Single Opt-in: a process where users give permission to receive email from a specific entity by performing a single step such as filling out a subscription form on a web site or a subscription sheet at a trade show explicitly granting permission to be emailed.

Double Opt-in/Closed Loop Opt-in: a process where users give permission to receive email from a specific entity by performing two steps: an initial subscription step followed by a confirmation step.
