HEY is a premium email service launched by 37signals in June 2020. [1] [2] [3] [4]
The service may be accessed through the HEY website and through apps for macOS, Windows, Linux, Android and iOS. [5] [6] Due to the service's vertical integration, a HEY mailbox cannot be incorporated into other email services or stand-alone email clients. [7]
Around the time of HEY's launch, a stand-off between Basecamp and Apple Inc. over Apple's policy on in-app purchases in apps hosted by its App Store was the cause of significant media attention upon Apple's policies. [8] [9] [10] [11]
