WhoReadMe can go beyond tracking what happens to your emails. It can also tell you the recipient’s IP Number, their browser and also their location on the map. This will all be invisible to the recipient. To use WhoReadMe you sign up on the website, click on an activation email and then you can send any emails you want tracked via the website, but your usual email address will be given to the recipient. There is a limit on the number of emails you can track per day, but they can have a number of CCs on them.
