Spark email app

Spark is an email client developed by Readdle, a Ukrainian company founded in 2007. The app was introduced in 2015 and has since expanded to multiple platforms, including iOS, macOS, Android, and Windows. Spark is designed to enhance email productivity by offering features such as smart inbox organization, collaborative email drafting, and integration with various email services. In 2017, Readdle hired Terry Blanchard, former Apple Mail engineering manager, to lead the development of Spark, aiming to reinvent the email experience.
