It’s important to note that there are two subgenres of WP hosting: WordPress.org and WordPress.com. The latter is a free, fully-hosted site that allows you to build and host basic website with the people who created the platform. Although the WordPress hosting platform is on its way up, it’s not yet the ideal option for folks who are looking to run a business site or aspire to grow a substantial web presence. If you’re doing anything more than posting your resume or blogging your ideas, you want WordPress.org hosting.
That said, not all web hosts offer email. WP Engine, for example, does not. In such instances, you must email accounts from a company other than your web host. GoDaddy, for instance, sells email packages starting at $3.49 per user, per month. That might sound like a hassle, and just one more thing to keep track of, but there are actually some webmasters who feel that separating your email hosting and web hosting services is smart. That way, one provider going offline won't completely bork your business.
If you aim to have a web presence, you've got to have email. It's a convenient way for potential customers and clients to send you a message, Word document, or other files. Thankfully, most web hosts include email in the price of their hosting plans. Some web hosts offer unlimited email account creation (which is great for future growth), while others offer a finite amount. You, naturally, should want unlimited email.
