We participate in what’s called permission marketing, signifying that the recipients of your emails have given permission to be contacted. The purpose for this is two-fold: first, hostile recipients rarely make willing customers. There’s no practical use in sending unsolicited emails, because your click-thru rate will suffer. Second, email marketers with a complaint rate greater than 0.1% will be blocked by most ISP’s, meaning your future emails will not be delivered. Emails should be anticipated, personal, and relevant. If yours are not, you’ll want to reevaluate your pupose in sending them in the first place.
