About Postmarkr
Sending a letter shouldn’t require owning a printer or making a trip to the post office.
Postmarkr helps small businesses send invoices, customer updates, and everyday business letters. You review your document and approve the total before paying. Our commercial print partner handles printing and mailing preparation, and USPS delivers your letter.
Printed by a nationwide commercial print network.
Commercial printing, even for one letter. Your letter is produced through our commercial print partner's network of vetted U.S. printing facilities. The network handles printing and mailing preparation, from your approved document to an envelope ready for USPS.

Your mailing, step by step.
Review every page before you pay.
We check the recipient and return addresses against USPS records and add a separate address page for the envelope windows. You review every page and the total before paying.
Prepared for USPS.
Your letter is printed, enclosed, sealed, and supplied with First-Class postage before entering the USPS mailstream.
Follow your letter in your account.
Your Postmarkr account shows processing updates and USPS scans when available.
Postal scans can be delayed or missing; they are not proof of delivery.
What your recipient receives.
Printed on proper letter stock
Your document is printed on 8½ × 11-inch, 60 lb text-weight paper, in black and white or color, with single- or double-sided printing according to your selections.
Folded, enclosed, and sealed
Mailings of up to six sheets, including the address page, are folded into thirds and placed in a standard #10 double-window envelope. Longer documents travel in a larger flat envelope. The envelopes have an interior security tint to help keep their contents private.
Protection for your document, through printing.
Documents are encrypted in transit and at rest. Our commercial print partner undergoes annual independent SOC 2 Type 2 audits and regularly audits its printing partners against security, privacy, and operational standards.

The Postmarkr Editorial Team researches and reviews practical guidance on direct mail, USPS services, and business mailing. Articles draw on primary sources and are updated when rates or requirements change.
Our guides use primary sources, including current USPS materials. We check postal facts against our maintained fact and claims libraries. AI tools may assist with research or drafting; a human editor checks the sources and final copy. Each byline identifies the person or team responsible.
