I feel honored to be a member of an industry that collaborates and shares in such a holistic and kind way. This project is focused on supporting that community. Each resource listed here was created by individuals who decided to share their knowledge and skills instead of hoarding them. Thank you all!
This collection continues to grow thanks to the submissions from fellow email geeks. There are so many amazing resources out there and I don't know most of them. You all make this list something worth sharing.
