SMS

Reach subscribers on their phones by text message. Use SMS when you want a short, timely message to land directly in a subscriber's inbox — as a standalone Broadcast or as a step inside an automation.

What you can do here

• Compose a text and send it as an SMS Broadcast to a list.
• Provision a sending number and complete carrier registration (10DLC or toll-free) before your first send.
• Set up keywords so subscribers can opt in, get help, or opt out (STOP, HELP, and more).
• Grow your texting list by inviting subscribers to text a keyword to join.
• Control when texts go out with sending windows and quiet hours.
• Add SMS steps to an automation so subscribers get a text at the right moment.
