Market validation - would you use AI-first email client?

Hi, my friends built a tool and I'm a fan of it, so I thought I'd help them spread the news :) 

https://blinkfeed.ai is an email client that displays email summaries instead of threads (you can still view the thread if you want to), allows for one-click replies, and provides the best AI/UX experience I've seen in this space.

While there are a bunch of tools that allow you to create summaries and help write replies, Blinkfeed's UI/UX was built around these concepts, delivering something far more refined than anything I've seen.

The question is – would you use tool like that? If yes, why? If not, why not?
