Hi, how can I create custom email addresses for my website - i.e. [username]@[my website].com - and then how to check the email? Thanks!

Hi, you can create/check emails via your cpanel web hosting control panel.

Here is the User Manual section on the Web Hosting Control Panel: https://www.ultimatewb.com/web-hosting-cpanel-tutorials 

Please check "How To Create Your Own Custom Email Accounts" - https://www.ultimatewb.com/web-hosting-cpanel-tutorials/how-to-create-your-own-custom-email-accounts
