Yes—but selectively. Offline marketing remains useful when a physical format fits the audience and objective, but the evidence does not show it is universally more effective than digital. Direct mail can prompt attention and reported action; out-of-home (OOH) and live experiences can create local visibility and in-person engagement. The practical question is whether a campaign produces incremental results after its full costs are counted.
What the latest evidence says about offline marketing
Recent findings support continued use of offline channels, but they measure different things: consumer survey responses, reported marketer plans, a UK channel benchmark, and one multichannel public-sector pilot. They are not a head-to-head test proving offline beats digital.
- Direct mail: In Lob’s 2026 U.S. online survey of 2,000 adults, fielded in July 2026, 87% said they read mail the day it arrived, 66% liked referring back to it while considering a purchase, and 65% said direct mail had led them to purchase, sign up, or become a customer. These are respondents’ reports, not measured causal lift. Lob also found 34% said direct mail felt more trustworthy than digital communication; that is a reported perception, not proof that all recipients trust mail more. Read Lob’s 2026 Direct Mail Consumer Insights Report.
- OOH and live experiences: In an August 4–5, 2026 U.S. survey by OAAA and The Harris Poll, 73% of adults ages 18–64 preferred products or retailers that engage people through in-person experiences or local outdoor events, and 69% said OOH felt more human than online or mobile ads. Among people who attended a live marketing event, 40% reported making a purchase; that is not a conversion rate for all consumers or evidence the event caused the purchase. See the OAAA survey findings.
- Door drops in the UK: The DMA and JICMAIL’s Door Drop Report 2026 reported £5.40 ROI for door drops in 2025, alongside 1% growth in expenditure and 3% growth in volumes. This is a UK channel benchmark from that report—not a forecast for a specific campaign or another market. Read the DMA Door Drop Report 2026.
- OOH among marketers: OAAA and Winterberry Group reported in March 2026 that 98% of surveyed marketers incorporated OOH into purchase-driven initiatives, and 86% expected OOH investment to increase over the following two years. Those figures describe respondent adoption and expectations, not consumer impact. See the marketer survey.
Which offline channel fits your goal?
Direct mail and door drops put a message into a household or postal area. OOH reaches people in a place—such as a roadside, transit setting, or retail area—while live events offer interaction with attendees. Choose by audience and purpose rather than treating “offline” as one interchangeable channel.
| Channel | Where it reaches people | Most natural uses | Useful response measures |
|---|---|---|---|
| Direct mail | Selected households or postal areas | A tangible offer, a reminder people may revisit, consideration, retention, or a local response | Unique URL or QR code, offer code, dedicated phone number, or a matched-area comparison |
| Door drops | Homes in a chosen delivery area | Local discovery and broad household coverage | Offer code, QR code, unique URL, or comparison with an unexposed area |
| OOH | People passing a specific roadside, transit, retail, or other placement | Place-based visibility, awareness, and local discovery | Campaign-specific response route and, where feasible, a comparison area or baseline |
| Live events | Attendees at an event or activation | In-person interaction, sampling, lead capture, or product experience | Leads, redemptions, or purchases tracked against a clear baseline |
These measures can help connect exposure with a response, but a scan or redemption alone does not establish what would have happened without the campaign. For a stronger estimate of incremental impact, use a holdout or matched-area comparison when feasible.

How to test an offline campaign without mistaking correlation for lift
- Set one primary outcome. Decide whether the campaign is meant to generate awareness, store visits, leads, sign-ups, purchases, or retention. A channel can attract attention without delivering the outcome that matters to your business.
- Define the audience and geography. Specify which households, communities, locations, or event attendees should see the message. Keep the delivery or placement area narrow enough to compare with a similar group if possible.
- Build a response route into the creative. Use a unique URL, QR code, offer code, or phone number. Give the audience a reason to respond and make the next step clear.
- Choose a baseline or comparison before launch. Compare results with a pre-campaign period or a similar area that did not receive the treatment, where practical. Record other promotions or changes that could affect the outcome.
- Count full costs and incremental results. Include production, postage or media placement, staffing, and the cost of an offer. Compare those costs with outcomes above the baseline, not simply every response received during the campaign.
- Decide whether to scale, revise, or stop. If the campaign produces a measurable improvement at an acceptable full cost, test expansion. If results are unclear, improve the comparison or response mechanism before assuming the channel failed—or succeeded.
What the ONS Birmingham pilot can—and cannot—show
The Office for National Statistics describes a 2025 Birmingham communications pilot that combined direct-mail postcards, broadcast video on demand (BVOD), digital OOH billboards, and an ONS landing page. It aimed to address trust barriers and encourage participation in social surveys. The evaluation compared trial-period responses with a pre-trial period and the same period in the previous year, using Manchester as a comparator; its analysis used Transformed Labour Force Survey data from 586 respondents.
The ONS says operational limitations made it difficult to attribute changes to individual interventions or identify affected demographic groups. The pilot illustrates how offline and digital touchpoints can be combined and evaluated, but it does not isolate the effect of postcards or billboards. Read the ONS account of the Birmingham pilot.

Why a published ROI figure is not a campaign forecast
The DMA/JICMAIL door-drop figure is useful context for the UK channel, but the return on a particular campaign depends on its audience, offer, execution, costs, and measurement. The Universal Postal Union’s 2024 Direct Marketing Study cautions that direct-mail ROI is not simple to measure consistently and that effectiveness varies by campaign and sector. See the UPU Direct Marketing Study page.
For personal-finance providers, retailers, and other businesses, the same discipline applies: do not compare a consumer’s stated preference directly with a channel ROI figure. Set a relevant outcome and a fair comparison first, then judge whether the campaign created enough additional value to justify its cost.
