A very cool and inexpensive software tool has made my life easier for quite some time. MSGTAG works with Outlook and allows you to see exactly when someone opens your email – without use of return receipts (I use MSGTAG+ at $19.95). FYI, it doesn’t work with Hotmail, Yahoo, AOL, or any protocol that requires SSL (like Gmail).
Any other silent stalker software apps like MSGTAG that you like?
