I have seven e-mail accounts synced to my BlackBerry, and I'm always getting e-mails from random companies that have my address(es) on distribution lists. Obviously, e-mail is the primary communications tool for the industry that I work in, so I have to check my device regularly during the work day. There's nothing more irritating than when I'm expecting an e-mail from a colleague, only to find out that it's Chemistry.com (don't ask, it was a family joke earlier in the year) reminding me that my membership is (yet again) about to expire.
For those with similar issues, Elertify could be the best tool since sliced bread. A PC-based software program, it alerts you of calls, e-mails, and text messages in an attempt to reduce the number of times you check your device throughout the day. What's more, the software has the capability to translate the phone call/message for you. Elertify is designed for those that work closely to their computers, as it requires the USB cable to be connected for the program to work properly.
Elertify works on BlackBerry OS 4.2.1 or greater, and requires Windows 7, Vista, or XP. BlackBerry Desktop Manager must be installed. Regularly $5.99, it can be had for $4.99 until November 15th. If I had a PC (or if I had a dual boot solution), I would try it myself. For those that do purchase it, let me know what you think!
