book online or over the phone.
  »  At Pickup/Drop-off: Have a form or tablet where customers can enter their details to get future offers.
  » On Your Website: Add a sign-up form offering a discount or free upgrade for joining your list.
  » Via SMS: Use a text-to-join system (e.g., "Text ‘RENT’ to 55555 to get VIP rental deals").

🚀 Pro Tip: Offer an instant incentive to encourage sign-ups (e.g., “Join our VIP list & get 10% off your next rental”).

Step 2: Automate Follow-Up Messages

Once a customer joins your list, don’t just let them sit there—send an automated welcome message:

📩 Example Email:
"Hey [First Name], thanks for joining [Rental Agency Name]! As a VIP, you’ll get first access to exclusive discounts, special promotions, and free upgrades. Here’s 10% off your next rental – just use code VIP10 at checkout!"

This immediately engages the customer and increases the likelihood of their next booking.

Step 3: Send Value-Driven Content (Not Just Sales Emails!)

Your email and SMS list isn’t just for promotions—it’s also a way to build trust and engagement.

  »  Booking Reminders – “Planning a summer road trip? Book early for the best rates!”
  »  Exclusive Offers – “VIPs get first dibs: 15% off all SUVs this month!”
  » Travel Tips – “Best scenic routes for a weekend drive!”
  » Vehicle Spotlights – “Now available: Rent our new Convertibles!”

🚀 Pro Tip: The 80/20 Rule – 80% of your emails should be valuable/helpful, and 20% should be promotional.

Step 4: Use SMS for High-Impact, Time-Sensitive Offers

📱 SMS messages have a much higher open rate compared to emails). Use SMS for:

🚗 Flash Sales – “🚨 24-Hour Deal! Get 20% off your next rental – Reply YES to book!”
📆 Reminders – “Reminder: Your rental is due back tomorrow at noon.”
⭐ Review Requests – “Enjoy your rental? Leave us a review here: [Link]”

SMS is perfect for quick engagement and immediate action. But don’t overdo it and NEVER risk spamming people’s phones. The open rate is higher, but so are spam complaints and unsubscribes. Follow your country's anti-spam rules for SMS and email!
