Spam Filter

A simple tool to make sure that any important e-mail that from a sender you have not previously whitelisted will be hidden from sight, while most of the emails that still make it to your inbox will still be spam. A device that saves no one any time if you want to catch all of your important mail from non-white listed senders, because you still have to manually search through all of the spam to check for the important e-mails within. If the post office implemented a similar spam filter, your tax refunds and stimulus checks would not be delivered and unless you went in person to the post office to check through your spam, it would be put into the shredder after 30 days.
