Opt-in list

An opt-in list is a collection of contacts who have voluntarily agreed to receive communications from a business or organization, typically via email or other messaging channels. This consent ensures that recipients are interested in the content or offers they receive, helping organizations build trusting relationships and comply with privacy regulations. People usually opt-in by signing up through a form or subscription process. Maintaining an opt-in list is important for effective marketing, as it targets engaged audiences and reduces the risk of being marked as spam.
