Zimbra (acquired by Telligent) Review

Although the look and feel may be pretty slick and give you lots of flexibility in creating widget and manipulating the inside pages, this platform offers a little or almost not existent support in all that is community management related. First of all, it doesn't send automatic email digests (unless you fight for them); second, it doesn't allow to see list of members and to measure engagement in a personalized manner; third, there is no customer support and their internal links keep changing so you have no access to documents that explain the features; forth, it doesn't work on mobile. We used it for over two years and they did not provided any product enhancements. We are now finally transitioning to Higherlogic.
