MSGTAG Free (Message Tag) is a nifty little freebie that ensures you always know when your emails have been received and viewed.

It is compatible with almost all desktop email clients, including Outlook Express, Mozilla Mail, Thunderbird, Incredimail, Eudora and Pegasus Mail.

A tiny icon sits in your system tray, from where you can activate and deactivate the MSGTAG tagging.

Activate tagging and MSGTAG will send you a confirmation email whenever an email is received. It informs you when the email was sent, when it was viewed and the elapsed time in between.

At no time is your privacy violated, and the confirmation email is sent automatically, with no intervention required from the recipient.
