I'm curious how CRM and lifecycle marketing teams are using enterprise LLMs (ChatGPT, Claude, Gemini) in their day-to-day work.

I don't mean using AI to write emails.

I'm interested in workflows like:

• Audience segmentation
• Campaign planning
• Journey optimization
• Trigger recommendations
• Offer personalization
• Customer clustering
• Predicting campaign performance
• Automatically generating customer segments from business requests

For teams managing email, SMS or WhatsApp campaigns, where has AI actually made a measurable difference?
