Yes and no, but the problem with (and benefit of) email is that it's a bit more formal. It's like writing a letter vs calling people.
Email threads tend to become illegible messes too, at least in the circles I'm in. Different formatting, different quote styles, and there's one email chain nowadays where the background color turned black so I can't read it without highlighting the text. There's also the thing where it's far too easy to CC people, which, granted, is a thing in Slack as well possibly but it's not yet ingrained in Slack culture in most places to make big group chats with all kinds of managers and only tangentially involved people. A lot of email is written in cover-your-ass mode with excessive formality and CCing a lot of people.
I'll take a direct message anyday when it comes to day to day stuff. I prefer important announcements, events, etc to still be in email though.
