Microsoft Outlook

Microsoft Outlook has been the gold standard for email for a while, and for a good reason. It provides many features, and its integration with the rest of Microsoft’s stack makes it a fantastic productivity tool. The critical turning point was when Microsoft adopted other platforms. It was vital to release it from “windows only” systems. Outlook benefited a lot from being released into macOS, for example, iOS and Android. People started adopting it as their email client of choice, even for their private emails.
