Spark

Notifications, subscriptions and important mail pile up in the inbox, and handling mail as a team is awkward. Spark is smart and collaborative: an email client with a smart inbox and team collaboration, surface important mail automatically, let teams compose and discuss mail together, unify multiple accounts, and sync Mac and iOS, handling mail fast and tidily. A macOS app.
