Direct Mail Printers & UK Mailing House
Our Yorkshire mailing house combines direct mail printing, data processing, enclosing and Royal Mail Mailmark sortation in-house.
Direct mail remains one of the highest-response marketing channels available - but only when the data is clean, the personalisation is accurate and the postage is optimised. Fretwell handles every part of that process in-house, under one roof in Keighley, West Yorkshire, with ISO-certified quality control at every stage.
As a Royal Mail Approved Mailing House and Mailmark accredited supplier, we qualify your campaigns for the best available postage rates automatically. Mailmark is Royal Mail's digital barcode scheme that enables full campaign tracking, delivery confirmation, and unlocks volume postage discounts unavailable to unsorted mail. Combined with downstream access - postal handover to Royal Mail via a third-party carrier at a lower tariff - we routinely save clients 15-30% on postage costs, without any extra burden on your team.
From 5,000-piece local charity appeals to multi-million-piece financial services campaigns, we have the capacity and the experience to deliver on time and on brief. Our client base includes some of the UK's largest charities, financial institutions and membership organisations - all of whom trust us with their most sensitive audience data. Typical campaign lead times run 5-10 working days from approved artwork and data; we recommend booking your drop date in advance so we can plan capacity around your schedule.

How Mailmark Saves You Money
Mailmark is Royal Mail's digital barcode scheme for volume mailers. When we sort and barcode your mailing to Mailmark standard, your campaign qualifies for Advertising Mail pricing - typically 15-30% lower than unsorted first or second class postage on a 20,000-piece mailing sending at £0.35 per piece unsorted, Mailmark sortation alone can save over £1,500 before downstream access discounts are applied.
Downstream access adds a further saving by handing your sorted mail to Royal Mail at a regional delivery office rather than a collection point, cutting the final-mile charge. We manage the entire submission process - sortation, barcoding, manifest preparation and handover - so you receive all the savings without any operational overhead on your side.
How a direct mail campaign works at Fretwell
Data processing & hygiene
We receive your mailing list and run it through PAF (Postcode Address File - the Royal Mail's definitive UK address database) validation, de-duplication and gone-away suppression to ensure maximum deliverability before a single piece is printed.
Print & personalisation
Outer envelopes, inserts and enclosures are printed and personalised in-house. Variable data printing means each pack can carry a unique name, address and personalised message.
Enclosing & assembly
High-speed camera-matched enclosing lines insert the correct items into each envelope and verify pack integrity - 100% accuracy on every personalised pack.
Sortation & postal handover
Packs are sorted and barcoded to qualify for Mailmark (Royal Mail's discounted postage scheme for volume mailers) rates. Downstream access (postal handover to Royal Mail via a third-party carrier at a lower tariff) further reduces postage cost. We manage submission and track every despatch.
