The story of Ubivox
The first virtual steps towards our newsletter service were already taken back in 2003, when we released the first version. Back then, the system was called eBrev (Danish for eLetter) and its capacity and speed was considerably less than what we can boast about today.
After a couple of complete rewrites and a lot of experiences gained, the current incarnation of Ubivox is a solid piece of software that we are very proud of.
Below is a short timeline that shows how the Ubivox system has evolved throughout its life until now. We've only included major feature releases.
