Definitions: opt-in, double opt-in, and opt-out
Here’s what each term means within a legal email marketing strategy:
- Opt-in: the user gives consent by checking a box before receiving marketing emails.
- Double opt-in: after giving consent, the user confirms a second time via a validation email. It’s the most secure method.
- Opt-out: the user is subscribed by default and must unsubscribe if they don’t want to receive emails.
These methods may seem similar, but they have a major impact on compliance, brand perception, and the quality of your email list. To learn more about these terms and 50 other email marketing terms you need to know, check out our email glossary.
