Set it and forget it for years.
The most-reviewed mailbox sensor, with a base station that connects to Wi-Fi.
Three kinds of alerts so nobody misses the mail.
A Tuya sensor that shares alerts with the whole family.
The longest range here, for long driveways.
A cheap app-alert mailbox sensor.
A small sensor inside the mailbox detects the door opening or motion and sends an alert to your phone. Metal mailboxes block radio signals, so most use long-range radio with an indoor hub or receiver.
Check the stated range. Long-range models reach a quarter mile or more; Wi-Fi models need Wi-Fi coverage at the curb.
Most do. The hub plugs in indoors and passes alerts to the app.
