How SMS Automation Works

We provision your number, the AI starts replying. A2P 10DLC handled for you.

1

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, then walk you through registering your business for compliant delivery.

2

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.

3

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.

4

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

Your business gets its own A2P 10DLC brand and campaign, registered under your name rather than shared with anyone else. You fill in one guided form in your portal, we handle the Twilio and carrier submission, and we email you the moment the carriers approve it. Review typically takes two to three weeks.

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 the whole A2P 10DLC submission. No Twilio console login and no dealing with the carriers directly. You give us your business details once through a guided form, and we do the rest.

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 flags the conversation for your team when it turns negative or needs attention.

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

Customer Support

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.

Local Services

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.

Post-Purchase

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.

Lead Follow-Up

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 provision a dedicated US number for you.
  • You complete one guided registration form in your portal, then we submit your business to the carriers and email you when it is approved. Review typically takes two to three weeks, and the number cannot send until it clears.
  • 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.

SMS Questions

How do I get a phone number?+
SMS is available on request. Because every SMS sender needs its own per-carrier A2P 10DLC registration, we provision SMS on a per-account basis. Request SMS access and we provision a dedicated US number through Twilio. You then complete one guided registration form in your portal, we submit your business to the carriers, and we email you when it is approved. Carrier review typically takes two to three weeks, and the number cannot send until it clears. After that the number is live and the AI starts replying to inbound SMS.
What is A2P 10DLC and why does it matter?+
A2P 10DLC is the compliance framework US carriers require for application-to-person SMS on local long codes. Numbers not registered under an A2P 10DLC campaign face heavy filtering, carrier blocks, and poor delivery rates. Your business is registered under its own brand and campaign rather than sharing anyone else's, which is what carriers expect and what keeps your delivery rates yours.
What does the AI send in an SMS reply?+
Plain text, concise, no emoji by default. The AI is prompted specifically for SMS to keep responses short (aiming for a single 160-character segment where possible). If a reply includes links, they are sent as text URLs the customer can tap. Buttons, interactive menus, and media attachments are not supported on SMS.
How do STOP and START keywords work?+
When a customer texts STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, or QUIT, ChatGenius records the opt-out, suppresses the AI, and replies with a confirmation. When they text START, YES, or UNSTOP, the system reinstates messaging. Twilio handles the carrier-level compliance in parallel. The first AI response to a new contact automatically appends "Reply STOP to opt out." to meet carrier requirements.
Is SMS included in my plan?+
SMS is available on request rather than as a self-serve plan feature, because every SMS sender needs its own per-carrier A2P 10DLC registration. Reach out and we provision your number, then guide you through registering your business with the carriers. Twilio per-message carrier fees are passed through at cost.
Can my team reply to SMS conversations?+
Yes. SMS conversations appear in the shared team inbox alongside Instagram, Facebook Messenger, WhatsApp, and Telegram. Team members claim threads, leave internal notes, tag contacts, and reply. AI steps back when a human claims. Sentiment escalation emails your team when a conversation turns negative.
Does the Flow Builder work on SMS?+
No. The visual Flow Builder supports Instagram, Facebook Messenger, and WhatsApp today. SMS conversations are handled directly by the GPT-5 AI agent with your knowledge base, tone, and escalation rules. The text-only nature of SMS means button branching would not render anyway, so the AI handles conversation logic natively.
Does SMS support MMS or media attachments?+
Not currently. ChatGenius SMS is text-only. URLs in the AI's response are preserved as tappable text links. Customers can text you images, but the AI treats inbound SMS as text-only today.
Do AI follow-ups work on SMS?+
Yes. AI follow-ups can re-engage quiet SMS leads, respecting opt-out status. Intent detection decides who to follow up with and what to say, drawing from the same knowledge base as your other channels.
