If you struggle to keep up with the emails flowing in to your device throughout the day, SmrtAlerts may help you out. The award winning app gives you a popup alert when a new email arrives, allowing you to preview the message no matter which application you are using. You get details on the sender and a brief clip of the message, and can easily open the full email or delete it right away. SmrtAlerts lets you configure a filter for which apps to be notified in, and features a spam blocker to whitelist/blacklist messages and senders. SmrtAlerts regularly sells for $9.99, but you can grab it today for just $4.99 in the CrackBerry App Store. Hit the link below for more info.
