Many marketers advertise and simply give a Web site address, no e-mail contact.
When a person is reading their e-mail, they may not have their browser open and they don't want to get distracted from their reading. Answer - put an autoresponder address in your ad. They click the email link and when they finish reading their ezine they will have the information they were after waiting in their email box. Also if you only provide a URL, they may only look at your site for a few seconds. They will never be followed up on.
