Resources

Everything you need to succeed clearly and responsibly.

BuzzPoint’s resources help teams navigate messaging compliance, optimize communications, and understand the rules that shape responsible SMS and email outreach.

10DLC Messaging

Understand the registration model behind compliant SMS.

10DLC governs how organizations use standard 10-digit phone numbers for application-to-person messaging in the United States. It exists to reduce spam, improve trust, and give carriers better visibility into sender intent.

What to know

  • The 10DLC system supports business messaging on standard long-code numbers.
  • Registration helps carriers classify traffic and enforce messaging rules.
  • Unregistered or misleading traffic is more likely to be filtered or blocked.

CTIA Guidance

CTIA best practices shape day-to-day messaging behavior.

CTIA guidance influences how organizations handle opt-in, opt-out, message content, and disclosure. Teams that understand these expectations are better positioned to protect deliverability and reduce compliance surprises.

Core themes

  • Consent language should be clear and specific.
  • STOP / HELP behavior should work predictably.
  • Operators should avoid misleading, ambiguous, or overly promotional copy.

SHAFT

Sensitive content rules still matter.

SHAFT refers to categories that raise additional carrier scrutiny: sex, hate, alcohol, firearms, and tobacco. Messages that touch these areas can face stricter controls or outright blocking depending on use case and language.

What teams should do

  • Review message copy before launch, especially for regulated audiences.
  • Make opt-in flows explicit and traceable.
  • Document internal review rules for edge-case messaging categories.

Opt-In & Opt-Out Best Practices
