Gmail Notifr is an app (or website) that helps users stay on top of their Gmail inbox and quickly respond to important emails. It notifies users when they receive emails, and allows them to view the emails, reply to emails, or archive emails right from the notification. The app also provides users with customizable settings so they can decide which emails they want to receive notifications for, and how they want to receive those notifications (via sound, a badge, or an alert). Gmail Notifr is a great tool for busy professionals who want to stay on top of their emails and respond quickly.
