It is absolutely impossible, that Amplify sends newsletter to anybody, who is not a member of the community and has especially signed in to receive the newsletter! Amplify is a social blogging service that makes it easy to publish, share and spark conversation around things that interest you! I am a member there, and the their newsletter can be specified! For example: the most discussed themes of the week, or the Amplogs of friends - or only new inventions on the site - or nothing of all!.! To rate this site as a bad one, because someone can not remember, what he himself has ordered, is not the quality of the site, but probably his excessive consumption of drugs!

they keep sending me news letters but to get off their mailing list you have to sign-in, hard to do when I can't remember my codes etc. honest businesses let you stop the news letter with a simple click on the bottom of the news letter. they want you to sign-in... why????
