What Is An Enterprise Email Hosting & Its Benefits?

That's not a standard term. Better ask the one who uses it.

In general, anyone who offers a mail server to a company with the company's domain name and different users in that domain, like mary(at)mycompany.com and john(at)mycompany.com, can use that term.
Common examples are a lot of companies offering 'hosted exchange' or google's 'gmail for work'.

The advantage is that the company doesn't have to run its own e-mail server.

Email hosting services are usually premium services which differ from the typical free webmail sites such as Yahoo and Google. These hosting providers cater to more demanding users like high-email-traffic small- and medium-sized businesses (SMBs) that require their own domain name in order to distinguish them more.
