return receipt

we released our corporate newsletter today strictly for clients and "strong" leads/prospects.
some e-mails have return receipts confirming the delivery of the message.
one return receipt from a client's e-mail made me smile wide. hehehe..
the message goes like this..

"This is a Return Receipt for the mail that you sent to gdfgfdgdfg@&^%$.com.

Note: This Return Receipt only acknowledges that the message was displayed on the recipient’s computer. There is no guarantee that the recipient has read or understood the message contents."

and why would a return receipt include a note like this -> "..There is no guarantee that the recipient has....understood the message contents.""

haha! :p
i found that a bit funny.
