What LetterStream does
LetterStream is a Scottsdale, Arizona-based print-to-mail service platform incorporated as LetterStream, Inc. in 2003 and operating as a privately held, bootstrapped company with 11–50 employees. The platform allows customers — ranging from individual consumers to enterprises and SaaS platforms — to upload documents, add recipient addresses, select mailing options, and have LetterStream handle printing, inserting, addressing, and hand-off to USPS or FedEx. The underlying engine is the proprietary StreamLogic automated print-to-mail processing system, which the company claims delivers 95% of mail by the next business day (50% same day), 99.99% production accuracy, and scalability from a single piece to one million pieces per job, all backed by HIPAA-certified employees and facilities for handling Protected Health Information.
The product portfolio spans core USPS and FedEx delivery products (First-Class Mail, Certified Mail with optional Electronic Return Receipt, FedEx 2Day, Postcards, Flats, Payment Coupon Books, Statements & Invoices, Ballot Proxy Mailings) plus add-on modules including CASS and NCOA address validation, eDoc electronic delivery, EDDM marketing mail, and a PDF Tools suite (PreFlight, merge, shift, crop, rotate, extract addresses, color-to-B&W conversion). Distribution is exclusively direct: a self-serve web portal for individuals and SMBs, plus a REST API and vertical-specific integrations for SaaS embedders (credit repair platforms Client Dispute Manager and Credit Letters Generator; legal platforms appLega, Casemaster Pro, and Excela Technologies; plus QuickBooks, Google Drive, and CINC real estate CRM).
Revenue is generated on a transaction-fee, pay-as-you-go basis with no subscription, no monthly minimums, and all-inclusive unit pricing that bundles printing, processing, and postage (First-Class Letters from $1.23, Certified Mail from $8.34, FedEx 2Day from $16.35). The customer base is highly diversified across verticals — homeowner associations, property management, law firms, credit repair agencies, HIPAA-covered healthcare entities, financial institutions, nonprofits, distribution/recall companies, and embedded SaaS platforms — with no disclosed anchor customers, no disclosed funding, and no disclosed revenue figures.

LetterStream competitors and assessment
Company assessmentEmerging players
- Earth Class Mail: Earth Class Mail provides digital mailroom and mail scanning services, allowing customers to receive physical mail online. While focused on inbound mail management rather than outbound print-to-mail, it is comparable as a digital-first mail platform serving remote workers and distributed businesses.
- Postal.io: Postal.io offers a direct mail automation platform targeting sales and marketing teams with API/CRM integrations. It overlaps LetterStream's API-driven mail plus integrations model and is a comparable emerging player in sales-marketing mail automation.
Broad incumbents
- Pitney Bowes: Pitney Bowes is a long-standing incumbent in mail and shipping, offering sending solutions, mailroom equipment, and postage meters alongside outsourced mail services. While much larger and broader in scope, it competes for enterprise mail outsourcing and presort work that overlaps LetterStream's customer base.
- Doxim: Doxim provides customer communications management (CCM) and transactional mail/document delivery for financial services, utilities, and healthcare. It competes with LetterStream for regulated transactional mailings at larger enterprise scale.
- Stamps.com (Auctane): Stamps.com (now part of Auctane) is a long-standing online postage and shipping platform serving small businesses. While its primary focus is shipping labels, it overlaps with LetterStream in online postage, mailing labels, and SMB customer workflows.
Direct peers
- PostGrid: PostGrid provides an API and platform for automated direct mail, address verification (CASS/NCOA), and transactional mailings — closely mirroring LetterStream's API, address cleansing, and print-to-mail stack. It is a direct competitor in the developer/API mail automation category.
- Lob: Lob is a venture-backed API-first print and mail automation platform that lets developers send letters, postcards, and checks via REST API. It is the most direct competitor to LetterStream in the embedded/developer mail category, competing for SaaS platform integrations and transactional mail volume.
- Click2Mail: Click2Mail is an online print-to-mail service offering self-serve document upload, address list targeting, and mailing of letters, postcards, and EDDM. It directly competes with LetterStream in the SMB/individual online mailing segment with similar product breadth and pricing model.
- ClickNSend: ClickNSend is an online mailing and shipping aggregator that lets users send letters, postcards, and packages without visiting the post office. It directly competes with LetterStream in self-serve online mailings targeted at consumers and SMBs.
- Mail Technologies: Mail Technologies provides outsourced print-and-mail, digital mail, and hybrid mail services to enterprises and government agencies. It is directly comparable to LetterStream in the outsourced print-to-mail category, particularly for high-volume compliance mail.
