WhoReadMe is an online platform which provides free email tracking service since year 2007. Email tracking is a method for monitoring the status of email delivery on a recipient. The sender receives a read receipt when email is opened.
There are two ways to send tracked email. You can login to your WhoReadMe account and send email using this Website. Alternatively, you can send tracked email from your favorite email clients such as Microsoft Outlook, Thunderbird, Eudora, etc... All you need is adding a suffix .whoreadme.com to your recipient email address. For example, if you want to send an email to email@example.com, the recipient address will be firstname.lastname@example.org. You do not need to install any additional software.
WhoReadMe is using a very simple concept to track emails. WhoReadMe inserts an invisible tracking image into emails you sent. Once the image inside the email is loaded from WhoReadMe server, the server will send out a notification to inform you.
