Compliance & Infrastructure

Compliance measures and a platform infrastructure that you can feel good about.

Compliance features and experts

All of Postscript’s features and list growth tools are hard-wired to follow guidelines set by the TCPA, mobile carriers, and other regulatory bodies wherever possible. As compliance regulations evolve, so does our platform to help you stay compliant automatically.

In addition, we have compliance experts, in-house lawyers, and a partnership with the TCPA Defense Force that all work together to track industry regulations, proactively notify our customers of any changes, and help answer any of your compliance-related questions. Our team has a direct relationship with the carrier networks to know about any compliance changes in advance and to negotiate for better rates on behalf of our customers.

Infrastructure and deliverability

Message deliverability and platform stability are critical parts of any successful SMS platform. At Postscript, we strive to balance compliance regulations with deliverability, thus ensuring that your messages not only follow all of the best practices, but also reach your subscribers.

Postscript pre-pays for maximum throughput bandwidth, which means sent messages will reach consumers faster. Our platform is built for scale, with infrastructure redundancies in place to handle traffic spikes (such as during BFCM). This helps ensure that even when the carrier networks are at their maximum, your message won’t get lost in the void. Thanks to sophisticated algorithms and close partnerships with both the carrier networks and our aggregator, Postscript is able to maximize throughput across both short codes and toll free numbers.
