Evolved beyond instant text messages? because that's all email is.
Honestly I hate IM tools. The threading is crap, the search is crap, the startup time is crap. there's no understanding of who can read what or what the edit history of messages are (I've been in IMs with people who will edit their messages days later to gasslight you, that alone is enough to make me hate IM apps.)

Or perhaps restrict editing, e.g. instead of being able to delete text, you can only strike through+slightly shrink+grey out text.
So if someone edited their comment three times, you would be able to read all four versions of it.
Plus they don't sit there "forever" because the archiving is usually crap.
Also it's IM. If you're going to obsess over grammar and spelling maybe just use email.
- a single window to do stuff with (so you can't really switch between two channels very easily)
- no ability to mark and unmark individual actionable messages as read
- slow as molasses client that sometimes takes seconds to react with high system load (no chance to have your own client)
- inability to integrate with self-developed tools unless you're blessed with an application token
- inability to set up advanced/granular filtering
- no user macros support beyond some primitive workflow automations
