Frequently Asked Questions

What are blue envelopes used for?
Blue envelopes suit corporate correspondence, institutional communications, charity direct mail, educational mailings, and personal occasions including baby shower invitations, baptism and christening cards. Pale blue reads as calm and approachable; mid-blue as professional and reliable; navy as authoritative and premium.

What shade of blue should I choose for a direct mail campaign?
Pale and mid-blue tones allow direct address printing and franking, and work well across both consumer and corporate mail. Very dark navy envelopes may require a white address label for Royal Mail legibility compliance. Test address printing on a small batch before committing to the full mailing.

The range covers over 40 sizes including standard formats: C7 (82 x 113mm), C6 (114 x 162mm), DL (110 x 220mm), C5 (162 x 229mm), C4 (229 x 324mm) and a range of square formats. Check individual product pages for the full size listing in blue.
