Its a scam, please delete the dodgy links. Do not click the links.
It's definitely a scam email, I've removed the dodgy links from the post.
You can tell when an email is dodgy by hovering your mouse cursor but not clicking the links you will usually see the location of the link in the bar on the bottom of your screen in this case it takes you to a site not owned by BT.
I get a lot of these emails too. Is "BRAND BOARD" a form of wording that BT ITSELF would use, because to me it is as if the scammers have deliberately corrupted BROAD BAND in order to prey on those who would just think BROADBAND without a second thought, and click on links. They say that scammers often build in a deliberate error because they know that those who are alert to spelling errors are not likely to be fooled, and are not worth the hassle of stealing from!!!
