Mail accounts are included with every hosting package.
To be able to use these mail accounts it is possible to use them in a mail client (Microsoft Office Outlook, Mozilla Thunderbird, Windows Mail) but also webmail is possible.
The webmail for your domain can be reached under your own domain/website: [webmail.]+[domain.nl]
Let's take as an example my website can be found at welware.nl, the webmail can then be reached at: https://webmail.welware.nl
