To use webmail for domain-based email accounts, you must first configure the accounts through your hosting account. To get it done, follow these steps.
Log in to your cPanel account—an all-in-one HostFast control panel—by visiting www.domain.com/cpanel, of course, replacing domain.com with your domain name.


On the dashboard, locate the Email section and click Email Account to begin creating your email account.

Choose your domain and enter your email address.
Type your password, confirm it, or use the ‘Generate’ button to generate a strong password automatically than Click ‘Create’
And done now you can use your professional email account.
