What is UserAlertX?

A cloud texting App built for one person: You, Now, Free, then Cheap!

UserAlertX is an API-first SMS product built for automations. Sign up, verify your own mobile number, and that number is the only place the platform will ever text — no directory, no bulk list, no ability to message anyone else. Your bots send a request, you get a text.
(For business or groups, see MemberAlertX.com.)

# send yourself an alert curl -X POST useralertx.com/cgi-bin/itsignup.cgi \ -d email="[email protected]" \ -d to="1112223333" \ -d from="8883861258" \ -d body="your automation finished" # change 1112223333 to your own textable number
  1. 1. You'll get a start/stop text on your phone.
  2. 2. You'll get an email asking to confirm your address.
  3. 3. Your email gets a 2FA verification request.
  4. 4. Your texts start going straight through.
  5. 5. Texting a different phone number from this account gets rejected as non-member.
Why your bot needs its own alert channel

Built around one constraint

Carriers and The Campaign Registry punish open-ended messaging. A product that can only text the opted-in owner of an account is one of the cleanest stories you can register.

01

One verified number

The recipient is always the same person who created the account and completed SMS opt-in — enforced in code, not just policy.

02

No way to spam

There's no recipient field to abuse. No marketing content, no purchased lists, no third-party recipients — structurally, not just by promise.

03

Carrier-compliant

Registered on a real 10DLC number, with full STOP/START/HELP keyword handling built in from the start.
