10DLC Message Flow and Call to Action

During 10DLC campaign registration, you must describe your message flow — how and why customers receive your messages, from opt-in through ongoing communication.


What Carriers Are Looking For

  • How customers opt in. Website form, checkout checkbox, in-person sign-up, or keyword text.
  • What messages they receive. Types of messages (reminders, promotions, updates).
  • How often. Approximate frequency (daily, weekly, as-needed).
  • How they opt out. STOP keyword, unsubscribe link, or other method.

Good Message Flow Descriptions

Approved: "Customers opt in by entering their phone number on our website checkout page and checking the 'Receive order updates via text' box. They receive shipping notifications, delivery updates, and occasional promotional offers. Messages are sent 2–4 times per month. Reply STOP to opt out."

Approved: "New customers provide their phone number during account creation and consent to receive appointment reminders. We send one reminder 24 hours before each scheduled appointment. Reply STOP to cancel reminders."

Bad Message Flow Descriptions

Rejected: "We send messages to our customers." (Too vague — no opt-in description, no frequency, no opt-out.)

Rejected: "Marketing messages." (No context about consent, audience, or message types.)


Call to Action

Your call-to-action (CTA) is the specific prompt that triggers customer opt-in. Include it in your registration.

Examples:

  • "Text JOIN to 555-0123 to receive weekly deals"
  • "Check the box below to receive SMS notifications"
  • "Enter your phone number to get appointment reminders"
