In prepping my review of the new Hotmail over the past week, I started noticing that there were a lot of interesting numbers being tossed around in the meetings I had with Microsoft and in the materials they provided. So I created a simple document to collect them. Here they are:
370 million active Hotmail users worldwide
About 75 percent of Hotmail users--or over 275 million users--also use Messenger
350 million Office documents pass through Hotmail every month
Over 15 billion Office documents are stored in Hotmail right now
1.5 billion photos are delivered through Hotmail every month
New photo and Office document sharing limits in the new Hotmail: 10 GB of photos or documents per email message, up to 200 photos/documents, each up to 50 MB in size
Exchange ActiveSync compatibility is available on roughly 300 million phones worldwide
80 percent of mail reported as "spam" is not spam but is instead "junk mail" or "gray mail"
50 percent of the typical email inbox is unwanted mail of some kind (spam or junk mail)
Almost 90 percent of all web mail traffic online is spam
Today, only 4 percent of mail in an average Hotmail inbox is spam, down from 35 percent in 2006 (Using Gmail metrics, it's just 1 percent)
Getting rid of spam is email users' number one feature request. Number two is the inability to send large attachments. Number three: Junk mail and clutter reduction
Every user gets unlimited storage capacity in the new Hotmail
