Every time you send out an email without a link below your e-mail signature, you are missing a valuable opportunity to drive traffic, and therefore to boost sales, as an affiliate. Whether the e-mail is being sent to an e-zine mailing list, a select group of subscribers, or specific individuals, there is always a relevant opportunity that you can mention. When linking, use a redirect file so that the link promotes your web address as well. This simple add-on technique does not require any additional work; it simply helps to ensure that, as part of your affiliate efforts, you are optimizing the effectiveness of the message you are already sending.
