What is required for a method to "opt-out" of receiving emails per the CAN-SPAM Act?

For a method to "opt-out" of receiving emails as per the CAN-SPAM Act, it must be clear and easy to use. This requirement is in place to ensure that recipients can easily express their preference to stop receiving marketing emails. The law emphasizes that the opt-out mechanism should be straightforward so that consumers are not burdened with complicated processes or unclear instructions when they wish to unsubscribe. This consumer-friendly approach helps protect individuals' rights to control the communications they receive.

Other methods, like those requiring a paid service, sending messages as text, or demanding verification of identity, do not align with the intent of the CAN-SPAM Act, which aims to prioritize user convenience and clarity in the opt-out process.
