Digitally Addressed or Hand Addressed Direct Mail: Which has the highest open and response rate?

TEST DETAILS:  To determine the “true” open and read rates, we conducted a case study with 4,000 participants divided into 8 test groups of 500. Each recipient was mailed a FREE $25 check as part of the study. The number of checks cashed in each group served as a direct measure of how many recipients opened and read the mail.

Below are the actual results, showing the number of recipients who opened the envelope and cashed the check.

The Effects of a Handwritten Letter or Card in Direct Response Mailing

A high-end pool and landscape company, has long relied on direct mail to attract new customers. Their standard marketing package included a brochure and a typed letter, sent in a digitally addressed 6×9 envelope—a strategy that consistently delivered strong results for years.

To explore ways to enhance their response rates, we conducted a test. We swapped the standard envelope for a hand-addressed one with a live stamp, and replaced the typed letter with a handwritten card. The goal? To see how these personalized touches could impact engagement and drive even greater success.

The results were eye-opening!
