We’ve seen it time and time again: a campaign that works in one market often stalls in the next. The data is thinner, and the address format differs. The suppression rules change, and nobody knows when the packs actually landed.
That is the problem with international direct mail. Domestic capability does not scale. It has to be rebuilt market by market.
This guide covers five providers: IMG (Intermedia Global Ltd), The Mailing People, Redc Marketing, Baker Goodchild and Romax. 
What Makes International Direct Mail Different From Domestic Direct Mail?
With every market, the requirements for the data, the addresses, the rules, and the postal system change. You are running several campaigns, not one large one.
Six requirements follow:
- Data: coverage varies by market, so international direct mail data needs local checks
- Addresses: formats and naming conventions differ by country.
- Suppression: local suppression and preference files apply in each market.
- Privacy: rules apply market by market, not as one global rule.
- Postal systems: delivery windows differ, and the network keeps fragmenting.
- Localisation: it goes past translation into salutations, currencies, formality and local naming.
The Universal Postal Union reports that the 30 to 50 high-frequency postal corridors of 2019 had splintered into over 150 pathways by 2025. And that shift has introduced further complexity for international DM at the postage and fulfilment stage. Make sure you check against the six requirements when selecting your direct mail agency. No single agency meets all six. Each meets a different subset, and we label every entry accordingly.
The Top 5 International B2B Direct Mail Agencies
We have grouped the top five B2B direct mail agencies by reach:
- Full multi-market delivery: IMG (Intermedia Global Ltd)
- International mailing from a UK base: IMG (Intermedia Global Ltd), The Mailing People and Baker Goodchild.
- International postage listed, with little detail: Romax.
- UK-focused planning and creative: Redc Marketing.
Reach matters because gaps surface after the mail leaves the building. Duplicates reach one contact twice, and opted-out records get mailed. Packs land weeks apart and nobody can tell.
Each entry covers b2b direct mail campaign design and delivery to a different depth. Treat the labels as a filter, so you never assume reach a provider has not shown. That keeps your global direct mail campaigns grounded in evidence.
1. IMG (Intermedia Global Ltd)
Intermedia Global Ltd (IMG) is a London-based B2B marketing consultancy. It was ranked 109th in the FT1000 2026, which lists the European companies with the highest revenue growth between 2021 and 2024. It also sits in the top 10 UK agencies in the B2B Marketing UK Agencies Benchmarking Report 2026.
IMG (Intermedia Global Ltd) traces its origins to 2003 and serves clients globally from offices in London and Bedford. It works with marketing teams at organisations such as HSBC and Shell.
It works across four areas: marketing operations, data, marketing technology and campaigns. That structure suits multi-market direct mail, because one team handles every stage.
IMG’s (Intermedia Global Ltd) data practice follows four steps: audit CRM records, append missing information from trusted sources, verify each update for accuracy and GDPR compliance, then return records ready for your systems.
- Data: it blends global providers with specialist local datasets, because coverage and address accuracy differ by market.
- Cleansing and suppression: direct mail data cleansing and suppression covers address verification, de-duplication, customer suppression, opt-out suppression and previous-campaign suppression.
- Compliance: local privacy rules and suppression requirements are planned country by country, with market-specific screening built in.
- Localisation: direct mail localisation covers naming conventions, salutations, address formats, currencies and formality, alongside translation.
- Personalisation: variable data printing is driven by market and sector.
- Deployment: print, fulfilment, international logistics and market-by-market scheduling, with international postal optimisation planned around when packs should land.
- Measurement: each market gets a confirmed landing date. Keycodes, QR codes, PURLs, holdout groups and matchback then show response by market.
- Modular model: use IMG only for the markets you cannot run internally.
CEO Steve Kemish sums up the approach: “Bad data doesn’t announce itself – it just quietly makes every campaign a bit less effective than it should be.”
Best for: programmes running across several countries through one accountable team.
Not for: a single-market campaign.
If you want a B2B direct mail marketing company that can plan and deliver each market, IMG (Intermedia Global Ltd) fits that brief.
2. The Mailing People
The Mailing People is a family business in Farlington, Portsmouth. It covers print, personalisation, postage, data cleansing and fulfilment, with an in-house design agency and ISO 27001 certification.
Its site mentions “UK and international mailing projects” but does not describe sourcing for international direct mail data. Data cleansing is offered, so ask how it handles records outside the UK.
Its print services include lithographic, digital and inkjet printing. The company also handles personalised letters and high-volume variable data campaigns. These services cover several stages of B2B direct mail campaign design and delivery.
Postage solutions draw on multiple postal and distribution channels. The company also provides secure direct mail data management and cleansing. For multi-market direct mail, buyers should confirm international address validation, direct mail preference screening and country-specific suppression processes.
- Suited to: UK teams that want production and postage in one place.
- Not suited to: country-by-country compliance planning.
3. Redc Marketing
Redc Marketing is a full-service direct mail agency in Manchester. It plans campaigns with its own Fall Out Model and works through established UK printers.
B2B is a specialist area, covering lead generation and dimensional mail. Its Fall Out Model tracks where readership and response fall away. Its site shows no delivery for global direct mail campaigns.
Its services span campaign strategy, audience data, copywriting, creative development, print production and reporting. B2B projects include lead generation, account-based marketing and high-value mail formats. This makes its offering relevant to businesses planning targeted domestic campaigns.
Redc also provides campaign performance analysis, including response tracking, audience insights and comparisons between test and control groups. These services can inform future campaign design and delivery. However, businesses considering international direct mail should confirm whether the agency can coordinate overseas production, international postal optimisation and direct mail delivery tracking across multiple markets.
- Suited to: campaign planning and supplier coordination.
- Not suited to: running markets you cannot reach yourself.
4. Baker Goodchild
Baker Goodchild is a Birmingham provider that claims 30+ years of experience. It runs B2B and B2C campaigns and offers data cleansing, creative, print, postage and returns.
It lists international tracked and signed mail and courier services. Named partners include Asendia, Jersey Post Global Logistics, Mail Africa and Mail Americas. Its in-house systems link to CRM and ERP platforms.
Its international mailing service covers letters, large letters, packets and mailbags. The company works with postal partners to select routes and services based on delivery requirements. Its offering includes international direct mail and access to postal networks serving more than 200 countries and territories.
Baker Goodchild also provides data cleansing, deduplication, validation and segmentation. Its carrier network and routing technology support international postal optimisation. Businesses planning global direct mail campaigns should still verify the available international direct mail data, direct mail localisation and country-specific compliance checks before commissioning a campaign.
- Suited to: international postage options through named partners.
- Not suited to: deep localisation, which its site does not describe.
5. Romax
Romax is a South London direct mail company based in Orpington. It handles design, print, fulfilment, data management and transactional mail for B2B and B2C clients, and its managing director has over 25 years there.
Its site lists “Postage in the UK and international” with no further detail.
Romax also offers personalised B2B and B2C mailings, machine and hand enclosing, and mail fulfilment. Its data acquisition service provides access to mailing lists, while its data management services address data accuracy. These capabilities cover several operational stages of direct mail campaign preparation.
The company also provides membership management and multi-channel marketing across print, email and text. For businesses considering international direct mail, the key questions concern overseas data sourcing, international address validation and direct mail preference screening.
Buyers should also confirm whether delivery tracking and market-specific suppression are available for each destination.
- Suited to: London-area B2B teams that need design and print.
- Not suited to: multi-market programmes.

Running B2B Direct Mail Across Multiple Markets
Strong international campaigns need consistent targeting, relevant local messaging and reliable delivery. They also require accurate data, appropriate suppression checks and measurable results in every market.
Before launching, check the quality of your international direct mail data, confirm local compliance requirements and agree delivery timelines. Ask providers how they handle direct mail localisation, international postal optimisation and delivery tracking. These checks help prevent avoidable errors and make campaign performance easier to assess.
International direct mail is not simply a larger domestic campaign. Each market brings its own data, language, postal and regulatory requirements. Treat every destination as a distinct campaign, while keeping the wider programme aligned.
