Examples include a welcome email sent as soon as a new client signs up to your list of contacts, followed a few days later by an informatory email discussing the products and services you offer, then an email informing on current offers, and so on. You could also create different series of post-purchase emails, based on the type of product the individual purchased.
I use Ratepoint because they also offer a review (testimonial) widget I have posted on my site. Ratepoint has a promotion that offers free mailing list service forever if your list is 125 or less. Obviously most of us will want more than 125 folks reading our newsletters but it’s a good start. Good templates, tracking and definitely awesome support.

AWeber is an easy-to-use email marketing tool that allows business owners and entrepreneurs to cultivate relationships with their customers. Since 1998, AWeber has been the email engine powering the growth of organizations around the world, including leading sites like Social Media Examiner and ProBlogger and industry influencers such as Peter Shankman and Ann Handley.
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.
I am not signing up for an account so I don't know exactly how the API works, but if I were setting up an iPhone App to work with this, I would use the rails plugin. Rails gives you JSON communication for free (IE no extra work required) http://guides.rubyonrails.org/layouts_and_rendering.html see section 2.2.9. Then use on IOS app use something like: http://code.google.com/p/json-framework/ to interact with that.
And that was that. I didn’t really get any help afterwards, but I trusted that most of them were getting through because my broadcasts were being replied to, and I just hoped it was just some bug or internal error and not actually brakes being put on my emails. I was again, appreciative of the quick call to attention, but was still left hanging a little.

I love press releases as a tool to drive tons of traffic to my sites fast. In addition by including keywords you can get ranked for topics and answers that your audience finds of value. The key is to write in a newsworthy style and not like a sales letter or advertisement. You need to have something of value if you want to get non-paid organic media attention.
If Objective-C isn't your thing, their is Titanium from Appcelerator, you use JavaScript to build your app and it gets compiled into Objective-C. Mobile Tuts has a nice tutorial on how to consume the Twitter API, which is also REST based. It should give you a good foundation to get you started.

Title. Creating a title is the single most important thing you should focus on. Over time, you should get as creative as possible and test various types of email titles. It is the first thing a user sees, and it should be created to engage the reader and make them open the email. The more engaging your email subject is, the higher the open rates are going to be.

Migration can actually be a major pain in the ass. Although according to aWeber my list was “substantially clean” but I still needed to get all my readers to reconfirm their subscriptions. After a week I’m still waiting for 70% of them to reconfirm. NOT happy. If I stuck to mailchimp I wouldn’t have had these problems. (Their support guys are good though.)
So, when a new person signs up to your site (via your newly created signup box), they will (after confirming their subscription) start to receive the set of emails that you have setup.  You can create as many as you want and schedule them to be sent out at different intervals (i.e. 1 a day, 1 a week, 1 a day and then another one in a month’s time, etc.).

Email #2, sent to subscribers a day later, pitched my eBook study guide. I had explained that it was everything they needed to know to pass the LEED exam, conveniently packaged into a printable PDF file and delivered immediately upon purchase. The link in the email sent people over to my sales page, which had a lot more information on the features and benefits of the product.
The whole idea of email marketing may seem intimidating to you – it certainly did to me. I’ve gone through several different methods of engaging with my email list, and have only recently settled on something that I’m really comfortable with (general ranting).

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.
