Sending Certified Mail and First Class Mail Online

Designed API First

Docsmit was designed to facilitate a new generation of mail-enabled software through our Mail as a Service.

Our REST API makes it simple to send certified mail and first class mail. Send snail mail by the thousands or a single envelope. Use our SDKs or generate JSON yourself. Either way, our USPS mail sample code and documentation makes it simple to grab a token and you'll be ready to upload an address and PDF to send snail mail.

We also make tracking certified mail easy. You can query our API for individual or summary status. Or you can use our site to get a clear summary report as well as drill down details of all deliveries and returns.
