Find out if your emails were read. Simply install and any future emails are automatically tracked. A circle will appear when the tracking is enabled on the sent email and a checkmark will appear when it has been read. Works for unlimited email accounts and sent emails.
Email tracker does not ever store or transfer your email contents in order to ensure your privacy.
Emails sent to only yourself are not tracked. If you want to test the extension send an email to another email account.
