You’ve sent out an important email, and a couple days later, you still haven’t received a response. Was your message read and ignored, or forgotten; or was it buried in a full Inbox, never even opened? Wonder no more! You can now request read receipts in Gmail, thanks to Boomerang's new Read Receipt and Click Tracking features.
Once you install Boomerang, just click the Request Read Receipt and Track Clicks icon in the bottom right of the Gmail compose window. Boomerang will add a read receipt notification to the bottom of the message, and will also track clicks on any links you have included in the body of the message. Soon after the message is read, Boomerang will send you a notification that the recipient has read your message.
You can easily view additional information about your tracked messages by going to your Boomerang Manage page. Click on the Boomerang link in the black bar at the top of your Gmail window, then choose “Manage Scheduled Messages” from the drop down menu. Under the "Tracked Messages" tab you can see more details including how many times your message has been read, or which links have been clicked.
