How to Send a Physical Letter from Your Computer: Step-by-Step Tutorial

Sending a physical letter no longer requires printers, envelopes, or a rushed trip to the Post Office. Today, you can upload a document from your computer and send real mail online quickly, accurately, and reliably. This guide walks you through the process step by step so you can mail important documents without leaving your desk.

Why Sending a Letter Online Is So Simple Now

In the past, mailing a letter meant printing, folding, stuffing, applying stamps, and hoping everything worked correctly. Then it meant driving to the Post Office and waiting in line for what can seem like forever. Modern print-to-mail tools replace all that effort with a cleaner digital workflow. You upload your file, choose your mailing options, and the system prints and sends your mail for you.

This process is powered by controlled workflows—like The Stream—which keeps each piece of mail moving quickly, accurately, and reliably, and it’s what allows 94% of mail at LetterStream to go out the next day.

Here’s a breakdown of how The Stream at LetterStream works:

Step 1: Prepare Your Document

Start by saving your letter as a PDF. PDFs work best because they preserve formatting and ensure your mailed letter looks exactly as intended. If you’re sending statements, notices, or legal documents, double-check that your formatting is clean and readable.

A quick review now prevents address issues, formatting problems, or missing pages later.

Step 2: Upload Your File to a Print-to-Mail Platform

Next, log in to a platform like LetterStream and upload your PDF. You’ll see prompts to confirm the address, choose your mail class, and decide whether you need tracking. Because everything is handled online, you avoid equipment hassles, supply runs, and last-minute printer issues.

Step 3: Choose How You Want the Letter Sent

From here, you choose the type of mail that fits your needs. You can send:

Each option helps you send mail online without touching physical envelopes or supplies.

Step 4: Review and Approve Your Letter

Before sending, you’ll see a preview of your document. This step lets you confirm:

  • The correct address appears in the windowed envelope
  • All pages are included
  • Your formatting looks right
  • You selected the correct mail class

Once everything looks good, click send. The Stream takes over from there—printing, preparing, and routing your mail through the appropriate mailing channel.

Step 5: Track and Manage Your Mail Online

After sending your letter, you can log in anytime to track its progress. This helps you confirm when your mail is processed and when it’s been mailed. For Certified Mail and FedEx 2Day, tracking provides added assurance that your document was sent and handled correctly. You can also opt for a Certified Mail Electronic Return Receipt, which requires a signature when the letter arrives at its destination. This can all be tracked and seen in your dashboard.

Why More Businesses Mail This Way

Sending mail online supports efficiency, especially for organizations that send recurring or time-sensitive communications. Teams avoid equipment issues, reduce administrative labor, and send mail quickly, accurately, and reliably. Whether you’re mailing invoices, notices, statements, or legal documents, the entire workflow becomes easier.

Fast, Accurate, Reliable Mail

Mailing a physical letter no longer requires manual effort. With modern print-to-mail tools, you can upload a document, choose your options, and let the system print and send your letter with speed, accuracy, and reliability. Whether you’re mailing a single notice or managing high-volume communication, sending mail online keeps your workflow simple and efficient.
