Messaging overview

How brands, campaigns, and numbers fit together — and what carriers expect from every business sending SMS in the US and Canada.

The three pieces

The messaging dashboard at agency.gary.club/dashboard/messaging is organized around three objects that must each be approved before you can send:

  • Brand — the legal business behind the messaging. Real EIN, real website, real address, real support contact. One brand per legal entity.
  • Campaign — what kind of messages the brand will send (marketing, customer care, account notifications, etc.) and the sample messages that prove it.
  • Number — a long code or toll-free number assigned to a specific campaign. A number can only send under an approved brand + campaign pair.

You build them in that order: register a brand, create a campaign under it, then attach one or more numbers to the campaign once it's approved. The messaging dashboard tabs are step-ordered to match: 1. Brands2. Campaigns3. Numbers.

Who reviews what

  • The Campaign Registry (TCR) — the industry registry that scores brands, accepts campaigns, and maps numbers. Every US 10DLC brand and campaign goes through TCR.
  • Mobile carriers (AT&T, T-Mobile, Verizon and their MVNOs) — they have the final say on whether your campaign content is acceptable on their network.
  • CTIA — the trade body whose Messaging Principles & Best Practices the carriers enforce. The forbidden-content rules in this guide come from CTIA.

Timeline expectations

  • Brand verification — usually a few minutes to a few hours. A clean filing with a matching website and EIN flips to Verified almost instantly.
  • Campaign approval — usually 1-3 business days. Marketing campaigns and anything customer-data adjacent can take longer.
  • Number assignment — within minutes once the brand and campaign are approved.
  • Toll-free verification — a separate flow, typically 5 business days or less.

What the platform handles for you

  • Submitting the brand and campaign filings to the carrier on your behalf — you fill the form once, we translate it into the registry shape. Every campaign goes through our internal compliance review first; you confirm the FUEL charge before any filing leaves the platform.
  • Auto-replying to STOP, HELP, and START on every assigned number — the carrier-mandated keywords are handled before any message reaches your agent or workflow.
  • Suppressing messages to numbers that have opted out — a carrier-level requirement, enforced platform-wide.
  • Surfacing rejection reasons and resubmission paths in the dashboard so you can fix and re-file without leaving the product.

What you must provide

  • A real, reachable website for the brand whose details (legal name, contact info, what the business does) match what you submit.
  • A privacy policy on that site that explicitly states phone numbers and SMS opt-in data are not shared with third parties for marketing.
  • An opt-in mechanism — a form, paper signup, verbal capture, or inbound keyword — that captures consent the way carriers require (see Consent and opt-in).
  • Sample messages that match the use case you pick and that match what your brand actually does.
