9 Ways to Use QR Codes to Grow Your Email List

If you're looking to grow your email list faster, QR codes might be the secret weapon you've been overlooking. With mobile devices glued to our hands, scanning a QR code is now second nature—and it’s a simple, touchless way to guide users straight to your email sign-up form.

According to Statista, over 89 million smartphone users in the U.S. scanned a QR code in 2023, and that number is expected to surpass 100 million by 2025. From packaging and print ads to social media and in-store signage, QR codes are everywhere—and savvy marketers are using them to capture leads where people least expect it.

Here are 9 powerful ways to use QR codes to grow your email list—plus helpful hints to make each tactic even more effective.

1. Add QR Codes to Printed Flyers and Brochures

Why it works: Print materials are tangible and still have a place in local marketing. A QR code makes them interactive and measurable.

Pro Tip:
Create a trackable landing page specifically for each campaign so you can monitor conversions. Use a short call to action like “Scan to Get 10% Off Your First Order” to boost urgency.

Bonus Stat:
70% of consumers say direct mail feels more personal than online interactions (Source: USPS).

2. Use QR Codes on Product Packaging

Why it works: The unboxing experience is a prime opportunity to deepen the customer relationship.

Helpful Hint:
Send customers to a thank-you landing page with an exclusive offer, how-to content, or a free digital download. Include language like “Enjoy your purchase? Get more tips, tricks, and deals straight to your inbox.”

Stat to Know:
66% of consumers say they’re more likely to buy from a brand that delivers personalized experiences (Source: Salesforce).

3. Display QR Codes at Checkout Counters

Why it works: Shoppers already trust your brand if they’re making a purchase—capitalize on that moment.

Pro Tip:
Use signage with a simple incentive: “Scan to Get $5 Off Your Next Visit!” Keep the opt-in form short—just name and email.

Pro Tip:
Test A/B variations with different incentives (e.g., discount vs. loyalty program entry) and track which one performs best.

4. Incorporate QR Codes into Event Materials

Why it works: Events are full of qualified prospects who are already interested in your niche.

Helpful Hint:
Add a QR code to your presentation slides or booth signage with a CTA like “Get the Slide Deck + Bonus Tips—Scan to Join.” Offer real value in exchange for their email.

Real World Example:
At HubSpot’s INBOUND conference, multiple vendors saw email opt-in rates of over 35% using QR codes with free resources and digital swag.

5. Add QR Codes to Business Cards

Why it works: Business cards are great for quick exchanges—but often end up forgotten.

Pro Tip:
Make your QR code link to a mobile-optimized landing page with a warm welcome message and a newsletter opt-in. Include a personal video or thank-you message for bonus points.

Stat to Share:
A study by Adobe found that adding video to your landing page can increase conversions by up to 80%.

6. Put QR Codes on Vehicle Wraps or Outdoor Signs

Why it works: Mobile businesses and service providers can turn every mile driven into a lead-generating opportunity.

Helpful Hint:
Keep the messaging short and clear: “Scan to Join Our Insider Club for Exclusive Discounts!” Use a vanity URL in case someone can’t scan.

Pro Tip:
Include your QR code on yard signs, A-frames, and community boards too. QR codes don’t sleep.

7. Use QR Codes in Presentations or Webinars

Why it works: Viewers are already engaged—give them a quick way to get more value.

Helpful Hint:
Display a QR code during your closing slide to access bonus content, tools, or a resource bundle. Say something like “Want the full toolkit? Scan to get it via email.”

Pro Tip:
Use a countdown timer while the QR code is displayed to drive action before the webinar ends.

8. Feature QR Codes in Restaurant Menus or Cafes

Why it works: Dining guests often have idle time—and phones in hand.

Helpful Hint:
Offer something that feels exclusive: “Join Our VIP Club and Get a Free Dessert on Your Next Visit!” QR codes on table tents, receipts, or menu pages work great.

Bonus Stat:
Restaurants that use QR-based loyalty programs see a 15–25% increase in repeat visits (Source: Toast POS).

9. Add QR Codes to Social Media Graphics or Stories

Why it works: QR codes in digital spaces bridge users directly to your list without needing them to search or click around.

Helpful Hint:
Platforms like Instagram and Pinterest allow you to add QR codes to image posts and stories. Use them to promote gated content, free guides, or giveaways.

Pro Tip:
Use UTMs with your QR code links to track which platform or post drives the most sign-ups.

Wrapping It All Up

QR codes aren’t just for menus or payments—they’re one of the most underrated list-building tools available. They make it effortless for people to go from interest to action, especially when combined with a compelling incentive and a mobile-friendly opt-in form.
