If you’re not familiar with Informed Delivery by the U.S. Postal Service, it’s a free service the post office offers to let you know what you’ve got coming to your mailbox. You’ll get a digital image of the letters you’ll be receiving that day directly to your email address. It also informs you about packages sent via US Postal Service.

You’re being urged to sign up for this free service before a scammer does. According to the security website krebsonsecurity.com – last month, the Secret Service reportedly sent an internal alert to its law enforcement partners warning them of a scam where criminals would sign up for other people’s mailboxes and then steal credit cards from those people’s mailboxes.

Sign up for Informed Delivery right here: InformedDelivery.usps.com

You can also, reportedly opt your address out of the service entirely by emailing [email protected].
