Does every outbound text need to be the same, or can they be personalized?

Outbound Text Personalization and Incoming Response Options

When sending outbound text messages, the process is standardized, but there are several options to personalize the content. Users can incorporate variable information that will dynamically display the recipient's name, agent name, phone number, address, or any other unique data. For incoming responses, agents have the flexibility to utilize pre-written replies to address common scenarios or compose freeform responses that allow for fully customized messaging.
