Opt-in Rate

Opt-in rate refers to the percentage of people who choose to participate in a service, mailing list, or offer after being given the opportunity. For example, if 100 people see an invitation to subscribe to a newsletter and 25 decide to sign up, the opt-in rate is 25%. It’s a key metric for understanding how effectively your message encourages interest and engagement from your audience. A higher opt-in rate generally indicates that your offering resonates well and motivates people to actively choose to be involved.
