1. Keep in touch with your customers and subscribers:
You don't have to send emails every day or week ... A bimonthly or monthly newsletter is very nice way of keeping in touch with your clients and subscribers.
You can send information like -
* articles
* announcements
* free resources
* related products
* new products
* free upgrades
* Just to say 'hi' newsletters ...
etc
Your subscribers remember you and keep their memory fresh about your product or company. The newsletters bring your subscribers back to your web site once in a while. This is a good thing that they will checkout your new products or they might use 'Tell a friend' script on your site.
2. Brand Yourself as an expert:
The more you talk about your niche the more you will be recognized as an expert. Talk about things like -
* research that is going in your niche
* updates
* technical issues
* your experiences
* your opinions
Print your subscription url on your business card and distribute them at local business places or friends.
3. Publish on your site to increase content:
Not only send the newsletters but publish them on your site. As most of these newsletters have content around your niche, these content pages are keyword targeted which attract the search engines.
While sending articles in newsletters, remember few things-
* let the content be around your web site niche
* use facts
* use well written articles that provide true value
Use social bookmarking buttons on the newsletters publishing pages, so people can bookmark them. This increases the backlinks and traffic to your site. Keep the newsletter subscription form on these newsletter archives pages.
