If you’re still using an email address from your internet provider (e.g. JoBloggs@talktalk.net) then this can be difficult to move.  It’s possible with some providers, but not all, and they may charge you to keep using your old address after you switch.
We strongly recommend moving to a different email provider than your ISP  – there are plenty of great free options, such as Gmail, Outlook.com or Yahoo Mail – or you could consider upgrading to your own domain name for a few pounds a year.
Changing email address can be a real hassle, but if you don’t want to be shackled to one ISP for life, sooner or later you’ll have to bite the bullet. You’ll have to let people know and update your address with any services you want to keep, but on the plus side, it’s an opportunity to cut all that annoying spam out of your life!
