I just don't check e-mail more than once per a couple of days, same as my physical mail box. Why would anybody need any additional tool for this?

I'm going to assume you just don't get a lot of emails? For many people it is the primary form of communication across a company.

It is secondary to slack/jira here, but I also dont check email more than twice a day. If something is important, someone will find me. People also know I will click tentative to meeting invites unless I have good reason to be there.
