Thunderbird Lets You Fly Through Your Email
Mail clients have lost their luster in recent times. Between social media fulfilling the messaging needs of many people and webmail's growing popularity, desktop email apps are beginning to look passé. Still, email clients have their adherents. I count myself among them. I like the idea of having all my email on my computer, not in someone's cloud where someone I don't know might peruse it.
