A recent survey on email archiving commissioned by GFI Software, based on 202 US-based SMEs, found that a growing number of organizations are considering or would consider a third-party hosted email archiving service. A total of 18% of those organizations that already use an email archiving solution, have opted for a hosted service, while 38% said are open to using such a service.

At the same time, 51% of those surveyed said they would still only use an on-premise email archiving solution.

The findings paint an interesting picture of email archiving use among SMEs. Apart from the shocking statistic that more than 63% do not archive their email, those that do, or consider doing so, are interested in the various options available.
