I limit my email to once per month, and I have the coupons valid all month. I know nothing about website creation or HTML, but I can fill in the email form, upload my photos and play with the look. Then I hit “send,” and all 1,667 customers receive my specials in their inboxes.

Sounds to me she might be “cannibalizing” her sales a little, but the strategy is sound:

1) You have a real world business
2) Offer a prize worth $200-$500
3) All they need do is fill in a form including email address
4) Tell them you intend to send them vouchers!
5) Send them vouchers sometimes
6) Do anything else that web marketers do - you have an audience!
