This e-mail is your first contact with an online advertiser to request that the advertiser take you off his e-mail list.
I have received your e-mail advertising consistently for the past <timeframe>, and it has become enough of an annoyance that I must e-mail you and request that you remove me from your mailing list. I am a busy person and receive a great deal of business-related e-mail, and the extra messages that you generate do little more than clutter my In Box. Please stop sending me your e-mail advertisements. I appreciate your attention and quick action in this matter. Thank you.
