Send Mail Online

API and Integration
Offer the speed and convenience of sending USPS mail online from your software platform
At LetterStream, we’ve got a little problem… we like building cool things! If you’re reading this, it probably means that you’re a software developer and you know just what were talking about! We also like to share our cool tools with others so if any of the following sound familiar, you’re in the right place.
  • I have an existing website/application in which myself or my clients need the ability to send postal mail easily.
  • I already collect payment from my clients.
  • I produce and or have electronic access to the documents that I or my clients want to mail.
  • Further, I have access to the sender/recipient data that accompanies those documents.
  • I am, or have a qualified software developer who can modify my code to sucessfully implement a web-based API.

If this sounds like your situation, give us a call!
