OK to printNo more nasty surprises
No more nasty surprises with the mechanical processing of your letters: play it safe before every bulk mailing by getting an "OK to print" from our Swiss Post specialists.
Nothing could be more annoying: you’ve planned your bulk mailing campaign in meticulous detail, but you still end up being surprised by additional costs. All because your mailings fail to comply with Swiss Post's design requirements.
Don’t leave anything to chance, send a test letter to the final proof specialists in your area. No-one has a better knowledge of the design guidelines for letters or of the specifications required by fully automated letter-sorting machines in terms of formats, weights and materials.
Enquiries submitted using the online contact form will be answered within 24 hours (working days). If you submit a written enquiry by post, you will receive your "OK to print" within 2 to 3 days of the arrival of the test letter.
