How do you (or will you) access your email?
Some people use a 'proper' email client, such as Outlook Express, Thunderbird, Windows Live Mail or similar. (That's the way that email was originally designed to be used. It's still the way that email is accessed in most workplaces and quite a few home users still prefer that method). If you use an email client you'll need to configure it with the server details to get into your email account.
However many home users now use web-based services, where they simply go to a web page via their browser (such as Internet Explorer, Edge, Firefox or Chrome) and log in from there. If you use that method to get into your email, you wont need to do anything new; you'll just be able to carry on doing what you've always done.
