Envelope Stuffing Services
Don't be just an idea.
You imagine it, we create it.
Envelope stuffing is the process of folding, inserting, and sealing printed material into individual envelopes, ready for posting. At any real scale, it is a job for automated machinery rather than hands.
TR2 Creative provides a high-volume, automated envelope stuffing service as the core of our fulfilment operation, currently filling between 5,000 and 7,000 envelopes per day, with the capacity to exceed 10,000 per day as we expand our equipment.
From our base in Stoke-on-Trent, we support companies across the West Midlands, including Birmingham, and throughout the UK, producing every mailing campaign to the highest standard.
What is envelope stuffing?
Envelope stuffing, also called envelope packing or enclosing, is the process of packing printed materials into individual envelopes and sealing them ready for dispatch. A typical job involves folding a letter, inserting any additional items, such as brochures or leaflets, sealing the envelope, and addressing it to the recipient.
Legitimate commercial envelope stuffing is performed by automated industrial equipment rather than by hand at home; it takes machinery, knowledge, and resources to fill thousands of individual envelopes accurately and at speed.
For more complex packing requests, manual hand fulfilment is sometimes the right approach, and we offer that as an additional service alongside our automated line.
Our envelope stuffing capacity
We currently process between 5,000 and 7,000 envelopes per day, and our capacity will exceed 10,000 per day as we bring additional equipment online.
That throughput is built for recurring mailing programmes and large one-off campaigns alike, the kind of volume that is impractical and costly to manage in-house.
Because the process is automated rather than manual, output remains consistent and efficient whether you are mailing 5,000 items or 50,000, and we can scale as your mailing requirements grow.
What our envelope stuffing service includes
Our automated inserting equipment handles automatic A4 folding, so letters arrive print-ready and are folded to fit without manual preparation. It supports multiple inserts in a single pass, a typical configuration being a letter plus up to two leaflet inserts, and seals each envelope automatically as part of the run.
Automated folder-inserters work far faster than manual labour and significantly reduce the likelihood of human error, such as a missing insert or a mismatched item, so every mailpiece is correctly enclosed and finished to a consistent standard.
Because envelope stuffing sits alongside TR2 Creative’s design and print services, we can also create, print and mail a campaign in one seamless operation rather than splitting the job across separate suppliers.
Personalised mailings and direct mail campaigns
Modern mailings are rarely identical, so our service is built to efficiently target specific names and addresses. We produce personalised mailings tailored to each recipient and handle variable addressing, where different data appears on every item in a single run, as well as window-envelope campaigns, where the address shows through from the enclosed letter.
This makes envelope stuffing a natural fit for direct mail. Direct mail remains one of the most effective marketing strategies, valued for its high open rates and strong return on investment.
A well-produced direct mail campaign builds brand awareness and recognition in ways digital channels often cannot. It is ideal for advertising, canvassing and sharing information at scale, and helps you maximise the response from every mailing. The service connects directly with our wider direct mail fulfilment service.
Royal Mail preparation
Filling the envelopes is only part of the job. We also prepare completed mailings for Royal Mail, sorting and presenting them so they are ready for collection and qualify for the appropriate postal service. Getting this preparation right keeps postage efficient and dispatch seamless, which on a recurring programme makes a real difference to both cost and timing.
Why outsource your envelope stuffing?
Stuffing envelopes in-house ties up staff, space and time, and it rarely scales well when a mailing is large or a deadline is tight. Outsourcing reduces the workload for a scaling business, turning a fixed investment in equipment and labour into a flexible, cost-effective service.
It frees your team and resources for the work that matters most, while we securely manage the mailing and store the materials, ready for each run. The savings are not only in money but also in reliability: a dedicated team and proper machinery deliver consistent results that protect your campaign’s quality every time.
Built for high-volume, recurring mailings
This service is designed for organisations with substantial, ongoing mailing requirements rather than occasional small sends, such as membership communications, statements, fundraising appeals, customer mailings, and regular direct mail.
We take pride in producing every job to the highest standard, drawing on our experience, knowledge and attention to detail, and we strive to understand each client’s requirements so the process runs reliably, campaign after campaign.
Our focus on volume and continuity is what keeps turnaround and pricing dependable for genuine mailing programmes.
