Excellent address verification and ncoa with a clean, easy-to-maintain sdk

|PostGrid Print & Mail

Address verification and NCOA processing are legitimately good. Our returned mail rate dropped noticeably after switching. The SDK is clean and the core integration was straightforward to build and maintain.

Batch API fits cleanly into our event-driven architecture

|PostGrid Print & Mail

The batch API is exactly what we needed. We build the recipient list server-side, fire the request, and get status callbacks via webhook. The API design is consistent throughout once you understand how one resource works, the rest behave the same way. HIPAA BAA process was also smoother than I expected, which helped us get vendor approval fast.
