CTA Consent Mechanism Insufficient
Why This Rejection Happens
The vetting agent (typically from Twilio or The Campaign Registry) reviewed your Call-to-Action (CTA) and determined that the mechanism for collecting consent is weak, broken, or non-compliant with TCPA standards. The opt-in method described does not prove that the user explicitly agreed to receive SMS messages.
Common Triggers: Relying on "implied consent" (e.g., they bought a product), using a pre-checked box, or hiding the consent language in a Terms of Service link.
Root Cause Analysis
Primary Triggers
- Pre-checked Box: The opt-in checkbox on your web form is checked by default. This is illegal under TCPA for marketing messages; the user must take an affirmative action to check it.
- Bundled Consent: The consent is bundled with other agreements (e.g., "I agree to Terms & Conditions and SMS marketing"). SMS consent must be unbundled and distinct.
- No Checkbox: You are collecting marketing consent via a web form but have no checkbox at all, just a disclaimer. For marketing, "Express Written Consent" usually requires a checkbox.
Required Elements
| Element | Requirement | Why? |
|---|---|---|
| Checkbox State | Unchecked by default | Proves user intent. Pre-checked boxes are considered "passive" and invalid. |
| Placement | Distinct from T&C | User must agree specifically to SMS, not just general site terms. |
| Action | Affirmative | User must physically click or type to join. |
Step-by-Step Remediation
Uncheck the Box
Go to your form settings. Ensure the SMS opt-in checkbox is empty by default. The user must click it.
Separate the Consent
If you have one checkbox for "Terms, Privacy, and SMS," break it up. Create a standalone checkbox just for SMS.
✓ Compliant
🔳 I agree to receive marketing SMS from [Brand]...
🔳 I agree to Terms & Conditions...
✗ Non-Compliant
🔳 I agree to Terms, Conditions, and SMS Marketing.
Update Screenshot Evidence
Take a screenshot of the corrected form showing the unchecked box and distinct consent language. Upload this to the portal.
Carrier-Specific Requirements
T-Mobile
- Aggressively rejects "bundled" consent. SMS consent must be a separate, voluntary choice, not a condition of purchase or service.
AT&T
- Focuses on the "Call-to-Action" description. If you describe a "soft" opt-in (e.g., "users join by emailing us"), they will flag it as insufficient for recurring campaigns.

Common Mistakes to Avoid
❌ "By entering your number..."
For marketing, simply typing a number isn't enough if the disclosure is hidden. You need a checkbox to prove "Written Consent" was given knowingly.
❌ "Double Opt-in" Confusion
Double Opt-in (replying "Y" to a text) is great, but the initial web form still needs to be compliant. You can't use a bad web form just because you have DOI later.
Expected Timeline
This guidance provides general information about 10DLC compliance requirements. Strong consent mechanisms protect your business from litigation and high opt-out rates. Organizations should prioritize "Express Written Consent" for all marketing traffic. MyTCRPlus does not provide legal advisory services or regulatory representation.
