These days, you can barely browse a page on the internet without websites and businesses offering you newsletters advertising there products. Either that or offering the classic ‘We may give your details to a third party who will also bombard you with advertising emails’ tick box. You have to be so careful because some are opt-in and others are opt-out. Quite often they are rather conveniently difficult to spot and cleverly worded. If you have to, or accidentally sign up for something, then you get a constant stream of mails to your inbox. It might not be spam in the strictest sense, but sure feels like it sometimes.
Sometimes it may simply be websites you have signed up to for a promo and to receive a serial key. The common ones are the foreign language promo’s when you have to register on a website which isn’t in your native language. I still get the odd one in German or Chinese from things I registered for years ago. Also, a friend has made the ultimate mistake and let the kids use his email address a few times to register on websites and buy some things online. It’s no surprise the amount of unknown newsletters his account has been signed up for is now quite alarming!
