For email at your own domain name it’s far better to use dedicated email hosting compared to piggy backing off your website hosting.
Google’s G Suite
G Suite is Google’s collection of productivity apps (Gmail, docs, spreadsheets, calendar etc.)
Using G Suite for your mail hosting gives you the Gmail interface & features on your custom domain name.
Hosted email is far more reliable than sharing with your web hosting. Sign up with G Suite below or get in touch for help migrating.
