Implementing opt-in and opt-out mechanisms involves:
Clear Sign-Up Forms: Ensure that your sign-up forms clearly state what users are signing up for, including the type of content and frequency of emails. Confirmation Emails: For double opt-in, send a confirmation email with a clear call-to-action for the user to confirm their subscription. Unsubscribe Links: Include an easy-to-find and straightforward unsubscribe link in all your emails.
