I use Gmail for all of my email addresses – even my school ones forward to my Gmail account. It is amazingly simple to manage a large volume of email, and it keeps getting better.
If you are not yet familiar with the Google Labs options available from within Gmail, you’ve got to check them out.
I’ve got keyboard shortcuts enabled, signature tweaks, canned responses, and many other tweaks setup through the Google Labs features. Now, when I get to my inbox with 30 or 50 emails – I can whip right through them, usually without even using the mouse.
Recently added, Google Search right within Gmail, whether you’re composing an email or not. This is extremely useful if you’re trying to find a link or some information for the email you’re writing – I can’t tell you how many times I’ve had to open a new tab or window, do my Google search, and then cut and paste the URL. Now – all in one little window. Genius!
