It's good for sending emails with attachments easily via mobile devices without worrying about data loss or virus attacks. I don't like how you can only do one email at time so sometimes it takes some effort just because there are too many options available in this app which make me confused from what should i choose first. This helps us send information quickly over text messaging (SMS) as well as through e-mail when we have difficulty using our desktop computers due to being away from them while visiting patients' homes.
