I have this question about e-mail merge (no spam) for a client. He want's to send 2.000 mails to his clients. Why, he organises a Musical and want some of the music incorporated in this mail. He wants the music to play for 30 seconds when the people read his mail.

Can I integrate a sound that starts automaticly when the e-mail is opened? If yes, how can I achieve this?

Thanx to you all willing to help me!
