Shtyle.fm - and the Teddy

[Reverend]

A friend of mine is unwittingly sending an attachment with his outgoing emails.

It says 'Chris has sent you a Teddy.' It's some kind of greeting message that claims you've won a gift. (see attached)

There's a link to 'opt out' of Shtyle emails at the bottom but I don't want to recommend that he clicks it, it's only going to confirm his address.

Anyone know how to get rid of it?

Thanks - rev
