Envelope Security

Mail security is a popular concern these days.  Mailers often wonder if mail carriers or other people can see through the envelopes that LetterStream uses and possibly gain access to secret information.

At this time, LetterStream uses Window envelopes but you can rest assured your information is secure!

All our #10 window envelopes have security tint inside them which prevents accidental and intentional viewing of the contents of the envelope.  A security tint is a printed pattern inside the envelope which visually disrupts the viewing of documents inside.
