I currently still use Gmail, but I am looking to move away. I recently signed up for simplelogin.io and purchased a cheap domain name to use with it. I then went around changing my Gmail email address to a different email alias for each and every site I use. It's a lot of work and I found some sites you can't change the email address, they refuse to allow email aliases or you have to contact support to get them to change it. All a pain. For the majority though most are now on my own domain's email address and all point to my Gmail inbox. At least now when I do switch I have done the hard work and only need to update the email address in simplelogin. Since I use my own domain, I shouldn't lose access to the email account should I need to move it away from simplelogin.
