What The Letterbox Consultancy Ltd. does

The Letterbox Consultancy Ltd. is a UK-based, privately held door drop distribution planning and advisory firm headquartered in Cheshunt. The company provides independent, impartial advice on the distribution of unaddressed direct mail and leaflets to residential and business properties, targeting local, regional, and national brand clients. It claims over 50 years of operating experience and positions itself as the UK's only independent and impartial door drop provider, with national coverage delivered through a combination of an authorised Royal Mail Door to Door Reseller relationship and its own UK-based team network supporting both solus and shared distribution models.

The firm's core product is SMART-Drop, a proprietary targeting service that enables door drop distribution planned at the individual postcode unit level (e.g., EN8 9HU), which is GDPR-exempt and designed to minimise wastage and improve ROI. Targeting and audience selection are built on licensed third-party datasets, including Experian MOSAIC, TGI, and JICMAIL audience measurement data, with the company holding JICMAIL Platinum Organisational Accreditation, the highest tier offered by the industry body. The wider service portfolio covers Royal Mail Door to Door, in-house team distribution, free newspaper distribution, and Partially Addressed Mail, giving clients a mix of fully unaddressed, partially addressed, and fully addressable options.

The Letterbox Consultancy generates revenue on a transaction-fee basis tied to distribution volume, geographic targeting scope, and campaign complexity, with quote-based pricing rather than publicly disclosed rates. Its go-to-market is sales-led B2B, supported by a content marketing presence through its website and case study portfolio. Named clients include Deliveroo, Cancer Research UK, Fishpools (a multi-decade relationship dating to the mid-1990s), and Cushelle (SCA Group). The company holds no disclosed institutional investors, parent entity, or subsidiaries.
