Email Marketing
Opt-In
An opt-in is the process by which a user gives explicit consent to receive marketing communications from a brand. It is a fundamental requirement for email marketing compliance and building a permission-based audience.
Examples
A website uses a double opt-in process where subscribers confirm their email address by clicking a verification link before being added to the list.
Best Practices
Use clear, honest opt-in language, offer a compelling incentive, and implement double opt-in to ensure list quality and compliance.
