For better or for worse (I think to some degree, worse) I've found Slack has eliminated about 90% of my email use at work. My work email is almost all automated emails, communications with people external to the company, and a small percent of internal communications. Nearly everything else is done over Slack. So in my experience, it certainly is replacing email. Now, I'm not sure that it should. But it is.
