Why This Rejection Happens
The "Opt-out Message" content you provided is incomplete or missing. Carriers require that when a user texts "STOP," they receive an immediate, automated confirmation message that explicitly states they have been unsubscribed and will receive no further messages.
Common Triggers: Leaving the "Opt-out Message" field blank, or providing a message that doesn't clearly confirm the unsubscribe action.
Root Cause Analysis
Primary Triggers
- Blank Response: The registration form asked for the "Opt-out Message" text, and you left it empty or wrote "Standard STOP response." You must provide the actual text.
- Vague Confirmation: The message says "Goodbye" or "Sorry to see you go" without explicitly confirming the unsubscribe status.
- Missing "No Further Messages": Carriers look for the phrase "no further messages" or similar to ensure finality.
Required Elements
| Element | Required Language | Rationale |
|---|---|---|
| Confirmation | "You have been unsubscribed" | Confirms the action was successful. |
| Identity | "[Brand Name]" | Confirms WHICH list they left (Code 5100). |
| Finality | "No further messages will be sent" | Legal assurance of compliance. |
Step-by-Step Remediation
Draft a Compliant Response
Create a message that meets all carrier requirements. Keep it under 160 characters if possible.
✓ Compliant Template
"You have successfully unsubscribed from [Brand Name]. You will receive no further messages. Reply HELP for help."
✗ Non-Compliant Template
"Ok, we stopped."
(Too casual, missing brand & finality clause)
Configure Your Platform
Log in to your SMS provider (Twilio, etc.) and update the automatic response for the "STOP" keyword with your new compliant text.
Update Registration Data
Copy the exact text you configured and paste it into the "Opt-out Message" field in the TCR portal.
Carrier-Specific Requirements
T-Mobile
- Requires the opt-out confirmation to be the final interaction. Sending anything else after this message is a violation.
AT&T
- Looks for the specific phrase "no further messages" or equivalent. Without it, the opt-out process is considered ambiguous.

Common Mistakes to Avoid
❌ "We'll miss you!"
Avoid emotional or "guilt-trip" language. Keep the confirmation transactional and professional.
❌ Marketing in Opt-out
Never try to resell to a user who just quit. "You unsubscribed. Reply DEALS for 20% off" is a severe compliance violation.
