RSS, or Really Simple Syndication, is a new way to broadcast corporate news and structured information. RSS offers a quick, easy corporate communication channel. The RSS contents are published as a feed and the feed's content keep customers, partners and journalists abreast of corporate news and information. The RSS feeds are read using a tool referred to as a news aggregator, or an RSS reader. The aggregator periodically checks to see if the RSS feed has been updated. As the feed is updated, new information will automatically appear in the RSS reader.

While RSS was at one point only considered to be a means to deliver news headlines, RSS has quickly become a powerful medium to disseminate all kinds of information. As traditional marketers are attempting to rein in content delivery, measuring e-mail open rates, click-throughs and conversions, Internet users are fighting to gain control over the content they receive. Savvy marketers and business owners are using RSS as a way to improve corporate communication and increase their external exposure and brand appeal.

What is the enclosure tag?
RSS 2.0 is quickly becoming the definitive RSS standard, all because of its support for the enclosure tag. The enclosure tag is an optional field in the RSS 2.0 specification that allows the feed publisher to include a link to a file. The file can be just about anything.

It's clear that RSS and e-mail in fact need to be used together, as opposed to either one replacing the other.

While RSS might not be used by as many people as e-mail, you can be sure that those that do use it and subscribe to your feeds will get your content without fail. In addition, many already prefer to receive information via RSS instead of e-mail, making RSS an absolute must as a supplement to e-mail delivery.
