Most will e-mail you if there are shops in your area. Most will allow you to set the radius in your profile somewhere. Some think 20 miles is in your area, some think 60.
Some will e-mail you if they have shops in your state claiming they are near you. Others seem to send you e-mails if you live in the same country as the shop.
Also, Sassie seems to deactivate the e-mail flag which you can find by looking in the upper left of the main screen. Fix it in your profile page if it is turned off. I don't know how to stop this, perhaps someone else will know.
