How SMS Automation Works
We provision your number, the AI starts replying. A2P 10DLC handled for you.
Request a US Number
SMS requires per-carrier A2P 10DLC registration, so we set it up with you. Request access and we provision a dedicated US number through Twilio, registered for compliant delivery.
AI Replies on Inbound
Twilio forwards every inbound SMS to ChatGenius (with Twilio signature validation on every request). The GPT-5 agent reads the message, checks your knowledge base, and responds. Keep replies short (SMS character limits) is part of the SMS system prompt.
Opt-Out Enforced by Default
STOP, UNSUBSCRIBE, CANCEL, END, and QUIT all trigger an opt-out. The first AI reply to any new contact includes "Reply STOP to opt out." to meet carrier compliance. START, YES, or UNSTOP re-enable messaging.
Team Steps In When Needed
Sentiment escalation flags negative threads, your team claims the conversation from the shared inbox, and they reply directly. The AI backs off for that thread until the team releases it.
SMS Features
What works on SMS today, verified against the code
GPT-5 AI Agent (SMS-Tuned)
Same AI brain, knowledge base, and tone as your other channels, with SMS-specific formatting built in: extremely concise replies, no emoji by default, no unnecessary links, and respect for SMS character limits (Twilio concatenates multi-segment messages automatically).
A2P 10DLC Compliance
Every number you purchase is automatically added to our Twilio Messaging Service, which carries A2P 10DLC campaign registration. You skip the weeks-long carrier registration process most businesses have to figure out on their own.
STOP / START Keyword Handling
Six stop keywords (STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, QUIT) and three resume keywords (START, YES, UNSTOP) are enforced automatically. The first AI reply to each new contact appends a carrier-required opt-out footer.
Done-For-You Number Provisioning
We provision your dedicated US number and handle the Twilio setup and A2P 10DLC registration. No Twilio console login, no carrier registration paperwork on your side.
Shared Team Inbox
SMS conversations appear alongside Instagram, Facebook Messenger, WhatsApp, and Telegram in one inbox. Claim, tag, add internal notes, and assign agents. AI steps back when a human takes over.
Lead Capture & Escalation
Names, emails, and additional phone numbers shared in an SMS conversation are auto-extracted into the unified lead view. Sentiment escalation fires an SMS alert to you when a conversation turns negative or is flagged.
AI Follow-Ups
Automated follow-ups re-engage quiet SMS leads while respecting opt-out status. Intent detection decides who to follow up with and draws from the same knowledge base as your other channels.
Twilio Signature Validation
Every inbound webhook request is verified against Twilio's X-Twilio-Signature header before processing. Forged webhooks are rejected at the door, not somewhere deep in the pipeline.
Knowledge Base & Business Context
The SMS agent answers from the same RAG knowledge base as your other channels, so product, pricing, hours, and policy questions get the same answers via SMS as they would via Instagram or WhatsApp.
What SMS does not do
Setting expectations upfront keeps launches smooth
SMS is a text-only carrier channel, so a few features from your other channels do not apply:
- Visual Flow Builder does not currently run on SMS. The AI agent handles conversation logic directly.
- Buttons, quick replies, and interactive menus cannot render over SMS. If the AI wants to include links, they arrive as tappable text URLs.
- MMS and media attachments are not supported today. SMS is text-only.
- WhatsApp templates and broadcasts are WhatsApp-specific. Outbound SMS campaigns are handled through the standard Twilio send path.
- Comment-to-DM, AI Comment Manager, Content Studio, and AI Media Library are features for Meta channels, not SMS.
Use Cases
Text-Based Help Desk
Customers who prefer SMS over email or app chats get a GPT-5 agent that answers product, shipping, and account questions 24/7, backed by your knowledge base. Complex threads escalate to a human.
Appointment Reminders & Confirmations
Your AI confirms appointments, handles reschedule requests, and gets a quick reply from customers. Google Calendar sync and the integrated booking engine handle the slot work.
Order Updates & Review Requests
Send thank-you texts, follow-up messages, and review requests with AI-powered personalization. STOP keyword opt-out is handled automatically, so customers are never spammed.
Quick Response to New Leads
Lead captures name + phone on Instagram, continues the conversation over SMS. Same AI, same knowledge base, same lead record, same inbox.
How to Get SMS
SMS is available on request, enabled per account
Because every SMS sender needs its own per-carrier A2P 10DLC registration, we enable SMS on a per-account basis rather than as a self-serve plan feature:
- Request SMS access and we register your business and provision a dedicated US number.
- A2P 10DLC compliance, STOP/START opt-out handling, and webhook setup are handled for you.
- Your SMS conversations join the same shared team inbox as your other channels.
- Twilio per-message carrier fees are passed through at cost and billed to your Twilio subaccount.
