Newsletters are a great way to communicate and share ideas about your products and services and do a bit of soft selling as well. A newsletter has several distinct advantages over a blog and the most important is that you are not committed to the harried pace of continually updating your blog.  You set the pace of release – once a month, once a quarter. It doesn’t really matter, so long as your content is effective.

The real trick is building a broad mailing list that successfully covers your field of interest.
