It usually doesn’t happen very often but sometimes we need to change our email address. Whether it’s a change of name, circumstance or, for varied reason, have lost access to our original email, it can happen. It could be for personal safety reasons.
I’ve just done this and switching email was painless. However, letting every website that you’ve registered with know about it, isn’t. Technically, it should be – you can change your email, right? In most cases, yes. In some cases no, but there’s a solution. But for a few sites – including large UK retailers – it’s a big “no”. It’s a security risk (I’ll explain why in a bit) and they won’t given an explanation as to why they do it either.
