Why This Rejection Happens

The automated response message sent to users when they text "STOP" does not identify the brand name. Carriers require that the final confirmation message explicitly states which service the user has unsubscribed from to confirm the action was successful.

Common Triggers: Using a generic "You have unsubscribed" response instead of "You have unsubscribed from [Brand Name] alerts."

Root Cause Analysis

Regulatory Framework: CTIA Messaging Principles (Opt-Out Confirmation)

Primary Triggers

  • Default Configuration: Many SMS platforms (Twilio, Vonage, etc.) have a default STOP response like "You have successfully unsubscribed." This default is non-compliant for 10DLC brands.
  • Brand Name Omission: The response is customized but simply says "Unsubscribed from updates" without naming the specific company.
  • Character Limits: Trying to save money/space by cutting the brand name from the confirmation text.

Required Elements

Element Requirement Example
Confirmation Confirm Action "You have successfully unsubscribed..."
Identity Brand Name "...from Joe's Pizza alerts."
Finality No further messages "You will receive no further messages."

Step-by-Step Remediation

1

Locate Keyword Settings

Log in to your messaging provider dashboard. Find the settings for "Keywords" or "Opt-out Management." Look for the configuration for the keyword STOP.

2

Customize the Response

Edit the automated reply message. Ensure it follows the format: [Confirmation] from [Brand Name].

✓ Compliant Response

"You have been unsubscribed from North Star Logistics. No further messages will be sent. Reply HELP for help."

✗ Non-Compliant Response

"You have unsubscribed. Goodbye."

Update TCR Sample

Go to your TCR campaign registration. Ensure the "Opt-out Message" field matches exactly what you configured in Step 2. Mismatches between the registration data and actual behavior can cause audits to fail.

Carrier-Specific Requirements

T-Mobile

  • Strictly enforces the presence of the Brand Name in the STOP response. This is a primary check for their vetting process.

AT&T

  • Requires the opt-out confirmation to be the final message. Do not send a "Sorry to see you go, here is a coupon" message afterwards. That is a violation.

Pre-Resubmission Checklist

  • The "Opt-out Message" field contains the Brand Name.
  • The Brand Name matches the registration (Code 2006 check).
  • The message confirms the unsubscribe action.
  • I have configured this response in my actual messaging platform.

Common Mistakes to Avoid

❌ Leaving it Blank

Some platforms allow you to leave the custom response blank to use the "system default." Never do this. Always customize it to ensure the Brand Name is present.

❌ Marketing in the STOP Message

Do not try to win them back in the STOP response. "You unsubscribed. Reply JOIN to get 10% off" is risky and often flagged as ignoring the opt-out.
