I do this too:) I've aliased this to the keyword "sendmail" in chrome by adding it as a search engine in preferences, so I can just type "sendmail" or "sendmail email@example.com" in the url bar.
However, an even higher win for me is aliasing search in the same way. I used to find that when I went into my email to look for a particular piece of info I would get so distracted by my inbox that I never ended up completing the task I was originally working on. I've aliased https://mail.google.com/mail/u/0/?shva=1#search/<searcht...; to "ms <searchterm>", such that I can type "ms paypal" in my url bar and get all my recent paypal receipts without having to be tempted by my inbox first:)
My only frustration is that gmail is still so damn slow to load. I know they've spent a lot of time trying to make this fast (I spent about 2 years working on reducing latency on Google search), but they're still so far away from where they could be.
I really, really wish gmail loaded the html first, showing my inbox or search or whatever, and then loaded and attached all the javascript later. This could result in search level latencies for the initial load of data for the user to start looking at, even if it took a while longer to be fully interactive.
