Medium Automation system

Message Stop Condition Layer

A guard layer for any outbound sequence that halts further messages when the contact replies, books, pays, opts out, or hits quiet hours, so automations never talk over a real conversation or break compliance.

System facts

Message Stop Condition Layer uses an event-driven automation layer for AI Automation. A guard layer for any outbound sequence that halts further messages when the contact replies, books, pays, opts out, or hits quiet hours, so automa... The architecture connects stop events, gohighlevel, make, and completed workflow with an explicit control path.

Outcome

Sequences stop the instant a human engages or opts out, which protects the relationship, honors compliance, and prevents the classic 'automation messaged me after I already replied' failure.

Main risk

An automation keeps messaging after the contact replied, booked, paid, or sent STOP, which is annoying and, for SMS opt-outs, a compliance violation.

Prevention

Evaluate stop conditions before every send, treat STOP/unsubscribe as an absolute hard stop, and enforce quiet hours and frequency caps globally.

Fallback

On any uncertainty about whether to continue, pause the sequence and assign a human follow-up task instead of sending.

How it is built

A guard layer for any outbound sequence that halts further messages when the contact replies, books, pays, opts out, or hits quiet hours, so automations never talk over a real conversation or break compliance.

  1. 01Define stop events: reply received, appointment booked, payment made, unsubscribe/STOP, or goal reached
  2. 02Add quiet-hours and per-contact frequency caps as additional hard stops on every send step
  3. 03Check the stop conditions before each message in the sequence and exit cleanly when any is met
  4. 04Tag the reason the sequence stopped and, for replies and STOPs, route the contact to the right next action
