Direct mail delivers an average ROI (Return on Investment) of £42 for every £1 spent, making it the highest of any paid marketing channel. Yet many businesses still overlook it in favour of digital channels that are increasingly crowded, expensive, and easy to ignore. That's a missed opportunity.
Whether you're new to direct mail or looking for a reason to add it back into your marketing mix, this guide covers the ten most compelling reasons why it works so well.
The main benefits of direct mail are its high open and response rates, the trust consumers place in physical mail, its versatility as a format, and its ability to complement and amplify digital marketing campaigns. Below, we break each one down in detail.
Direct mail is one of the most personalised marketing channels available. Every element of a mail piece can be tailored to the individual recipient, such as their name, purchase history, location, preferences, a personalised offer, or even a bespoke image or QR code linking to a unique landing page.
This matters because personalisation works. According to Keypoint Intelligence, 97% of direct mail users report higher response rates with personalised mail, and 56% say the improvement is significant. Adding just a recipient's name increases response rates by 135% (Source: WhatTheyThink).
With Stannp.com, personalisation is included at no extra cost. Unlike traditional print shops that charge more for variable data, the platform prices personalised and identical mail pieces the same, making it easy to personalise every single piece without blowing your budget.
The best direct mail campaigns reach the right people, not just the most people. Direct mail gives you precise control over who receives your message, allowing you to segment by demographics, geography, purchase behaviour, spend value, contact frequency preference, or psychographic factors like interests and lifestyle.
For UK businesses, Stannp.com's ProspectFeed feature takes targeting further still. It draws on Companies House data to identify newly registered businesses in your chosen sector and location. So you get a fresh, highly relevant prospecting list updated daily.
Smarter targeting means less waste, better response rates, and lower cost per acquisition.
One of the practical advantages of direct mail is its flexibility. The format you choose from postcard, letter, self-mailer/greetings cards, or something more bespoke can be matched precisely to your campaign objective, audience, and budget.
Postcards work well for promotions, reminders, and event invitations. Letters are better suited to formal communication, statements, or longer copy. Self-mailers sit in the middle, as a folded format that delivers marketing messages without the cost of an envelope.
Digital advertising has a trust problem. 87% of people consider mail to be believable, compared to 48% for email (Source: Postcardmania). Physical mail, by contrast, benefits from a level of familiarity and credibility built up over centuries.
For brands trying to build credibility with new audiences or re-engage lapsed customers, this trust advantage is significant.
Direct mail open rates are typically higher than emails. But it's not just about opening. People spend time with physical mail. According to the 2024 Vericast Direct Mail Influence Study, consumers spend 45% more time engaging with direct mail than with digital content, which equates to 1.6 minutes vs 1.1 minutes. (Source: The Financial Brand).
There's a scientific reason why direct mail performs so well, and it goes beyond open rates. Research conducted by Ipsos and Neurons Inc. for Canada Post found that direct mail requires 21% less cognitive effort to process than digital content, meaning your message is easier to understand and more likely to land. Recall was 70% higher with physical mail than digital, and motivation to take action was 20% higher.
Separately, University of Valencia research found that comprehension is 6–8 times better with physical reading material than digital. (Source: University of Valencia). In a world of digital overload, the physical format of direct mail gives it a natural attention advantage.
Direct mail doesn't have to work in isolation, and actually, it performs best when it doesn't. According to MarketReach, including direct mail in digital and TV campaigns increases overall campaign ROI by 12%. When paired specifically with email, response rates jump to 27%.
Stannp.com makes integration straightforward. The platform connects with tools like HubSpot, Salesforce, Zapier, and Make, so you can trigger direct mail sends based on customer behaviour and coordinate physical and digital touchpoints as part of a single customer journey.
A common misconception about direct mail is that it's hard to measure. It isn't. Modern campaigns can be tracked using QR codes linked to unique landing pages, personalised URLs (PURLs), campaign-specific discount codes, dedicated phone numbers, or direct sales attribution.
With Stannp.com, QR code tracking is available. You can see exactly how many recipients scanned, when, and what action they took, giving you clear, attributable data for every campaign.
The results speak for themselves. The average direct mail response rate is 4.4%, compared to email's 0.12%, making direct mail approximately 37 times more effective at generating responses (Source: Mail Processing Associates).
Creating a direct mail campaign doesn't require a print background, a design agency, or weeks of lead time. Stannp.com's platform lets you upload your own design or use the in-platform editor, upload your recipient list as a CSV, preview your mail piece, and approve all in a matter of minutes.
For businesses without an in-house design resource, templates are available to get started quickly. And because address verification is built in (using Royal Mail data for UK campaigns), you can be confident your mail is going to valid, deliverable addresses, reducing waste before it happens.
Cost-per-send comparisons often favour email. But cost-per-response is a more useful metric, and when measured that way, direct mail is highly competitive.
With an average response rate of 4.4% versus email's 0.12%, you're getting significantly more responses for each campaign. (Source: Mail Processing Associates).
