Thunderbird

Like its foxy-browser sibling, Thunderbird takes top spot again this year in the e-mail category. Now that Canonical has adopted Thunderbird as its default e-mail client in Ubuntu, we see the popularity rising for our blue-birdie friend. Still hanging on tightly to second place is Gmail. Is Gmail an app? We're not sure, but it certainly does get votes as the best e-mail client. Because Thunderbird can access Gmail servers easily, it's possible this category blurs the line a bit, as users simply can use both. When it comes to picking a favorite though, Thunderbird is the clear victor with more than twice as many votes as our runner-up.
