Promote up-sells/cross-sells. You can even set up an autoresponder sequence for someone after they purchase and get repeat customers. Depending on the products you sell, you could offer an upsell, or cross-sell related products. For example, if someone buys a digital camera, you can offer to add a lens, a tripod, and other accessories to their order before it ships. Or, if you sell products that people buy frequently (like food or disposable items, like diapers), you can automatically send them offers for new items when you know they’re about due for another order.
The usability of most of the site is actually not bad; I even like the design look and feel. However, the signup process is where I had (and am still having) trouble with. Just simply getting a reply from them on anything takes hours and hours, but when you look search usability and mailchimp.com, they are all kinds of busy writing blogs about their mobile usability testing and how great they are. So they are so focused on their mobile they forgot that the #1 focus should be getting new users fast, and keeping them with good support… what a JOKE! Mailchimp.com is usability and customer support FAIL!
Have you ever wondered if it’s possible for an email automation tool to integrate with other applications such as Salesforce or Shopify? Emma Mail does it for you! This platform also offers subject line split testing using Google analytics and real-time metrics reports. In addition, you also get to personalize emails, say when a contact just made purchase, or hasn’t opened past emails you’ve sent.
Note: it needs to be said that Aweber has *just* rolled out a new beta upgrade called Campaigns which I would assume, aims to do some of these features. I received my invite just as I was making the switch to ConvertKit, so I haven’t tried it. It may do the trick. That said, some of the other features I dislike about Aweber are still relevant, so regardless of this new feature, I’m staying put with ConvertKit.
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.
