Opt-In and Opt-In email

Opt-in is where the users gives consent to receive communications or emails from an owner of a list or a website. Opt-in usually describes a process in which the user gives consent. The strategy of building a process that allows users to opt-in is always good business because its simply more effective for advertisers. This is because users have agreed to  receive targeted communications. Its even better for web site owners and list owners to employ a double Opt-in. This approach gets the user to further confirm their interest in receiving communications through an extra request e.g to respond to a verifying email.
