Looks like Hotmail is actually growing, while Yahoo is down. What this doesn’t tell you is that Gmail gained 22% over the last year, while Hotmail only gained 3%.
As mail traffic at Yahoo has dropped an average of 11% in 2010 versus last year, the fall in its overall U.S. traffic has averaged 8%. Yahoo Mail remains top in total email page views in the U.S., but Microsoft‘s Hotmail and Google’s Gmail are grabbing share. Internationally, Hotmail has the most page views, and is building its lead according to comScore.
