Mail your flat and lightweight products in SendProof® fit-through-the-letterbox boxes with your own printing.

Professional packaging

Letterbox boxes printed with your own company logo, slogan or image stand out. They give your mailings a professional look and enable the recipient to see immediately that the package is from you. Do you have your own shop or webshop and would you like to be able to buy mailing boxes with your own printing in small quantities? Order as few as 100 pieces from us and we will print your SendProof letterbox boxes in full colour. And, thanks to the short delivery time, just five working days after you approve the print proof you will have your inexpensive printed letterbox boxes in house.

Save on mailing costs

A letterbox box is the ideal packaging for flat and lightweight products that are too large for an envelope, but small enough to fit through a letterbox. The boxes are 2.8 cm high so fit through every standard letterbox. This makes them perfect for webshops because as the postman doesn’t need to ring the doorbell your mailing costs are considerably lower.

Closed without tape

The printed letterbox boxes are supplied flat and are very easy to fold into shape. Insert the book, CD, article of clothing or other small product in the box, close the box with the handy self-adhesive strip and your mailing is ready to go. And when it’s been posted through your customer’s letterbox the perforated tear-off strip makes it very quick and easy to open.

Two sizes

Our white SendProof letterbox boxes are made of sturdy cardboard that provides good protection to the contents. They are available in two sizes: A4 and A5. Your own printing will be on the top of the box in an area that is 200 mm wide by 131 mm high for the A5 boxes and 200 mm wide by 211 mm high for the A4 boxes. As the boxes are printed digitally the number of colours is unlimited. This means you can also have photographs printed on your letterbox boxes.

This is how it works

  1. Order your letterbox boxes here.
  2. Upload your logo, text and/or image (read the instructions first).
  3. We send a preview of your design to you for approval.
  4. Within five working days after approval you will receive your printed letterbox boxes.

Your own design

After uploading your file(s), for preference as a pdf, JPG, EPS or AI, we will make a print proof. Within 24 hours we will e-mail you a preview of the print proof that you can approve via e-mail. As soon as we have a definite ‘go ahead’ from you we will start production. Under the tab Downloads on this page you will find templates of the area that can be printed with your design.

Brand SendProof®

SendProof Packaging is our quality label for a complete and well-considered offering of mailing packaging. Good packaging means more efficiency in the chain, less damage, fewer returns and, therefore, lower costs. That is what SendProof Packaging stands for.

Safe and efficient
SendProof’s products are suitable for mailing both food and non-food products safely and efficiently. We offer the right mailing packaging for every product; from books, cosmetics and bottles of wine to fresh vegetables, meat and fish. Maximum product protection, optimum user convenience, cost efficiency, experience and low environmental-impact are key criteria for the SendProof range.

Achieve savings with professional products
In addition to a complete range of standard mailing packaging we also, under the name SendProof PRO, offer advice and inspiration in respect of the complete (e-)fulfilment process. On the basis of the packaging scan, ‘Catch The Savings’, we help you with, for example, the optimisation of your packaging logistics process, the design of creative made-to-measure packaging and/or the development of a sustainable alternative packaging.

With the environment in mind
If you sell a lot online you need a lot of packaging material. With SendProof PRO we pay considerable attention to reducing the volume of ‘empty air’ that is mailed. We also, with the support of our research centre - The LCA Centre - look very carefully at the composition of packaging materials to ensure the environmental-impact of our mailing packaging is as low as possible.

SendProof Packaging is the proof that good mailing packaging pays dividends.
