Even though someone else might have sent you an e-card, the "From" line in the email message you receive lists your email address. Since we don't collect the email address of the sender, we can't pass that along to you. We put your email address in the "From" line of the email in case you try to reply to the message you were sent. Replying to the email only sends a message to yourself, not to the sender or to Yahoo! Kids E-cards.
To see who sent you the card, read the body of the email message—it gives you the name the sender typed in when they sent you the card.
To send an email or e-card back to the person who sent your a Yahoo! Kids E-card, you need to know the sender's email address.
