Having to wait for your mail carrier all day long when you expect an important package is not fun. Thanks to Postybell, you don’t have to. It is a sensor that you put inside your mailbox to get alerted when mail is delivered. The sensor sends you an alert when you have a mail and works from any distance. The device does have a proximity sensor and a GSM model. It is compatible with smartphones and regular ones.
Postybell will have an Android app. An iOS version will be available in the future. You can monitor multiple mailboxes with this. The device sends you real-time alerts. It also tells you when the battery is running low. You can even forward alerts to an alternative phone when you are traveling. This cool product is on Indiegogo.
