Two are Gmail based and one is Yahoo based. I’ve got emails from years ago all over the place. I’ve got three email accounts all syncing to my devices. Let’s just start with me saying my current email solution is in a right mess. So what do you do? You set up a new email account with a more appropriate account name, then when you get a new ISP, then you get another email address so and so on and so on.
Remember all those years ago when you’ve got your first email account and you couldn’t wait to set it up with a stupid account name? Now, many years later, it’s quite embarrassing having to pass those details to any prospective employers, hospitals or friends.
