Digital advertising may dominate marketing conversations, but physical mail remains one of the largest advertising channels in the United States. Businesses still send tens of billions of pieces of marketing mail to American homes and businesses every year.
In fiscal year 2025, the United States Postal Service processed 56.8 billion pieces of Marketing Mail. That means Marketing Mail represented more than half of all mail volume handled by USPS during the year.
Direct mail has changed considerably over the past decade, however. Overall volume has declined while marketers have adopted better targeting, personalization, QR codes, informed delivery, and multichannel campaigns that connect physical mail with online experiences.
Below, we break down the latest direct mail statistics for 2026, including annual mail volume, response rates, return on investment, Every Door Direct Mail usage, historical trends, and the continued role of physical mail in modern marketing.
Key Direct Mail Statistics for 2026
Despite decades of growth in email, paid search, social media, and other digital advertising channels, direct mail continues to reach millions of American households every day.
Here are some of the most important direct mail statistics entering 2026:
| Direct Mail Statistic | Latest Data |
|---|---|
| USPS Marketing Mail volume | 56.8 billion pieces |
| Total USPS mail volume | 108.7 billion pieces |
| Marketing Mail share of total USPS volume | Approximately 52% |
| USPS Marketing Mail revenue | $15.7 billion |
| Marketing Mail volume in 2016 | 80.9 billion pieces |
| Marketing Mail volume in 2024 | 57.5 billion pieces |
| Marketing Mail volume in 2025 | 56.8 billion pieces |
| EDDM pieces sent in 2025 | Nearly 3 billion |
| EDDM revenue in 2025 | Approximately $617 million |
| Direct mail ROI to house lists* | 161% |
| Direct mail ROI to prospect lists* | 34% |
*ROI figures are based on ANA Response Rate Report research and should be viewed as campaign benchmarks rather than expected results for every direct mail campaign.
USPS generated approximately $15.7 billion in Marketing Mail revenue during fiscal year 2025, up from $15.4 billion the previous year even as Marketing Mail volume declined.
How Much Direct Mail Is Sent Each Year?
USPS processed approximately 56.8 billion pieces of Marketing Mail during fiscal year 2025.
That works out to an average of approximately 155.5 million pieces per day when annual volume is divided across the entire year. It also equals roughly 6.5 million pieces per hour.
Marketing Mail represented approximately 52% of the 108.7 billion total pieces of mail handled by USPS during fiscal year 2025.
In other words, more than half of USPS mail volume now comes from the category that includes advertising, catalogs, newsletters, promotional materials, and other qualifying commercial mail.
The scale is particularly notable considering how many digital alternatives businesses now have available. Email marketing, social advertising, paid search, text messaging, and other channels have all become commonplace, yet tens of billions of physical marketing pieces continue to enter the U.S. postal network annually.
How Much Has Direct Mail Volume Declined?
Direct mail remains a massive industry, but Americans receive considerably less Marketing Mail than they did a decade ago.
USPS processed 80.9 billion pieces of Marketing Mail in fiscal year 2016. By 2025, annual volume had fallen to 56.8 billion pieces.
That’s a decline of approximately 24.1 billion pieces, or nearly 30%, in less than a decade.
The decline has not occurred evenly. USPS Marketing Mail volume fell from 75.7 billion pieces in 2019 to 64.1 billion in 2020. Volume briefly recovered to 67.1 billion pieces in 2022 before declining again.
More recently, volume decreased from 59.4 billion pieces in 2023 to 57.5 billion in 2024 and 56.8 billion in 2025.
Even after this long-term decline, Marketing Mail remains the largest USPS mail category by number of pieces. For comparison, USPS handled approximately 42 billion pieces of First-Class Mail in fiscal year 2025.
Direct Mail Response Rate Statistics
One reason businesses continue using direct mail is its ability to generate measurable responses outside of crowded digital channels.
The Association of National Advertisers has tracked direct marketing performance for more than two decades through its Response Rate Report, which was reintroduced as the ANA Impact Pulse in 2025. The latest study gathered data from 324 participants and examined direct mail alongside email, paid search, social media, and display advertising.
Direct mail performance can vary considerably depending on the audience, offer, creative, mailing format, industry, and whether the recipient already has a relationship with the sender.
This distinction is important when evaluating direct mail statistics. A campaign sent to existing customers generally should not be compared directly with a cold acquisition campaign sent to prospective customers.
Tracking has also become more sophisticated. Previous ANA research found that 82% of marketers tracking direct mail response used online mechanisms such as QR codes and dedicated URLs. This makes physical mail increasingly measurable alongside digital marketing channels.
Direct Mail ROI Statistics
Direct mail can also produce significant returns when campaigns reach the right audience.
ANA research found that direct mail sent to existing house lists produced an average ROI of 161%. Direct mail sent to prospect lists generated a lower 34% ROI.
The difference demonstrates how valuable audience selection can be in direct mail marketing. Existing customers already recognize the business sending the piece, while prospect campaigns must generate interest from consumers who may have no previous relationship with the brand.
Earlier ANA research also found particularly strong results for certain formats. Letter-sized envelopes sent to prospect lists generated a reported 112% ROI in one study, while postcards sent to house lists produced a 92% ROI.
Every Door Direct Mail Statistics
Every Door Direct Mail, commonly known as EDDM, has become another significant part of the direct mail market.
USPS launched EDDM in 2011 to allow businesses to send Marketing Mail to selected neighborhoods, cities, and ZIP Codes without purchasing individual mailing lists.
Nearly 3 billion EDDM pieces were mailed during fiscal year 2025. Those mailings generated approximately $617 million in USPS revenue.
EDDM is particularly suited to businesses interested in reaching consumers based primarily on geography. Restaurants, home service businesses, real estate professionals, healthcare providers, retailers, and other locally focused companies can select carrier routes and deliver advertisements throughout specific areas.
The nearly 3 billion pieces mailed in a single year demonstrate that geographic direct mail remains widely used even as businesses gain increasingly sophisticated digital targeting options.
How Direct Mail Is Becoming More Digital
Physical mail and digital marketing are increasingly being used together rather than treated as competing channels.
QR codes are one of the clearest examples. A recipient can receive a postcard, catalog, or letter and immediately scan a code to visit a website, redeem an offer, schedule an appointment, or make a purchase.
USPS Informed Delivery has created another connection between physical and digital mail. More than 74.8 million customers have enrolled in Informed Delivery since its introduction in 2017.
The service allows eligible residential customers to digitally preview incoming letter-sized mail and manage incoming packages. For marketers, this creates another opportunity for a physical mailpiece to generate a digital interaction.
Direct mail may therefore look very different from the catalogs and promotional letters that dominated the industry decades ago. The physical mailbox remains the destination, but measurement and customer response are increasingly digital.
Is Direct Mail Still Effective in 2026?
Direct mail volume has clearly declined, but the data does not suggest that the channel is disappearing.
USPS still processed 56.8 billion pieces of Marketing Mail in fiscal year 2025. Businesses also spent enough on those mailings to generate approximately $15.7 billion in USPS Marketing Mail revenue.
What has changed is the role direct mail plays within the broader marketing mix.
Rather than replacing email, paid search, social media, and other digital channels, physical mail can provide businesses with another way to reach customers. The 2025 ANA Impact Pulse found that 75% of surveyed marketers were already using multichannel strategies.
