Although Gmail is the world’s leading web email service measured by the number of unique visitors worldwide, it doesn’t dominate any one region of the world. Data from ComScore shows Gmail (s goog) and Yahoo Mail (s yhoo) to be competing over similar markets, including North America and Asia Pacific. Yahoo, for now, is in the lead in those regions.

Hotmail (s msft), boasts a more unique market with a significant lead in Latin America, Europe and Middle East-Africa. We graphed Yahoo, Google and Hotmail’s top-five markets — in terms of the percentage of online users in each country who use the service — to show how each stacks up in their respective regions.

Drag the map around to see how the services stack up in other parts of the world.
