I'm really in love with simplelogin. Since I use it I get zero newsletter, no spam at all. It hides my real email perfectly. And the best thing is: I'm not struggeling anymore if I should trust a person or a company. If they fuck up, I just click and the email alias is inactive or deleted. Easy peasy.
It's one of the best services I ever used. Once you've tried it and you've got used to it, you won't want to be without it ever again.
