I like that they have a free version which allows me to test it out before purchasing. The support team is very knowledgeable about their product and can help walk me through any issues or questions I may be having. They also do a wonderful job making sure everything looks great in both desktop and mobile devices. There are several features I use daily such as my profile page, notifications, etc but there isn't one feature in particular that I dislike. Their customer service has been excellent so far. It would still be nice if all plans had more than 5 users per plan. Also, we wish that certain paid features could be used with free accounts. For example, our entire business relies heavily on push notifications and email marketing campaigns. In order to keep up with demand, we need to constantly update these messages and send them to many different people/em.
