They clearly don't understand how to create teaching materials; they are confusing and vague at best. Both the videos and the written material are very poorly designed. Probably the worst aspect of Mailchimp and the reason why many of my colleagues have been evaluating other Autoresponders.
On a scale of 1-10 its usability rating is 1 because there are so many things going on behind the simple easy-to-use interface that are hidden and difficult to find and change. Anything to do with the forms is very poorly designed and not so intuitive.
The link between campaigns, lists and automation is confusing and doesn't make sense. Why does the campaign dropdown even exist? If it's a broadcast email why not use some simple language. It seems to me that simplicity is not a concept they've come across as yet. Except for their user interface but then it hides the complexity and difficulty of using the software.
Its system of writing emails is very clunky. On one side you write the email and on the other side the text appears. It is the only email autoresponder that does this. It is well behind the competition in this regard
Creating sub-segments is a nightmare when you want to creat a short introductory course and move people into another segment
When sending out emails you only have the option to send out emails within a certain time range. Even when you're testing your own emails it can take up to 20 mins to receive your test email.
The sending aspect of the autoresponder is unreliable. I"ve received emails at all sorts of times. You cannot predict within one hour when emails are to be sent out. As a power user of AR you need your emails to go out at a precise time not when it suits mailchimp.
If you are considering using mailchimp the question you should ask is how simple is it to use. The effectiveness and usefulness of the training material leaves a lot to be desired. On this basis alone it is a terrible mail service.
