What is QR Codes?

QR codes (Quick Response codes) are two-dimensional barcodes that can be scanned using smartphone cameras to instantly access websites, digital content, or special offers. In direct mail campaigns, QR codes serve as a bridge between physical and digital channels, enabling recipients to visit personalized landing pages, schedule meetings, or redeem offers seamlessly.

Modern QR codes support dynamic updates, analytics tracking, A/B testing, and personalization. Best practices include maintaining a minimum size of 1 inch by 1 inch, providing clear instructions, and linking to mobile-optimized landing pages to maximize conversions.
