Double Opt-in

A technique used in opt-in or permission based marketing. It ensures that a potential customer actually wants to receive the marketing materials and is a way to prevent unwanted spam. The basic process is as follows:

• A potential customer requests information from a website and is asked to confirm that they want the information to come to their e-mail address.
• The potential customer then receives a confirmation e-mail in their inbox. This e-mail requires them to click on a verification link to receive further information.
• Once the potential customer receives verification, they will receive the future messages from the mailing list, e-course or autoresponder series.

Services such as Aweber provide double opt-in mailing list capabilities.
