When you mail a letter online with LetterAgent, you never touch a printer. After you approve the quoted price and pay, the letter goes to a mail facility as a print file, is printed, folded into a double-window envelope, and dropped into the postal network: the post office carries it the rest of the way.
Everything up to payment is your side of the process: describing the letter, checking the draft, approving the exact quoted price. Once payment clears, the letter moves through a production line built for exactly this job. Here is the sequence, end to end:
| Stage | What happens |
|---|---|
| 1. Print job submitted | Your approved letter is sent to a print-and-mail facility as a digital file, with the recipient and sender addresses attached. The verified page count from your quote is what gets printed: nothing more, nothing less. |
| 2. Printed | The letter is printed on 8.5×11 inch paper, single-sided, in black-and-white or colour, exactly as quoted. |
| 3. Folded and inserted | A folding machine folds the pages and slips them into a standard double-window business envelope, aligned so the recipient address shows through one window and the sender address through the other. |
| 4. Postage applied | First-class postage, or the fastest available non-express service: is applied to the envelope. |
| 5. Inducted into the mailstream | The finished envelope joins thousands of others and is delivered to a postal sorting plant, where it enters the normal mail flow. |
| 6. Postal processing and delivery | USPS or Canada Post sorts, transports, and delivers the letter like any other piece of first-class mail. |
A double-window envelope has one window for the recipient's address and a second for the sender's address, and that sender window doubles as the return address, so undeliverable mail has somewhere to go back to. No label printing, no handwriting, nothing stuck on the outside.
The fold has to be precise. Folding machines position the address block within a few millimetres so it lands exactly behind each window. If the fold drifts, the address is half-hidden or unreadable and the piece has to be pulled aside and hand-fixed, so alignment is checked during insertion. This is one of the quiet quality steps in online mailing: a letter that looks fine on screen still has to survive the physical fold.
Many online mailers also print a machine-readable barcode beneath the address: USPS calls its version the Intelligent Mail barcode, so sorting equipment can identify and route each piece without a person reading it. Your letter rides the same automated sorting lines as everything else in the plant.
Once it is in the mailstream, there is no difference. The post office does not know or care that your letter was printed by a service; it gets sorted and delivered alongside letters mailed from blue boxes and post office counters. The difference is only in the front door: instead of you driving one envelope to a mailbox, a facility injects it in bulk into the mailstream at a sorting plant, where it merges with every other letter headed in that direction. Your letter gets no special lane and no shortcut: just a ride that started closer to the plant.
There is no international leg. A letter to a US address is printed and mailed inside the US postal system; a letter to a Canadian address goes through Canada's. Recipients must have US or Canadian addresses, but you (the sender) can be anywhere in the world. Because each letter stays domestic, there are no customs forms and no cross-border delays on the postal side.
