Mobile email is on the verge of mass adoption, and based on the assumption that between 35% and 40% of these inboxes could potentially be mobilized, Datamonitor believes the addressable market for enterprise mobile email is around 260 million subscriptions.
There are some 650 million corporate email inboxes worldwide. According to the latest industry figures on mobilized email accounts, the number of subscribers currently stands between 5 and 6 million, indicating that the mobile email market is still in its infancy, and promising strong growth for many years to come.
According to Datamonitor surveys, 50% of the European enterprises interviewed have already deployed mobile email solutions, while mobile Personal Information Management, which bundles mobile email, messaging, calendar, address book, notes, bookmarks, and remote file access, lagged behind slightly with 34% of respondents saying they had already deployed a mobile PIM solution.
This is a notable increase on results of a comparable survey conducted a year ago when mobile email penetration was at 39% and mobile PIM penetration was at 28%. Another interesting trend in the survey was an even steeper increase in the number of respondents saying they plan to deploy mobile email and mobile PIM over the next 12 months.
The survey revealed that mobile PIM is catching up with mobile email. Mobile email penetration grew by 11 percentage points between 2004 and 2005. In the same period, mobile PIM penetration grew by 6 percentage points.
