Sparrow is an email client platform originally designed for Mac and iOS (iPhone OS) systems, and later, it was devised for Windows systems as well. Soon after the first arrival, Sparrow was acquired by Google, and further development of this platform was discontinued. Thus, the platform has never received any upgrades since then. If we talk about the GUI, it does not include any fancy interface that may lure to use it. A user can go through the threads of communication without facing any technical issues. To view the concerned email, just select it and have a preview in a new window pane. On the other hand, if the user has multiple email accounts, they can be accessed through the multiple accounts switching feature.

However, with more use of advanced platforms like MS Outlook, Sparrow users are also migrating to Outlook at a fast pace. Moreover, Outlook has always been keeping high standards in terms of security and features, gaining recommendations all over the globe. Users willing to migrate files from Sparrow mailbox to Outlook require assistance from an external utility such as Kernel for MBOX to PST.
