The short answer.

Prepare the document as a US Letter PDF, check every page, confirm the sender and recipient addresses, then choose where it will be printed and mailed. You can print it yourself, use a local print shop, or upload it to an online print-and-mail service such as Iris Postal Forms. Iris shows the configured price before checkout, prints the approved file, and submits the mailpiece to USPS.

Check the page size and margins

Use 8.5-by-11-inch pages for a standard US Letter document. Review the PDF at full size and make sure names, signatures, account references, and page numbers are not clipped.

  • Open every page before upload
  • Remove blank pages you do not intend to mail
  • Confirm that fonts and images render correctly

Choose single-sided or double-sided printing

Single-sided printing is easier to review and may suit formal notices. Double-sided printing reduces the number of sheets. Check the service preview because page count, sheet count, color, and print sides can change the price.

Verify both mailing addresses

Enter the complete sender and recipient addresses, including apartment or suite information. Address suggestions are useful, but the sender remains responsible for checking the final address before payment.

Choose a printing and mailing route

A home printer gives you direct control but requires paper, an envelope, postage, and a USPS handoff. A library or print shop handles the printing, but you still assemble and mail the letter. An online service combines printing, addressing, payment, and USPS submission in one browser workflow.

Select tracking only when the document needs it

Ordinary First-Class Mail may be enough for routine correspondence. If you need a mailing receipt and carrier tracking, review the available Certified Mail options and the current USPS terms before checkout.

Can I mail a PDF from my phone?

Yes. If the PDF is stored on your phone or a connected cloud drive, an online print-and-mail service can accept the upload through a mobile browser.

Does the PDF need to be US Letter size?

A standard letter workflow usually expects 8.5 by 11 inch pages. Check the selected service requirements before uploading a different page size.

Where do I see the final price?

Iris calculates the price after you add the PDF, addresses, and mailing options. Review that itemized price before payment.
