I switched to my custom domain for email, it works great most of the time however I would recommend against any non-traditional TLDs (e.g. .com, .org, etc) or ccTLDs (.ca, .nz, etc).
I switched to one of the new fancy gTLDs and been having issues: 1) some companies don't accept it as a valid domain; or 2) on the phone they get confused and tried add something like gmail.com to it so you get email@[email protected]
