But that's what sorted by date means, right? When you get a new mail, it goes at the top of the mailbox, and after new ones arrive, it goes down.

My mailbox sorted by date is a total mess. Having everything grouped by sender email would automatically make it tidy.

That works for single-sender mails, but most of my work mails have almost a different sent of contacts per topic. Grouping mails by subject (topic) makes this more manageable.

In all mail clients I've used, you're 1 or 2 clicks away from seeing your unread messages only, which greatly helps with filtering what's important to read soon.
