you will have to upload to your web server first. If you visit web sites that offer option to subscribe to RSS feed you will probably see RSS feed address that looks similar to http://www.yourdomain.com/rss.xml
After that anyone who wants to get your content via RSS will have to copy this address to their RSS/News reader. The most popular RSS readers are http://www.newsgator.com, http://www.feeddemon.com, http://www.rssreader.com. http://www.attensa.com.
So this way people who want to get your content won't have to give you their email addresses. RSS is pull-based technology so that means that visitors need to get the content and you can't send them. That's why they can't get unwanted messages, same way when you use double opt-in for email subscriptions with a difference that using email newsletter you *send* your content and using RSS technology your members *retrieve* your content.
When you want to add new content you will upload it on your web site and add a new description to your RSS feed. Usually, publishers include only a brief description in your RSS feed with the appropriate link on their web site. However, you can include complete articles in your RSS feeds. This way you can publish your email newsletter on your web site and place the RSS. This way your subscribers will be automatically notified when you publish a new issue.
If you are email marketer it is recommended that you place a RSS button (orange is standard colour for RSS button) below your subscription form so that your visitors be aware that they can get your email newsletter in RSS format, too. Anyway, if you offer RSS, your orange button has to be highly visible on your web site, to be "above the fold". You can also include where you will give a brief explanation about RSS.
RSS technology evolves so that now you can measure how many RSS subscribers you have, you can get a click-thru ratio of each RSS feed you have, popularity of each RSS, to personalize your RSS, you can place ads like Google AdSense or Pheedo in your feeds and etc.
When you have your own RSS feeds you should promote them. We can recommend you to make a My Yahoo! and My MSN account and to list your feed URL there. When you place Yahoo! and MSN buttons (with links below) on your web site you can expect to be indexed much faster than usual.
To list RSS feed on My Yahoo!, after you have created your account click on "Add Content". After that you will see large "Find Content" field and on the right an option "Add RSS by URL". Enter your RSS feed URL and click on "Add To My Yahoo!" button. In order to enable your readers to place your feed in their My Yahoo! you have to place Yahoo! button (you can put that "Add To My Yahoo!" button but in smaller format) and link it to http://add.my.yahoo.com/content?url=http://www.yourdomainname.com/yourrssname.xml
If you want to add MSN button on your web site, place a MSN button with this link: http://my.msn.com/addtomymsn.armx?id=rss&ut=http://www.yourdomainname.com/yourrssname.xml
You can also use useful services like Syndic8, Pingomatic, Pingoat, FeedShot to promote your web site and RSS feeds to the most popular blog and RSS search engines. Also, useful site if you publish blogs or RSS feeds is FeedBurner.
