Marketing campaigns that include direct mail are 52% more likely to report ROI improvements and 43% more likely to report revenue uplift (Source: Marketreach). And yet, many digital-first teams still overlook it.
For years, marketers have focused on the channels they can measure. The ones they can attribute effectively and A/B test efficiently. The channels that don't require a heavy lift.
Direct mail was moved to the bottom of the pile. It was viewed as slow, expensive, and hard to track.
But that assumption is quickly becoming outdated. As digital channels become noisier and more expensive, consumers are craving a return to offline activity. Google searches for analogue hobbies have surged by 160%, and 79% of millennials say they look forward to receiving brand catalogues in the mail.
This points to a wider shift in consumer behaviour at a time when direct mail has become more advanced than ever. Improvements across the mail ecosystem, driven by sustained investment in postal infrastructure alongside the emergence of SaaS platforms like Stannp.com, have created a strong foundation for a new generation of direct mail. Campaigns can now be launched in days rather than weeks, with the engagement and conversion tracking marketers need to measure performance properly.
With direct mail achieving year-on-year growth of 4.8% in 2025 alone, marketing teams sitting on the fence could be missing out on a compelling opportunity: the chance to interact with prospects on a different level by placing a physical piece of mail directly into their hands.
Historically, direct mail was difficult for marketing teams to operationalise. Unlike digital channels that can be managed from a single dashboard, direct mail campaigns could involve multiple suppliers and manual processes, slowing marketing efforts and leaving little visibility into what happens after delivery.
That has changed significantly. Investment in postal infrastructure, data quality, automation and operational systems has made direct mail a reliable and dependable marketing channel, with key improvements including delivery confirmation, advanced tracking capabilities, and more efficient routing and sorting processes.
With the introduction of modern SaaS platforms, direct mail has become more aligned with its digital counterparts, making it easier to create programmatic mail campaigns that can be built, launched and measured from a single platform. Platforms such as Stannp.com now process millions of mail items each month, with over 200 million items handled since launch in 2014.
Together, these developments have created the foundation for something new: a trackable marketing channel delivered through the letterbox.
Digital marketers who are used to seeing data in near real time, with dashboards full of open rates, CTRs, and ROI statistics, may once have viewed direct mail as a black hole that rarely offered such visibility. It became known as a channel that was difficult to test and improve, and even harder to defend in performance-related conversations with leadership.
In fact, research shows that marketers often hesitate to increase direct mail investment due to attribution challenges and lack of ROI clarity without specialist tracking tools.
SaaS direct mail platforms offer a solution to this problem. They merge the physicality of direct mail with the intelligent tracking of a digital campaign, enabling marketers to track customer engagement via QR codes and personalised URLs, so they can be just as granular in their data assessment as they would be for any other digital channel.
Modern direct mail can now support QR code tracking, personalised URLs, campaign attribution, conversion tracking, engagement analytics, and A/B testing. With these tools at a marketing team's disposal, direct mail is no longer a channel of broad assumptions but one that can be proven to be a sustainable growth opportunity.

There's no denying that marketers are under pressure, with budgets flatlining in 2025 and 59% of CMOs reporting they have insufficient budget to execute their goals (Source: Gartner). The difficulty is that it's become harder to stand out in an increasingly overcrowded digital space. Clicks are expensive, and feeds are full of ads competing for attention. Even the best-targeted campaigns have only a moment to land, with the average attention span now being just 8.25 seconds.
This is where a direct mail campaign can make a real difference. While a single Google Ads click can cost £10 or more, a programmatic mail piece can cost around £0.50. That means marketers can reach 20 households for the cost of a single digital click.
These efficiencies are made possible by improvements in postal infrastructure that have made direct mail significantly more cost-efficient to send at scale, including more accurate address validation, automated sorting, pre-sorting discounts, and delivery confirmation and engagement tracking. With nationwide reach and an established delivery network, modern postal infrastructure provides the scale and consistency that enables direct mail to operate as a reliable marketing channel at volume.
And it is not just lower costs that are bringing marketers back to direct mail. Advances in tracking capabilities are also giving teams access to the granular performance data they need, making direct mail a much more measurable and accountable channel than it was in the past.
Short answer: yes. And the numbers back it up.
According to the ANA Response Rate Report, direct mail delivers a median ROI of 112%, higher than paid search at 93% and online display at 89%. For house list campaigns, that figure rises to 161%. These aren't outliers. They're what happens when a channel with high attention, physical presence, and measurable response rates is used properly.
The cost per piece is only part of the equation. What matters is cost per acquisition, and on that measure, direct mail consistently holds its own against channels that feel cheaper on the surface but convert at a fraction of the rate. A £0.50 mail piece that generates a £50 sale is a better investment than a £10 click that bounces.
Direct mail earns its place in the budget not because it's the cheapest channel, but because it delivers.
The marketers entering the direct mail arena are increasingly digital-native teams that have never used direct mail as a marketing channel. They are discovering it for the first time, without historical assumptions about cost, complexity or lack of measurement.
Around 40% of Stannp.com customers had never sent direct mail before using the platform, proving the channel is being adopted by a new generation of marketers. And the results back them up. According to the 2025 Direct Mail Marketing Benchmark Report, 67% of marketers saw improved direct mail performance over the past 12 months, the highest lift among all direct marketing channels, including email and social media.
See our full breakdown for more on the benefits of direct mail, including why it consistently outperforms digital channels on ROI.
A direct mail strategy needn't start from scratch. In fact, many of the same principles used in email and CRM programmes can be applied. Rather than being reserved for large one-off campaigns, mail can now be triggered by consumer behaviour and lifecycle signals, making it more targeted and personalised.
For marketers who are already adept at using behavioural triggers in email and paid media, this familiarity makes adoption of mail much easier. Using a similar playbook, teams can run the following programmes via direct mail:
This lowers the barrier to entry for many marketers, who may believe they need to take a completely different approach to the channel. In many cases, they can simply adapt an existing playbook to a format that offers different attention dynamics and a more physical presence.

As with any marketing tactic, benchmarking is vital for driving informed decisions and ensuring consistent measurement. Stannp.com has analysed millions of mail pieces across thousands of campaigns and multiple industries to establish engagement benchmarks that give marketers a realistic baseline to test from and aim towards.
Typical engagement rates range from 0.43% to 3.55%, with a median of 1.63%. Top-performing campaigns achieve 5.29% engagement or higher. Performance varies by sector too, with Finance and Legal consistently outperforming sectors such as Software, Health and Property.
For a full breakdown of engagement benchmarks by industry, including what separates average campaigns from exceptional ones, see our detailed analysis: Understanding direct mail engagement rates: what does good look like?
One thing the data makes clear: the gap between average and exceptional performance is not explained by channel alone. It is driven by how well campaigns are tested and optimised. To get statistically meaningful data from a direct mail campaign, a minimum send of 1,000 pieces is recommended. Below that, you are unlikely to see patterns you can confidently act on.
One of mail's most underappreciated advantages is its longevity. Digital marketers are used to seeing email performance peak quickly and then drop off just as fast, with opens and clicks clustering shortly after send. Direct mail behaves differently.
Away from the noise of digital ads and cluttered inboxes, mail enters the home and stays there. It can be picked up, put down, revisited, and noticed more than once by multiple occupants. This longer presence changes the response window and how campaigns should be judged.
Mail typically remains in the home for 7–8 days, and consumers often interact with it multiple times throughout that duration (Source: Whistl). Stannp.com campaign analysis shows that second-class mail generates an average engagement time of 9.43 days, while economy mail generates an average engagement time of 7.32 days, challenging the assumption that faster delivery automatically drives better performance. Creative strength and message relevance often matter more than speed of delivery, which has a practical implication for campaign budgeting.
The practical takeaway: extend your attribution windows beyond seven days, avoid judging performance too early, and align your follow-up digital channels with the expected mail delivery timing.
The gap between average and exceptional performance is rarely explained by channel alone. It is driven by how effectively campaigns are tested and optimised. Direct mail now gives marketers more room to test what works across creative formats, calls to action, offers, audience segments, timing, and sequencing.
In one reactivation campaign, a single change in CTA copy drove a more than 10x increase in engagement, with the top-performing version achieving a 7.34% engagement rate and a 4500% ROI. Read the full story in our Equinox case study.
The outcome of direct mail marketing is not simply a result of including the channel in an integrated campaign, but of taking a test-and-learn approach; the same approach that drives performance across every other channel in your mix. For a practical guide to testing in direct mail, see our blog on A/B testing in direct mail: how to find what actually works.
Direct mail offers marketers a new way to reach their audience, providing a contrast to purely digital interactions. However, like any other channel, direct mail works hardest as part of a broader multichannel strategy with multiple touchpoints.
Mail can be used to re-engage audiences who have stopped responding to email, reinforce digital campaigns with a physical follow-up, drive traffic to digital landing pages, or add weight to significant marketing moments that deserve more than another online impression. Research from WARC shows that ROI is increased in 35% of campaigns that use direct mail as part of an integrated strategy, compared with 23% for the average UK campaign.

A direct mail piece has one job: to earn attention in the few seconds before someone decides whether to engage or discard it. Getting that right comes down to a handful of fundamentals.
It needs to communicate the core benefit immediately, not cleverly, not vaguely, but clearly. If someone reads nothing else, the headline should tell them why this piece matters to them.
Every effective mail piece has a single, unambiguous reason to act. One offer, one call to action, one next step. Trying to communicate multiple things at once dilutes all of them.
Most recipients will scan before they read. Visual hierarchy, bold headlines, supporting imagery, and a clear CTA should guide the eye naturally toward the action you want them to take.
The most effective mail pieces go further than a first name, referencing a past purchase, a location, a lifecycle stage, or a behavioural trigger that makes the piece feel genuinely relevant.
Every mail piece should include a QR code or personalised URL that connects the physical touchpoint to a digital experience and gives you the data to measure what happens next. For a full guide to using QR codes effectively, see our blog on QR codes in direct mail: what works, what doesn't, and how to track everything.
CTA copy is the highest-leverage variable in a direct mail campaign. Before committing to a full send, test at least two versions. The difference between average and exceptional performance often comes down to a handful of words.
The best first step is a simple one. Pick a campaign type you already run digitally, a reactivation sequence, a cart abandonment flow, a welcome journey, and run a direct mail version alongside it. Use the same audience, the same message, and the same measurement approach you'd apply to any other channel.
Send at least 1,000 pieces to get meaningful data. Add a QR code or personalised URL to track engagement. Give it the attribution window it deserves, at least seven days before drawing conclusions. Then optimise from there, exactly as you would with any other performance channel.
Direct mail is earning its place as a measurable, scalable channel built for the way modern marketing teams actually work. The renaissance is already underway, and the marketers who move now will be the ones who shape how it's used next.
