SMS Compliance Guard

Prevents STOP/HELP keyword misfires and carrier compliance fines for small SMS senders

Problem

A small team sending text confirmations and reminders for boatyards found that when a customer replied with a heart emoji, their own system scanned the compliance footer 'Reply STOP to opt out' inside the thread and misread it as an opt-out, triggering the wrong branch. In compliance-sensitive niches, this kind of edge-case bug is worse than a missing feature.

Solution

A lightweight compliance middleware: before sending, it scans message templates for keyword contamination; after receiving, it runs STOP/HELP intent detection only on the user's actual plain text rather than the whole thread, and generates compliance logs suitable for carrier audits.

Users

Small SaaS using Twilio or similar to send texts, appointment reminder services, local service providers

MVP

Connect to Twilio webhooks; classify inbound messages and flag suspected misfires; scan templates for keyword contamination before send; export compliance logs; manual review queue for misfires

Revenue

Usage-based subscription (e.g., $19/mo up to 10k messages) or per-project license

Why now

SMS remains a key touchpoint for local services while compliance rules grow more granular; big vendors won't build this edge-case protection for small teams, and an indie developer can ship it fast
