DejaLu for Mac Icon
Here's a replacement icon I created the new up-and-coming Mac email client called DejaLu (from ex-Sparrow developer Hoa V. DINH):
The icon was inspired by one of DejaLu's new features called "Zen Notifications". The idea is to show a notification only when you haven't seen an email come in. Instead of showing every unread count, it is a much more gentle reminder that is less intrusive to work and life.
The icon idea came from the idea of something minimalistic and zen-like. I created the blue gradient from the blue of DejaLu's message list unread dot and the DejaLu branding light blue.
Hope you enjoy!
