What You’ll Miss in K-9 Mail

When it comes to navigating e-mails, K-9 Mail allows users to enjoy limited gesture-based controls. Templates for emails can neither be created nor saved in this e-mail app. There is no Rich Text support. This is quite a let-down, considering that it offers customization of the entire mailbox but no formatting tools for the emails! Overall, this app has its reasons for coming into the limelight every now and then. It is definitely a vast improvement over the default email client offered by Android on your device. Also, if something is a shortcoming, users will offer feedback and development teams will use these inputs to continuously enhance the app.
