The most interesting feature of Spark Mail is smart email sorting that keeps important mail on the front and unnecessary or spams at bay. It is simple yet elegant and quite user friendly, not only in the app but also in the browser version too. Not so popular Spark Mail is one of the best alternatives for Apple Mail as it provides a smooth experience and supports cross-platform. One can try the below-mentioned third-party apps with advantages and disadvantages. However, one such thing that is common between all stock apps and the third-party app is that they want to look simple for user friendly. The latter one is especially important because often email comes with large attachments that encroach upon major space in the cloud. Most of the time, users and clients emphasize customization, visually soothing, cloud management, and cloud-free space. Apple does not take security for granted, but no major update has put the app in a vulnerable position. Some users look for better integration with other apps, while some seek a lag-free experience and better security.
