Opt-in vs. Opt-out

Opt-in and opt-out are terms used to describe how individuals give consent to receive information or participate in activities. **Opt-in** means you actively choose to join or receive information, like signing up for a newsletter. Your permission is required before any communication starts. **Opt-out**, on the other hand, means you're automatically included unless you specifically request to be removed, such as being added to a mailing list without prior consent. You have to take action to stop receiving information. These approaches affect how companies engage with their audiences and how privacy is maintained.
