A 60.6% Open Rate — What That Means
The average commercial email marketing open rate across all industries hovers around 21%. The average promotional email open rate is even lower—closer to 15–18%.
Informed Delivery's 60.6% daily open rate isn't a campaign-level metric—it's an everyday behavior. Subscribers open it because it's useful: they want to know what's arriving in the mail that day. That context puts your brand's full-color image in front of an engaged, expecting audience.
For comparison, the Informed Delivery open rate is nearly 3× higher than the industry benchmark for email marketing. This creates a high-value impression channel that your competitors in the digital ad space simply can't replicate.
Who Are Informed Delivery Subscribers?
Understanding the subscriber profile helps you see why this audience is so valuable to direct mail marketers.
Homeowners & High-Value Households
Subscribers tend to skew toward homeowners and higher-income households—demographics that are especially responsive to home services, real estate, financial services, and retail direct mail campaigns.
Active Mail Recipients
People who enroll in Informed Delivery are, by definition, paying attention to their mail. They're more likely to open physical mailpieces, respond to offers, and take action on calls-to-action than the average household.
Rapidly Growing Audience
Enrollment has grown consistently since the program launched. More than 62 million households are enrolled as of 2025, with USPS continuing to expand eligibility and market the service nationally.
Satisfaction & Recommendation Rates
High satisfaction and word-of-mouth recommendation rates signal continued organic growth for the subscriber base—which directly benefits advertisers running Informed Delivery campaigns.
92% of Informed Delivery subscribers report being satisfied or very satisfied with the service, according to the 2025 USPS Year in Review.
Nearly 4 in 5 subscribers say they would recommend Informed Delivery to friends, family, or colleagues—driving continued organic growth.
What it means for advertisers: High satisfaction = habitual use. When subscribers are satisfied and recommending the service, enrollment grows and the channel's reach increases—benefiting every business that runs Informed Delivery campaigns with Catdi Printing.
