Direct mail research can help you plan a campaign, but figures from different years, audiences and formats are easy to misread. Start with the source and its definition of a response before using a number in your budget.
At Scribble, we write cards with real pens and mail them for you. Your choice of audience, message and timing still matters. Test a small mailing before committing to a larger one.
This guide brings together published figures and practical planning notes. Some source reports require a login. Check the year, sample and method behind any figure you use; a result from another business is not a forecast for yours.
Direct Mail Response Rate Statistics
A response rate needs a denominator and a defined action. If 12 people reply to a 400-person mailing, the observed reply rate is 3%. That is an illustrative calculation, not a Scribble benchmark. If three of those people buy, the observed purchase rate is 0.75%; calling both numbers a “response” would hide an important difference.
Keep customer lists separate from prospect lists. Record who was eligible, how duplicates and bad addresses were handled, and when counting stopped. If you use successfully delivered pieces as the denominator, explain how delivery was established; a mailed status alone does not establish it.
The ANA’s 2023 Response Rate Report was published in February 2024 and requires a login to read in full. We have not verified its full numerical tables here. A report title or a supplier quoting it is not enough to establish a current universal response rate.
Before borrowing a benchmark, look for the report year, country, sample size, audience, format and outcome definition. A self-reported purchase after receiving mail is different from an observed purchase caused by a randomized mailing.

Direct Mail ROI Statistics
Revenue divided by mailing spend is a revenue multiple. For profit-based campaign ROI, first estimate the contribution from additional sales after the costs of fulfilling those sales. Then subtract the campaign cost and divide by the campaign cost. Include list work, creative work, postage and follow-up time.
For example, a campaign costing $1,000 that causes $5,000 in additional revenue at a 40% contribution margin produces $2,000 in contribution. Its illustrative ROI is ($2,000 − $1,000) / $1,000 = 100%. The revenue/spend multiple is 5. These figures describe different things.
Supplier case studies can show how a campaign was run. They usually do not establish a typical return. Check whether quoted revenue includes customers who would have purchased anyway and whether the stated costs include subscriptions and staff time. Leave a result unverified when the method is missing.

Handwritten Mail Statistics
A 2022 field experiment by Kim, Choi and Kim in the Journal of Interactive Marketing examined handwritten notes in online retail. The published abstract reports a spending benefit among loyal customers in that setting, but not among nonloyal customers, and says an incentive reduced the effect. That finding does not establish a universal B2B lift or a Scribble performance claim.
The accessible abstract does not verify the precise “100.5%” spending claim or the claim that photocopies work equally well that appeared in an earlier version of this guide. Those figures and conclusions are not used here. Ask for the full study and inspect the intervention before applying it to another kind of mailing.
Scribble writes messages with real pens, but cannot tell you whether an envelope was opened. Compare replies, appointments or incremental purchases. A handwritten address, a card inside a package and a separately mailed business note are different interventions.
For a practical test, choose a specific occasion and randomly assign eligible recipients to the card or your usual follow-up when feasible. Keep other treatment comparable, allow for postal timing and choose the observation window in advance. Small tests can give uncertain results.

Direct Mail vs Digital Marketing Statistics
Compare channels on the same business outcome. An email open, a QR visit and a purchase are different events. Email privacy features and automated loading can affect open counts; physical mail generally offers no directly observed envelope-open count.
If you add mail to an existing email program, keep the usual emails consistent for both groups. Then compare qualified replies or purchase contribution over the same period. This answers what the added mailing contributed, instead of assigning every later purchase to every touchpoint.
Include the costs needed to repeat the campaign. A physical mailing has production and postal costs; email may have software, creative and preparation costs. Use current quotes at the same audience size. A cheaper contact does not automatically mean a lower cost per incremental sale.

The Neuroscience of Direct Mail
In a June 2015 USPS Office of Inspector General study with Temple University, participants processed digital advertisements faster, while physical advertisements drew more time and stronger emotional and memory responses. Those are findings about the study’s advertising tasks, not a measurement of mailed-card opens or B2B purchases.
The distinction matters when reading neuroscience summaries. Activity associated with value or desire is not an observed completed sale. Use the research to form a question about format, then test the relevant business outcome with your own audience.
The Canada Post/True Impact article linked below is another source to inspect for physical-versus-digital research. This guide does not repeat its numerical lift claims without the full sample, comparison and metric definition.

Direct Mail Demographics and Audience Statistics
An age group is not a mailing strategy. A returning customer who asked for a follow-up differs from a stranger of the same age. Use a relevant relationship or need to define eligibility before considering demographic differences.
Consumer surveys describe what respondents say they remember, prefer or intend to do. They do not show that the same share of your mailing list will buy. Check whether a result applies to all respondents or a smaller subgroup, and whether the sample was weighted.
If age differences matter to the campaign, decide how you will compare them before sending and report group sizes. Avoid drawing a broad conclusion from a handful of purchases in one group. Never infer a sensitive personal event merely because someone fits a demographic profile.

Direct Mail Trends and Volume Statistics
USPS reports 108.7 billion total mailpieces in fiscal year 2025. This is mail volume across USPS categories, not the number of handwritten marketing cards or evidence of campaign effectiveness.
USPS’s fiscal 2025 results report that Marketing Mail revenue increased by $350 million, or 2.3%, while volume declined by 764 million pieces, or 1.3%. The financial release discusses price changes. These figures do not prove that marketers improved targeting or earned a higher return.
Use volume and spending reports to understand the size of a market. A company’s planned budget increase is an intention reported at a particular date; it is not realized spending or proof that a larger budget will work for you. Compare fiscal years with fiscal years and do not label a prior-year survey as current campaign performance.

Direct Mail Personalization and Automation Statistics
A correct name is a basic requirement. Useful personalization explains why you are writing: a completed project, an introduction or a milestone the recipient shared. This guide does not promise a percentage lift from inserting a name.
Automation can reduce repeated setup work, but it also repeats mistakes. Review the longest merged messages, missing fields, recipient exclusions and duplicate events before enabling a rule. Decide who will review skipped recipients and errors.
Scribble supports documented API and inbound-hook workflows. Named native connectors have their own availability; the HubSpot integration is a pilot. Check the current setup guide for the event you want to use. A trigger is not evidence that every eligible card was successfully mailed.
A campaign link or QR code can provide an attribution signal if you implement it. It misses people who respond another way and can be shared. Keep link activity separate from purchases and from any estimate of incremental impact.

Direct Mail Consumer Sentiment Statistics
A survey asking whether mail feels personal answers a different question from whether the recipient will renew a contract. Report the exact question, study date and respondent population when quoting sentiment research.
Customer comments can help improve a message or identify an unwanted mailing. Do not turn a favorable comment into an attributed testimonial without permission, or present a hypothetical example as a customer result. This guide contains no verified Scribble response-rate or client-revenue dataset.
The supplier reports below are retained as further reading. Their commercial interest and differences in research design should remain visible. An accessible link alone does not establish that every figure in a report has been independently checked.

Before you plan a mailing
Use the research to frame a small test, then make the budget decision from your own results:
Define a response. Replies, clicks, appointments and purchases are different outcomes. Compare like with like.
Work out the cost per incremental sale. Include production, postage and follow-up time, and use the margin on each sale to calculate your return.
Choose recipients for relevance. Age alone is not enough to predict who will value your note.
Test the format. Compare a handwritten card with your usual approach before committing to a larger mailing.
Keep industry trends separate from your forecast. Another company’s budget increase does not establish that spending more will work for you.
For a practical starting point, read our guide to handwritten sales notes. Choose one audience and one reason to write.

Frequently Asked Questions About Direct Mail Statistics
What is the average response rate for direct mail?
There is no single response rate that predicts every mailing. Results depend on the audience, offer, format and what counts as a response. Use a benchmark only when its method and audience are relevant to your campaign.
Is direct mail still effective in 2026?
Direct mail can be useful when a physical message suits the relationship and the cost is justified. Test a small mailing, record replies and sales, and compare the result with your usual approach before expanding it.
How does direct mail ROI compare to email?
Compare the incremental profit from each channel after its full costs. A cheap email send is not automatically profitable, and a higher response rate does not automatically make direct mail the better investment.
What age group responds best to direct mail?
Do not choose a mailing audience on age alone. Consider their relationship with your business and whether the message is relevant. Compare results within your own audience before making a demographic claim.
What is the open rate for handwritten mail?
Scribble cannot measure whether a recipient opens a physical envelope. We do not promise a universal open rate. Count replies, appointments or purchases instead, and use those results to decide whether the mailing worked.
