Fretwell Print & Direct Mail

Mailing Insert Printing

Make every item in the envelope or parcel work. We print leaflets, forms, vouchers and inserts designed to be enclosed, then enclose them in-house at our Keighley mailing house.

What we print

Inserts designed for the pack they go into

An insert is any printed piece that travels with something else: a leaflet in a direct mail pack, a Gift Aid form in an appeal, a voucher in an e-commerce parcel or a flyer in a magazine mailing. It has to earn its place, because every extra item adds weight, cost and something for the reader to look at. It also has to fit: the size, fold and stock need to suit the envelope or parcel and the machine that encloses it. Tell us what the insert travels with and how it will be enclosed, and we can help you plan it with the rest of the pack.

Direct mail packs with printed inserts ready for despatch

Direct mail inserts

Leaflets, response forms, reply slips and Gift Aid declarations enclosed with a personalised letter. Plan their folded size, the order they go into the envelope and which one the reader sees first.

E-commerce and parcel inserts

Product inserts, cross-sell leaflets and vouchers enclosed with online orders. A unique barcode or QR code on each voucher lets you measure redemption.

Magazine and newsletter inserts

Flyers, renewal forms and event invitations sent alongside a members' magazine or newsletter. These can be enclosed with the publication or inserted loose into the envelope.

Paper & finishes

Choose the stock for the job the insert does. A form that will be filled in and returned works best on an uncoated paper that takes a pen. A leaflet carrying photography may suit silk or gloss. Lighter stocks keep the overall pack weight down, which can affect the postage price on a large mailing.

FSC-certified stocks are available for inserts, and charities using FSC-certified paper may qualify for Royal Mail's Sustainable Mail discount. Finishes are usually best kept for the outer or a hero leaflet rather than every insert.

Folding, perforating and enclosing

Inserts are folded and trimmed in-house, and perforations can be added for tear-off slips and vouchers. Our folders include scoring and perforating, so forms and reply slips can be produced in the same pass as the fold.

Our three Buhrs enclosing lines each have multiple stations and a friction feeder, plus 4-way Taurus camera matching and a Driver Southall checkweigher. Camera matching checks that personalised inserts end up in the right pack, which matters when a form carries a supporter's reference or a voucher carries a unique code.

Litho or digital printing?

Inserts that are the same in every pack can be printed by litho for longer runs, or digitally for shorter runs and versions. Personalised inserts, such as pre-filled forms, numbered vouchers or tailored offers, are printed digitally or with inkjet personalisation from your data.

Because inserts are printed and enclosed at the same site, we can plan them as a set: their sizes, folds and personalisation are checked against the envelope and the enclosing line before printing starts.

Mailing & trade print

We process the data, print and enclose the pack, then prepare qualifying UK mailings for Royal Mail Mailmark sortation in-house. Irish mailings are sent through An Post. Keeping the work under one roof avoids moving printed inserts between a printer and a separate mailing house.

For e-commerce and retail clients, inserts can be supplied to your fulfilment team; tell us how they need them packed. Agencies and resellers can commission inserts and enclosing as unbranded trade print under NDA.
