An app that will be integrated with your email system- email read alert! How often do you encounter the situation- you keep waiting eagerly for a reply and wonder whether the recipient of your email has even read it or not? I'm sure very often.
This app will send a notification to sender once recipient(s) opens the email. If you feel your email will take at least 5 minutes to read properly you can set additional option of notifying you the time interval for which the email is kept open. So no need to keep on refreshing your mailbox for a reply! You'll know once your email has been opened.
Alarm for those who tend to delete emails before even opening them!!
