Email newsletters are great, but spam is not. The deluge of junk mail has made it increasingly painful to follow the news and what's happening on your favorite web sites via email.
Either the newsletter you're eager to read is hidden in a massive spam attack or it does not arrive because your ISP is blocking spam and your favorite newsletter falls victim to the filters, too (now you know why a "false positive" is something negative).
RSS Feeds as an Alternative to Email Newsletters
Fortunately, there is an alternative way to subscribe to the web sites and blogs you visit regularly: RSS.

RSS stands for Really Simple Syndication or Rich Site Summary (of course, the acronym can be explained in many other creative ways), and it allows you to "syndicate" news summaries from web sites.

You can use these syndicated RSS "feeds" to display the latest news from major newspapers, for example, on your own web site or read them on other sites collecting these feeds.

And There's no Spam
But you can also display RSS feeds on your desktop and use them like email newsletters. There are special programs and web-based services called "RSS feed readers" or "RSS aggregators" that, given the URL of an RSS feed will fetch the latest headlines periodically and let you read them comfortably and efficiently (avoiding the info glut so common today).
The best thing about RSS is that if you subscribe to an RSS feed, you only get what you want. If you tell the feed reader to stop collecting a site's feed, it will stop. And there's no spam.

And there's no spam!
