Ring's mailbox sensor tells you if you've obtained mail
While we can use tracking numbers to keep track of our deliveries, this doesn't always apply to things like letters. If you want to keep up to date with new emails in your mailbox, check out Ring's new mailbox sensor, the name of which is actually pretty simple and meaningful.
The ring mailbox sensor can be attached to your mailbox outside of your home. Whenever the mailbox door is opened, you will receive a notification letting you know that you may have received emails. This is useful when you're trying to keep an eye out for a specific letter you're expecting, or just emails in general.
However, it can also come in handy if you think someone is checking your email because when you are at home or have a security camera, you can check that the mailbox door is open that it is by an authorized person like being opened to a postal worker or when one of your nosy neighbors checks in at your place.
The Ring Mailbox Sensor itself costs $ 30. But if you don't have the bridge you need, you can put this together for $ 50.
