UserAlertX
UserAlertX is an API-first SMS and email alert product enables AI agents, bots, and scripts to send messages to one verified phone number.
UserAlertX is an API-first SMS and email product designed for AI agents, bots, and programs to send text and email alerts to the account owner. Users sign up and verify their own mobile number, which remains the sole destination for all platform messages. The service features 10DLC registration, carrier compliance, and automatic handling of STOP, START, and HELP keywords. When an alert contains topics restricted by phone carriers, such as stocks, trading, cryptocurrency, or loans, the system delivers the complete message by email and sends a short notice to the phone instead. Setup involves confirming an email address and replying to a text message.
