This is a really good post. I have been thinking about thi slately. I basically have the same info in my newsletter, but i have been getting lots of new sign ups and want to make over my newsletter. I think it has a lot to do with who you have your letter through. I use bravenet as its free and I think adding a special offer every month just for newsletter recipeints got me more readers, ppl actually have been reading to find out what sale i have for them. Also when i do contest. I think most ppl look for a bright and inviting letter to read and make sure you start it with something thats gonna grab the attention. A catchy title helps too. Hopefully other will give some good suggestions.
