Send business letters online: upload a PDF, we print and mail it First-Class with USPS scan updates when available. No subscription, printer, or stamps.
About Postmarkr
Postmarkr is a web-based platform that simplifies the process of sending physical mail. Users upload PDF documents, input addresses, and pay online; Postmarkr then prints, stamps, and mails letters via USPS First-Class Mail. The service verifies addresses against the USPS database, provides tracking updates when available, and ensures document security through encryption. With simple per-piece pricing starting at $2.05 per one-page black-and-white letter, it eliminates the need for printers, stamps, and trips to the post office. The platform is designed for small businesses, legal teams, property managers, and anyone who needs to send physical correspondence efficiently. Postmarkr supports up to 50-page letters and offers both black-and-white and color printing options, with additional pages costing extra. Through its integration with USPS, users can monitor delivery statuses in a dashboard. Postmarkr also offers bulk sending for campaigns, though limited to 100 recipients per order. For AiDOOS, the deployment and adoption are enhanced by its straightforward API for integrating direct mail capabilities into existing workflows, enabling automated sending and tracking without manual intervention.
