This structure allows you to scale your SMS program according to your budget, and you only pay for what you use.
QWhat is 'AI Infinity Testing' in Postscript?
A
AI Infinity Testing is a feature that automatically tests different variations of your SMS messages. The platform analyzes performance data in real-time, selects the highest-performing version, and optimizes your campaigns to ensure you are sending the most effective content without manual guesswork.
QHow does Postscript handle SMS compliance and security?
A
Postscript prioritizes compliance with regulations like TCPA and CTIA. It provides built-in tools for compliant subscriber opt-ins, manages opt-out requests automatically, and ensures adherence to carrier requirements.
