How Using LetterStream’s API Saves Companies Time, Money, and Sanity

LetterStream’s API allows companies to automate business-critical mail.

Behind every successful operations team is one core truth: they didn’t get there by printing and stuffing envelopes by hand.

Automation has become the backbone of modern business operations, especially for teams managing recurring or high-volume mail. And if you’ve ever wished you could hit “send” on a document and have it magically turn into trackable Certified Mail or just a First-Class letter… you’re closer than you think.

With the LetterStream API, developers and operations leaders can fully automate the printing, processing, and sending of snail mail, securely and efficiently.

Here are five real-world use cases that show how the LetterStream API saves time, reduces stress, and helps teams work smarter (not harder).

1. Automate Late Payment Notices from Your CRM

Still sending out manual past-due letters? With the LetterStream API, you can connect your CRM or billing platform to automatically trigger a physical notice after a set number of days.

Let’s say a customer hasn’t paid within 30 days. Your system can generate a PDF notice, ping the LetterStream API, and send the letter via First-Class Mail—without anyone printing or folding a thing.

Need to add Certified Mail for legal protection? You can include that logic too. Tracking numbers, digital proofs, and delivery data all included.

This is how finance and AR teams turn chaos into consistency.

2. Trigger Mailings from Your Internal Software

Whether you’re using custom ERP tools, a ticketing system, or something built in-house, if it can send a webhook or make an HTTP request, it can send mail through LetterStream.

Imagine this:

  • An eviction notice is triggered when a resident’s file status changes
  • A violation letter goes out when a photo is uploaded in your HOA software
  • A legal firm’s case management system auto-generates and sends a filing notification

If you’ve got software that manages workflows, you’ve got the power to connect it directly to our print and mail software—and make the paper part disappear.

3. Bulk Job Scheduling and Batch Mail

Need to send 500 notices each Friday? Or maybe you’re processing thousands of monthly statements for clients?

With the LetterStream API, you can script and schedule batch jobs that send all your mail at once, pulling from databases, applying templates, and routing based on zip code or content.

You stay in control, and your team avoids the last-minute, end-of-month stress. Plus, you’ll always have a full audit trail to reference, including file uploads, job IDs, and delivery confirmations.

Pair this with StreamLogic™, and you can build in automated logic to handle special rules, like Certified Mail for certain states or alternate return addresses for specific regions.

4. Empower Your Customers

If your business offers SaaS tools to other companies—think property management platforms, legal software, or fintech tools—you can integrate the LetterStream API directly into your platform.

That means your users can send Certified Mail or First-Class Mail without ever leaving your website.

You get:

  • Embedded mailing capabilities
  • Brand consistency (you can white-label the experience)
  • Zero support tickets about printers or postage

We handle the print, insert, and send. Your platform gets the credit. Everybody wins.

5. Create a Compliance-First Mailing System

If your industry deals with HIPAA, legal timelines, or regulatory disclosures, the API allows you to bake secure, traceable mail delivery into your compliance workflows.

No more guessing if something was sent. No more “we thought the admin handled that.”

Every job has a digital record, every piece of Certified Mail is trackable, and you can see when it was mailed from our end.

For healthcare groups, law firms, and insurance providers, this turns compliance from a risk into a repeatable system.

Let Your Systems Do the Sending

The best part? Your team can stop wrestling with stamps and focus on work that actually moves the business forward.

When physical mail becomes just another API call, everything gets smoother: timelines, compliance, customer experience, and morale.

LetterStream’s 2025 Q1 Bonus Party at Snakes & Lattes!

Woohoo! It’s bonus party time again at LetterStream!

On Wednesday, May 21st, the LetterStream team headed to Snakes & Lattes in Tempe for our quarterly bonus celebration. The theme? Olympic Board Game Night. The vibe? Energized, connected, and a little competitive (in the fun way).

Let me tell you how it went.

A Night of Teamwork

We split into teams, grabbed some game boards, ate some food, sipped on yummy lattes, and dove in. No printers, no tracking numbers—just great people, games, and a lot of laughter.

Some teams came to win. Others just came to eat delicious food and roll dice. Either way we got to be together as a work family.

The board game “Olympics” wasn’t just a clever name—it turned into an actual team showdown, with rounds of strategy, bluffing, guessing, and cheering each other on.

We didn’t crown a champion, but let’s just say some teams walked away feeling very accomplished.

Food, Lattes, and That Off-the-Clock Magic

Snakes & Lattes was the perfect setting. Chill atmosphere, excellent menu, and enough coffee to keep us wide awake even after the longest round of Monopoly.

More importantly, it gave us the chance to catch our breath and catch up. These quarterly parties aren’t just about having a good time—they’re also about being together. Getting to talk about something other than mail job or turnaround times. It’s about saying thank you for the hard work that each team member puts in day after day, quarter after quarter, year after year. And a little bit about finding out who’s really good at trivia. Or who’s been quietly training for this moment their entire board-game-loving life. We’re here for it all.

Celebrating Accountability, LetterStream-Style

Each quarter, we highlight a core value, and this time, it was Accountability.

Just like every other bonus party we had a great slideshow to represent the last quarter and showcase our progress and even ways we can continue to improve. We also take the time to recognize new team members, highlights, promotions and new changes. We love to recognize that our team shows up for each other, owns their part of the process, and keeps things moving when it matters most. Q1 demanded that and our team delivered.

Like we mentioned above, this party was our way of saying thanks— in real time, with real connection and of course, with lots of really fun times!

Until Next Time…

To everyone who helped make the night happen—thank you. For showing up, playing along, and being the kind of team people are proud to be part of.

Q1’s in the books. Q2, we’re coming for you—with a little caffeine and a lot of momentum!

Top Reasons Franchises Are Outsourcing Printing and Mailing for Faster Growth

Franchise owners have a lot on their plate, from managing multiple locations to keeping operations running smoothly. When it comes to essential communications—whether promotional materials, invoices, or important legal documents—efficiency and accuracy are critical. However, handling printing and mailing in-house can be a time-consuming and a resource-intensive process. That’s why many franchises are turning to outsourcing, allowing them to focus on what they do best: growing their business.

Here’s why outsourcing bulk print and mail needs is becoming a popular choice for franchises:

Let the Experts Handle It

Managing the logistics of printing and mailing can quickly become overwhelming. From printer malfunctions to managing supplies and ensuring timely deliveries, it can be a significant drain on internal resources. Franchisees already juggle enough daily responsibilities, so adding print and mail operations to the list only adds complexity.

Outsourcing to professionals removes this burden, leaving the intricate processes of printing and mailing to experts. This ensures that your materials are produced and sent out efficiently, with minimal hassle. Instead of spending time on admin tasks, franchisees can focus on delivering excellent service and growing their business.

Cost-Effective Solutions

While it might seem more cost-effective to handle printing and mailing in-house, the reality is that expenses can add up quickly. Printers, paper, ink, maintenance, and dedicated staff all come with a price tag. And when something goes wrong—like a printer breakdown—the unexpected costs can be significant.

Outsourcing often provides a more affordable option, especially for franchises that need high-volume mailings. Professional services can offer bulk pricing and eliminate the need for constant maintenance. By outsourcing, you can cut operational costs while still receiving high-quality, professional results.

Speed and Efficiency

Franchises thrive on efficiency, and when it comes to getting time-sensitive and important mailings out the door—whether statement and customer communications, signed ownership documents or tax documents—speed matters. Managing this process in-house can lead to delays and inefficiencies, especially when coordinating across multiple locations.

Outsourcing ensures that all your printing and mailing needs are handled promptly and professionally. With the right provider, you can trust that your materials will be processed and sent out quickly. This allows your franchise to run smoothly and meet tight deadlines without added stress.

Pro tip: If you want to get your mail delivered the fastest way possible, you can choose FedEx 2Day with a signature confirmation. That way if gets your mail there fast and you can track. Another option for tracking would be Certified Mail and you can also choose Certified Mail with an Electronic Return Receipt to get proof of delivery.

Compliance and Security

Franchises often need to deal with sensitive documents such as legal notices, financial disclosures, or regulatory forms. Ensuring these communications are handled correctly is crucial, as any errors could lead to compliance issues or security risks.

Outsourcing your printing and mailing to a trusted provider ensures that these important documents are processed securely and in accordance with legal standards. These providers are well-versed in data privacy and compliance regulations, so you can rest assured that your documents are being managed appropriately and securely.

Focus on Growth, Not Admin

For franchise owners, the goal is always growth—expanding locations, improving customer service, and increasing profits. By outsourcing non-core tasks like printing and mailing, franchises can reallocate their time and resources to focus on achieving these bigger business goals.

Outsourcing doesn’t just reduce the administrative burden—it enables franchisees to run more efficient operations. With printing and mailing handled externally, franchise owners and managers can concentrate on strategic priorities that drive long-term success.

LetterStream is a printing and mailing company, offering bulk printing and mailing services for businesses of all sizes from those with small business mailing needs to Fortune 500 companies that want to send mail online.
