Sometimes it’s only obvious if you’re ‘fluent in the language’. That appalling English is no longer a clue – sender could just be too lazy to check their work before hitting ‘send’. I wouldn’t know if that Link was genuine or not.
Fortunately, DH is a computer techie and the Golden Rules are 1) Never click a link in an email, and 2) If it’s unsolicited, ask him to check it. So far, so good. I don’t know how anyone without an expert to ask survives.
