What is Confirmed Opt-In?
Confirmed opt-in, also known as double opt-in, is a process where a subscriber confirms their subscription to an 
email list through a secondary action, typically by clicking a confirmation link sent to their email address. This method ensures that the provided email address is valid and that the subscriber genuinely wants to receive communications from the sender.
    A user enters their email address into a subscription form on your website.
    The system sends a confirmation email to the provided address, which includes a unique link.
    The user must click the confirmation link to verify their subscription.
    Upon clicking, the user is added to your email list and receives a welcome message or further instructions.
