Freedom to Geek Out
Thunderbird is yours.
Thunderbird is clean and elegant by default, but easily customizable to match your workflow and visual preferences. It is loaded with unique and powerful features. Here are just a few that people love:
Its unified inbox enables me to stay sane even in the busiest of times. I am never switching e-mail clients again!

I love the tag feature. I tag something important and find it quickly.

It is the first program I install on any PC I use / own... I use it on Windows / Mac and Linux.

Having an open source alternative [for] receiving and managing email... is great for privacy.

[Thunderbird] empowers me to maintain ownership of my emails.

You'd be hard pressed to find a client more extensible than Thunderbird!
