How to mail a physical letter with USPS from your computer without buying stamps or envelopes

• USPS letter mailing normally requires an envelope, address, and postage.
• Click-N-Ship is useful for packages and some larger envelopes, but it is not the same as a consumer upload-print-mail letter service.
• A print-and-mail service handles printing, envelope prep, postage, and USPS handoff.
• PostalForm lets you upload a PDF or write a letter online, then mails the physical letter through USPS.
• Certified Mail and Express solve different problems: proof versus speed.

For ordinary letters, USPS explains the traditional process: address the envelope, put the letter inside, add the right postage, and send it through a mailbox, collection box, or Post Office location. USPS also sells stamps online and at Post Office locations, kiosks, and many retailers.

USPS Click-N-Ship is different. It lets you buy and print postage for USPS Ground Advantage, Priority Mail, and Priority Mail Express shipping labels. It is useful when you already have a package or qualifying envelope ready to ship, but it does not replace the whole "print my letter, put it in an envelope, stamp it, and mail it" job for ordinary consumer letters.

1. Write the letter on your computer - Use Google Docs, Word, Pages, or PostalForm's letter editor.
2. Save or upload the document - Export to PDF, or write the letter directly online.
3. Enter the recipient and return address - Use the full mailing address, including unit or suite details.
4. Choose the USPS mailing option - First Class, Express, or Certified Mail when available.
5. Approve and pay online - The service prints, envelopes, adds postage, and hands the letter to USPS.

You still get a real physical letter delivered by USPS. The difference is that you did not prepare the physical mailpiece yourself.

You do not need:

• a home printer
• printer ink
• printer paper
• envelopes
• stamps
• a postage scale
• a post office trip

You do need a final letter, the recipient address, a return address, and a way to pay online.

For ordinary letters, usually no. USPS.com is excellent for buying stamps, looking up rates, and creating some online shipping labels, but the normal letter instructions still center on a physical envelope and postage.

If your goal is "I have text or a PDF on my computer and want someone to print, envelope, stamp, and mail it," use a print-and-mail service. USPS still delivers the letter after handoff.

Regular First Class letters generally do not include end-to-end tracking. If you need a record, choose Certified Mail. USPS describes Certified Mail as an add-on that provides proof you mailed the item and that the recipient signed for it; Return Receipt can provide a printed or emailed delivery record with the recipient's signature.

For urgent mail, choose Express instead. Express is for speed. Certified Mail is for proof. If you need both speed and a signature, review the available options at checkout before sending.
