Firstly, you don’t want an unprofessional free email address you will need to link your email to your website domain. This can be done by configuring your email via your hosting cPanel (free but restrictive) or by establishing an email web-based client like Google.
I recommend that all my clients use Google for their email provider. It only costs approx $5 and gives you access to all other Google services like Google Analytics and calendar.
We can discuss the email provider you wish to use when discussing your website needs.
