Thunderbird is excellent. I tried it for a while, and it's great. But the lack of native features like Schedule Send, Snooze, and Translate, not available as add-ons, makes me quit and look for other email client options. The add-ons for these features are ugly, poorly crafted in their interface and appearance, and they don't fit in with the interface and appearance of the email client. Please finally make these options an integral part of Thunderbird's email client.
