I think it's doing a little more than that:

"Caspy’s AI learns from your email history to figure out what types of emails you send replies to. With that knowledge, it will alert you only when an email needs a reply."

But that's hardly AI. I think even Thunderbird does this, learns that emails I click links in or reply to are important and flag them as such.

Who said that an email that I typically reply to is more important for me to see than one that I typically wouldn't reply to?
