On Message with Ben Gross

The market research firm Radicati Group issued some new figures this week about the messaging market that are quite interesting. Radicati reports that “there are about 668 million email users worldwide, with over 1.2 billion active email accounts. Worldwide email traffic per day totals about 135 billion messages, of which 67% are spam.” Overall, “Spam traffic totaled 91 billion messages per day in 2005, and this figure is expected to reach 228 billion messages per day by 2009.”

In the ongoing race between Exchange and Notes, Radicati says that “Microsoft maintained its lead over IBM Lotus in 2005 – MS Exchange has 23 million more seats than Lotus Domino.”

Radicati also predicted strong growth in archiving and wireless markets, noting “The email archiving market is expected to double in size annually over the next four years, and revenue in the wireless e-mail market is expected to increase by over 300% by 2009.”

The IM and messaging management markets will grow more slowly. “Revenue in the Instant Messaging market will increase at an average annual rate of 27% over the next four years. In the messaging software market, revenue will increase at a steady average annual rate of 9% between 2005 and 2009,” Radicati said.
