While Alice sends email to Bob (by using usual email client software like Microsoft Outlook Express, Eudora, Pegasus, The Bat! or similar), Email Spy invisibly captures and sends exact copy of Alice's email to your secret email address as well. Actually you will receive Alice's email copy almost simultaneously with Bob.

You have used "Don't send emails to real recipient" program option. Now while Alice sends email to Bob, Email Spy invisibly captures and sends exact copy of Alice's email to your secret email address ONLY. Bob will not receive Alice's email at all if you will not decide to resend Alice's email to him (after your review of course).
