It’s an interesting approach but I find some people who practice this end up taking up more time by needing meetings to clarify the items from the email.

I assume you mean in situations where a meeting wouldn't be necessary?

IME the opposite problem of trying to use a long email thread for things that are better discussed in a quick meeting is usually what I see people doing, far more often than the reverse.

I've developed a new policy of emailing companies from a "no-reply" email address.
