Here are some examples:
- If you're doing a new product launch email, you may want to at least break out your prospects vs. your existing customers.
- If you're sending out a email newsletter, break out a list between those who have subscribed to your newsletter vs. those that are part of a list that you may have purchased. You can even dig down deeper to break out the list between those that have signed up say in the last 2 months vs. the rest of the newsletter subscription group. Get creative!
Bloggers sending out their own email newsletters are becoming extremely popular. Problogger and Blog Traffic Kingare just two examples of very successful email blog newsletters (we need a better name for these - how about "blogletters" or "b-newsletter" ?). As your blog newsletter increases in popularity, don't forget to measure the key metrics that made you so popular. In addition, if you're looking at targeting some new key prospects, try experimenting with your lists as suggested above.
