How do I avoid SHAFT violations?

When sending SMS campaigns, compliance with carrier regulations and industry standards is critical to ensuring deliverability and avoiding fines or suspensions. Below is an overview of SHAFT violations and other restricted content in text messaging.

SHAFT Violations (Explicitly Restricted or Prohibited Content)

Mobile carriers prohibit or heavily restrict messages containing:

  • Sexual Content – Explicit or suggestive messages, adult entertainment, escort services, or sexual solicitation.

  • Hate Speech – Messages that promote violence, discrimination, or hate based on race, religion, gender, or other protected classes.

  • Alcohol – Promotion or sale of alcohol may require age verification and carrier pre-approval.

  • Firearms – Buying, selling, or promoting firearms and ammunition is generally prohibited.

  • Tobacco & Vaping – The promotion or sale of tobacco and vaping products is not allowed in SMS campaigns.

Additional Content to Avoid in SMS Messaging

  • CBD & Cannabis – Even if legal in some states, cannabis-related messaging is typically not allowed by carriers.

  • Gambling & Lotteries – Messages promoting gambling, betting, or sweepstakes often require strict compliance with legal regulations.

  • Cryptocurrency – Promotions, investment advice, or sales of cryptocurrency are often blocked unless explicitly approved by carriers.

  • Debt Collection & Payday Loans – Certain financial services, including payday loans and aggressive debt collection messaging, are restricted.

  • Pharmaceuticals & Prescription Drugs – Selling or promoting prescription drugs without proper approvals is typically prohibited.

Compliance Best Practices

  • Consent & Opt-in Compliance – Ensure recipients explicitly opt into messaging campaigns. Double opt-in is preferred for sensitive topics.

  • Clear Opt-out Instructions – Include phrases like “Reply STOP to opt-out” to comply with CTIA and TCPA regulations.

  • Avoid Deceptive Practices – Do not use misleading claims, fake urgency, or unauthorized sender IDs.

  • Proper Branding – Clearly identify your brand or organization in the message to prevent it from being flagged as spam.

By following these guidelines, you can ensure compliant and effective text messaging campaigns while avoiding violations that may result in filtering or penalties
