Works well, relatively easy to use - but lacks some up-to-date and modern features as well as look and feel. The support provided is OK but not world class. It is too bad as APSIS as a company is quite good at inspiring and providing insights into trends in email marketing.
The user interface is not good. Too much scrolling and too many menues to navigate. Half of the pages are updated to a "new" look with the rest still being the (really) old design. This badly needs a make-over.
There is no one-click "send reminder to those who did not open". To send reminders, it is nescessary to build a filter a do a new send using the filter. Such a simple and often repeated task should be automated.
It is not possible to add a "Why did you leave us?"-page for opt-outs... Really misses this.
The statistics are too limited and to difficult to use - mostly due to the UI design as described above.
MailChimp offers more flexibilty but also seems a bit more complicated to use. We did not use it long enough to really get an idea of the positive and negative.
We are still trying to figure out how to use this medium for sales. We have had some success with Black Monday sales, but in general we do not have much response to our emails.
We have increases our visibility with our customers by making sure to land in their mailbox regulary with nice looking messages.
