This is a good example of a poorly designed software product. The product is slow to learn new languages, but even worse, does not provide any sort of tutorial. Even worse still, once the application has been installed, there is no documentation on how to use the product! We spent hours trying to figure out how to do something as basic as import contacts. We contacted support and the only response we received was to refer us to a blog post. After reading the blog post, we were able to find a forum where we could ask our own question and received an answer from another user. In addition to this, there is no ability to add a custom domain (e.g. [email protected]). And the worst part of it all, the whole process is extremely cumbersome and takes forever! It took me 2 days to configure the product.
