When I first started blogging several years ago, I jumped onto the aweber band wagon. I built a subscriber list of over 400 people. I was posting regular articles and then a monthly newsletter with more in-depth articles for free. I was spending so much time writing, I never created a product and the onsite ad’s were not bringing in enough money to cover the cost.
Personally, product creation is something I've always enjoyed. Still, it can be hard at times to come up with ideas for new products that are unique, or have a unique twist to them. Even an experienced and creative individual can learn a lot from this video series. I know I did. I especially appreciated the lessons on product pricing, how to get testimonials, and creating multimedia packages. Not to forget the sources for ideas, which are priceless! Once again you've knocked it out of the ballpark with this one! Thanks! - Karen Denning

The problem is that your list is so big (both long and we were working with a lot of columns and a few equations) that Excel on my computer couldn’t handle it. I have a ton of memory on my computer, but it wasn’t sufficient. For example, when I tried a simple task like sorting the list, it would take several minutes to process the operation. I would literally click ‘Sort’ and then go and work on another task for a while.
With so many new things to contend with and trying to grasp the bigger picture, it is easy to forget that ..er, the newsletter (of some kind) has to be set up. So my “complaint” was that there was no reminder nor alert that I might want to set up a newsletter. A very useful and needful reminder/alert for a newbie! But one does not turn to Customer Support for that!
Creating separate lists allows you to segment your subscribers. So, for example, I would never send a message to subscribers on my IE Publishing the same messages I send to those on the Get a Mobile Career. Different group of folk. Those on the IE Publishing publishing list are interested in my fiction (mostly romance novellas); not in affiliate marketing. Here’s an explanation for each box on this page.
I actually use both services today so I can keep this review up to date. Overall, I think Aweber has a better deliverability rate which is a huge reason to use them. Furthermore, i like the way they do autoresponders much better than MC. On the flip side, MC has a much easier to use API if you are into coding and manipulating your lists programmatically.
I have used both, and I agree with your analysis. The great thing about MailChimp is that it lets you see the email in different clients. That is really the hardest thing about sending emails. However, you can use that service without doing everything else through MailChimp. Also, once you get the hang of it and develop templates, it no longer is much of an issue.

Think about implementing referral links to incentivize your subscribers to spread awareness about your brand, too. Referral links allow your current customers to promote trackable links for your business. In exchange for sending new paying customers your way, you can give them incentives like discounts, coupons, vouchers, cash, prizes or redeemable points.
