Voice of Digital Customer Success

As we begin to build our digital CS model, moving away from a named CSM, we need to establish a cohesive brand and DCS voice across channels that is personal. I'm wondering what other companies are doing when sending post-purchase CS comms without a named CSM. Specifically, what are you using as the from/sender and/or signature? With the rise of creating fictitious characters or a fictional CSM, are you moving away from generic "XYZ Customer Success" or "Your Customer Success Team"?

Examples:

• Success Team
• A fictional CSM
• CCO
• A fictional character (dog, donkey, etc.)

Would love to hear what others are doing and any learnings along the way!
