Implementing SMS Keyword-Triggered Campaign Opt-In/Opt-Out Compliance Flows

What This Guide Covers

  • You will architect a legally compliant SMS messaging framework that handles automated opt-in (JOIN) and opt-out (STOP) requests without manual agent intervention.
  • You will implement logic in Genesys Cloud Architect to synchronize SMS consent status with your external CRM or Database of Record (DoR) using secure Data Actions.
  • When complete, you will have a “compliance-first” messaging pipeline that mitigates the risk of TCPA/CTIA violations while providing a frictionless experience for your mobile customers.

Prerequisites, Roles & Licensing

  • Licensing: Genesys Cloud CX 1/2/3 with SMS Messaging enabled.
  • Regulatory Approval: An approved 10DLC (10-Digit Long Code) or Short Code brand and campaign registration.
  • Permissions:
    • Messaging > SMS > View/Edit
    • Integrations > Action > Execute
    • Architect > Flow > View/Edit
  • OAuth Scopes: messaging, integrations.
  • Infrastructure: A REST API endpoint on your CRM/Database that can accept POST/PUT requests to update customer contact preferences.

The Implementation Deep-Dive

1. Understanding the Regulatory Foundation (TCPA/CTIA)

Before touching Architect, you must understand that SMS is the most strictly regulated channel in the US. The TCPA (Telephone Consumer Protection Act) and CTIA (Cellular Telecommunications and Internet Association) guidelines mandate that users must be able to revoke consent at any time via standard keywords.

The Step:

  1. Define your primary compliance keywords: STOP, QUIT, CANCEL, UNSUBSCRIBE for opt-out; JOIN, START, YES for opt-in.
  2. Configure System-Level Auto-Replies in Genesys Cloud. Navigate to Admin > Message > SMS Number Configuration.
  3. For each number, ensure the “Auto-Reply” for STOP is active. Genesys Cloud handles the “unsubscription” at the platform level (blocking future messages to that DNIS), but you must also update your CRM.

2. Architect Flow: The Keyword Router

While Genesys blocks the number at the platform level, your marketing systems may still try to send messages via API if they aren’t notified. You must use Architect to bridge this gap.

The Step:

  1. Create an Inbound Message Flow.
  2. Use a Decision block with the expression: Lower(Message.Message.Body) == "stop" or Lower(Message.Message.Body) == "unsubscribe".
  3. If True, trigger a Call Data Action to your CRM.
  4. Pass the Message.FromAddress (the customer’s phone number) and the NewStatus = "OptedOut".

[THE TRAP]
A common architectural flaw is relying only on the Genesys platform-level block. If a customer opts out via SMS but your CRM still has them marked as “Subscribed,” your marketing team might send them an email or a voice call, which can still constitute a TCPA violation in certain jurisdictions if the customer’s intent was a blanket “Do Not Contact.” Always synchronize the “STOP” intent across all contact channels in your DoR.

3. Implementing the “JOIN” Confirmation Flow

Opt-in compliance requires a “Double Opt-In” in many regions. The customer texts a keyword, and you must respond with a specific disclosure.

The Step:

  1. In Architect, check for Lower(Message.Message.Body) == "join".
  2. Use a Send Response action with the mandated disclosure text:
    “[Brand Name]: You are subscribed to [Campaign Name]. Msg & data rates may apply. Msg freq varies. Reply HELP for help, STOP to cancel.”
  3. Update the CRM via Data Action to OptedIn.
  4. Architectural Reasoning: Sending the specific “Msg & data rates may apply” text is a CTIA requirement for Short Code approval. Failure to include this in your automated response can lead to your campaign being suspended by the carriers.

4. Handling the “HELP” Keyword

Carriers require that the HELP keyword returns information about the brand and how to contact support.

The Step:

  1. Add a branch in your Architect flow for HELP.
  2. Response: “For help with [Brand] alerts, call 800-555-0199 or visit [URL]. Reply STOP to cancel.”
  3. The Trap: Do not route HELP messages to a live agent queue by default unless your staffing supports 24/7 coverage. If a customer texts HELP at 3 AM and doesn’t get a response for 6 hours, you may fail the carrier’s automated audit. Use an automated response first, then offer a “Talk to Agent” option.

Validation, Edge Cases & Troubleshooting

Edge Case 1: The “STOP” Keyword in a Sentence

  • The Failure: A customer texts “Please STOP sending me these,” but the flow only looks for exact matches.
  • The Root Cause: String comparison is too rigid.
  • The Solution: Use the Architect expression FindString(Lower(Message.Message.Body), "stop") >= 0. However, be careful-this could trigger on “I can’t stop my car!” Use regex or a more sophisticated bot intent if you expect natural language.

Edge Case 2: Multi-Campaign Conflict

  • The Failure: A customer is subscribed to “Marketing Alerts” and “Appointment Reminders.” They text STOP. Which one do you stop?
  • The Root Cause: Lack of campaign-specific keyword mapping.
  • The Solution: Use unique keywords for different campaigns (e.g., STOPMART vs STOPAPP). In your CRM Data Action, pass a CampaignID attribute derived from the Genesys SMS Number (DNIS) the customer texted.

Edge Case 3: Re-Opt-In After Platform Block

  • The Failure: A customer texts STOP (platform block), then later texts START. Genesys Cloud might still be blocking the number.
  • The Root Cause: Genesys Cloud maintains an internal “Suppression List” for SMS STOP requests.
  • The Solution: Ensure you have the “Allow Re-Opt-In” setting enabled in the SMS Number configuration. When the customer texts START, Genesys Cloud will automatically remove them from the suppression list, but your Architect flow must still update the CRM to “Subscribed.”
