Case Study: How Personalised House Anniversary Cards Drove $512K in Listings for a Leading Real Estate Agency

In an industry where relationships drive results, one forward-thinking real estate agency turned to personalized mail to strengthen their local presence and win more listings. The results speak for themselves: $512,000 in commissions generated from a $14,000 investment, delivering a remarkable 3600% ROI.

The Challenge
Like many agencies, this team of three agents recognised that staying top-of-mind with past clients and local property owners was critical. But traditional marketing—emails, social media, even occasional flyers—was becoming less effective in cutting through the noise. They needed a more personal, scalable solution to maintain relationships and uncover listing opportunities.

The Cardly Solution
Enter Cardly. The platform allowed the agency to automate the sending of personalised house anniversary cards—high-quality, handwritten-style cards addressed directly to clients and neighbouring homeowners.

Each card was tailored to the recipient, including:

• The homeowner’s name
  
• A mention of their property and how many years they’ve lived there
  
• A unique QR code linking to a booking page for a free property appraisal
  

This approach created a memorable and tactile touchpoint that stood out from digital noise and generic direct mail.

Over 12 months, the agency sent 3,330 cards across three distinct client lists—one for each agent.

The Results
The campaign exceeded expectations:

• 13.47% of recipients scanned their QR code—a strong engagement rate for direct mail.
  
• 22 homeowners listed their property for sale directly through the campaign’s appraisal booking link.
  
• These listings generated $512,000 AUD in total commissions, against a mailing cost of $14,000 AUD.
  

Why It Worked
Cardly’s automation eliminated manual work, while personalisation created genuine connections. The handwritten look and feel of the cards lent authenticity, and the QR codes made it effortless for recipients to take action.

The Takeaway
For real estate agencies, Cardly proves that a modern, automated approach to direct mail can deliver extraordinary returns. Personalised house anniversary cards are more than just a nice gesture—they’re a proven strategy for building loyalty, winning listings, and growing commissions at scale.
