LetterStream sends fast, accurate, reliable mail online

Why LetterStream is Known for Sending Fast, Accurate, and Reliable Mail

With LetterStream you get speed without sacrifice when it comes to sending physical mail.

We’ll just say it: you shouldn’t have to choose between fast and accurate when sending critical mail. If your current system forces you to pick one, you’re working too hard, and your process is probably holding you back.

Whether you’re sending Certified Mail online, urgent financial notices, HOA violation letters, or medical documents, timing and precision matter. And here’s the kicker—LetterStream handles both with ease.

We’ve built our entire platform on this belief: fast doesn’t mean rushed, and reliable doesn’t mean slow. You can send real mail online and still have confidence in every envelope, every barcode, and piece of mail that we send out.

Why Accuracy Is Everything in Business Mail

Let’s be honest: a misplaced name, a missed page, or a double-stuffed envelope isn’t just a small mistake—it’s a big deal. Especially when your documents are time-sensitive or legally required.

With our intelligent document handling, every letter goes through multiple automated checks—from data validation to address formatting to barcode placement. And thanks to our proprietary The Stream technology, you get full transparency into how your job moves through the system.

You can stop crossing your fingers and start sending mail like a pro.


We Don’t Just Move Fast—We’re Built for It

Speed matters. If your team’s mailing process takes more time than it does to write the actual message, we’ve got a problem.

Most LetterStream customers go from upload to print in minutes. The best part is there’s no printing, stuffing. applying postage, or Post Office runs, just business-critical mail, handled with urgency on ours.

In fact, if it takes more than two minutes to upload a job (after learning the process and creating a job or two), it’s probably because you stopped to get a snack or more likely went to get approval from your manager about the documents you were uploading.

And with our range of mailing options—from First-Class Mail and Certified Mail to FedEx 2Day—you’re in full control of how quickly your mail gets sent out.

Reliability You Can Actually Rely On

Some platforms claim to be reliable. We prove it—millions of times over.

Whether you’re sending 10 letters or 10,000, the output doesn’t change. We don’t “hope” your letters go out. We make sure they do. We even give you updates during the production process.

That’s why businesses like law firms, healthcare providers, and HOAs trust us with their most sensitive communications.

Your team shouldn’t have to follow up on mail. With us, it’s handled.

Built for the Teams That Need It Most

We work with teams who simply don’t have time for manual errors or missed deadlines.

  • HOAs & Property Managers: Annual meeting notices, violation letters, billing statements
  • Law Firms: Time-sensitive legal notices, court correspondence
  • Healthcare Providers: Compliance letters, appointment reminders, HIPAA communications
  • Finance Teams: Late payment notices, invoices, and regulatory mail

These aren’t “nice to have” mailings. They’re critical—and they deserve a partner that treats them that way.
