Online print and mail service

An online print and mail service prints, envelopes, posts, and mails a document you upload or create online. You review the printable version, enter sender and recipient addresses, choose the available mailing options, and pay before anything prints. PostalForm adds a PDF preview, address review, exact pricing before checkout, Certified Mail where eligible, bulk workflows, and API/MCP paths for software and agents.

Different jobs need different entry points. Start from the route that matches the file and volume you already have.

PostalForm reviewed 317 paid, non-scam, positive-price orders placed from January 10 through June 17, 2026. The aggregate data excludes names, addresses, filenames, unpaid orders, and suspicious orders. The full aggregate is published in PostalForm online mailing data: 2026 Q2 order patterns.

That is the shape of real one-off print-and-mail demand: mostly short PDF letters, with enough proof, color, duplex, Express, and postcard use that a service still has to put those choices in front of you before checkout.

The practical split: most online print-and-mail jobs are not enterprise mailroom projects, but they still need a real review step, because even a two-page letter can carry proof, deadline, or formatting requirements.

An API print-to-mail path makes sense when software creates the mail: recurring orders, structured recipient data, documents generated or uploaded by code, a reviewable preview, and fulfillment status you can track. For a one-off human job, the browser upload page is faster. Use the API when an application, workflow, agent, or batch process triggers the mail.

Color or black and white
Pick color for charts and branding. Black and white handles text-heavy documents at half the per-page price.

Single or double-sided
Double-sided saves paper on multi-page packets; nearly two-thirds of the 2026 orders above used it.

Delivery and proof options
Available options depend on the destination, address, document size, and provider route. For qualifying U.S. letters, First Class, Express, signature-required Express, and Certified Mail with Electronic Return Receipt may appear at checkout.

USPS is still the right path when you already have a physical letter, need to mail an original document, or need clerk help at a Post Office. PostalForm is the better fit when the starting point is a digital file or online letter and the job is "print this and mail it for me."

PostalForm is not only a consumer upload form. It also supports operational document-mail workflows:

• Bulk mail campaigns from CSV recipients and shared PDFs or templates.
• Developer API and OpenAPI documentation for quote, order, payment, and status workflows.
• Remote MCP tools for agents that need to create reviewable mail drafts.
• MPP and x402 machine-payment paths for authorized autonomous runtimes.
• AI-facing documentation at /ai, /agents, /developers, /llms.txt, and /skill.md.

Use hosted checkout when a human should review the PDF, addresses, options, and price before payment. Use direct machine payment only when the owner explicitly authorized autonomous mailing and spending limits.

PostalForm prints from digital files, so nothing goes into the envelope except the pages it prints. If you need to send physical originals, checks, keys, ID cards, physical photos, merchandise, or notarized originals, use USPS or a courier instead. And it is not legal advice, process serving, or guaranteed same-day delivery — nor a substitute for checking the mailing method your recipient requires.
