Double Opt-In
The term “double opt-in” typically refers to a second action confirming permission has been granted by the recipient to receive emails. This can be done through a confirmation email or through a web page. The confirmation email asks recipients to either return the email or click a hyperlink to confirm the recipient’s desire to receive this information. Marketers who feel the definition of opt-in should already include the second action of signing up for the email message may not use the term “double opt-in” because of its perceived redundancy.
