Configure text, URL actions, alignment, and styling. Behavior and appearance vary by channel, with limited support in SMS/chat. Action Blocks add interactive buttons or links to your notifications, letting recipients take action directly from the message. They render as buttons in email and as plain URLs in SMS and chat channels. New Action Block
