I am just beginning to use Runbox 7. I signed up for a year. When the year was up, I signed up for the three year plan. I already have at least 5 email addresses. They become quite burdensome with advertisement and data mining. So I am investing in runbox which still has a long way to go, but what I see is promising. The exclusion of advertisements is fantastic. So keep improving, runbox, and I’ll join up for another three years.
