This software alerts you when your friend reads that email you sent.

Our company brought the MSGTAG Status for approximately less than RM 228.00 (USD 59.95) at a discounted price during New Year Promotion. Definitely a must for corporate users who want to know if their emails are received by their clients / superiors.

Another interesting theory is that, for those who are pak-thoing (cantonese for dating), this software is a MUST.
