It has a solid API which helped us implement some automations in our work processes without too much effort. Review collected by and hosted on G2.com.
Limit of user amount in a distribution groups - this forces us to create new distribution groups. Since we also rotate a lot of people we then remove them from the older groups which results in empty space and it's very clunky to try and change the group ids in our code all the time. I also don't like that a user page doesn't have any information which groups is the user member of. Review collected by and hosted on G2.com.
