About this app

Protect yourself and your family from scams before they strike. MailShield Guardian uses advanced AI to analyze suspicious mail, texts, emails, phone calls, and QR codes — giving you a verdict in seconds.

SCAN PHYSICAL MAIL
Point your camera at any letter, postcard, or package. Our AI reads it and instantly flags sweepstakes scams, fake government notices, prize mailers, and more.

CHECK TEXTS & EMAILS
Paste any suspicious message and get an instant risk assessment. Catch phishing links, impersonation scams, fake package alerts, and bank fraud attempts before you click.

VERIFY PHONE CALLS
Enter a phone number or describe who called. MailShield checks it against known scam patterns and our community database — and automatically labels future calls from flagged numbers.

SCAN QR CODES
Never get redirected to a malicious site again. Scan any QR code to preview the destination URL and get a safety rating before you tap.

CHECK BEFORE YOU PAY
Someone asking you to send money? Describe the request and let MailShield assess whether it's legitimate or a scam — before you transfer a single dollar.

FAMILY DASHBOARD
Set up protection for aging parents or family members. Receive real-time alerts when they scan something risky, so you can step in immediately.

COMMUNITY SCAM INTELLIGENCE
Every flagged scam is anonymously shared across our network. The more people use MailShield, the smarter it gets — protecting everyone from emerging threats.

HOME SCREEN WIDGET
See your household's threat summary at a glance right from your home screen. Know instantly if anyone in your family has encountered a scam.

MailShield Guardian is built for seniors, families, and anyone who wants peace of mind in a world full of scams. Simple, clear, and always watching out for you.
AI scam protection: mail, texts, calls, QR codes & payments. Guard your family.
