Spam Filters Catch a Lot. They Don't Explain Why.
Mail P.I. gives you a second opinion before you click — no app to install, no IT ticket to file.
Forward the Email
Something feel off? Send it to check@mailpi.app from any device, any email client. First time, confirm your email with one click — after that, just forward and go. You get 5 free scans a day.
We Investigate the Email
We check sender reputation, authentication, links, domains, and writing patterns for common phishing techniques — twice, so one analysis keeps the other honest.
Get Your Answer
A risk score from 0–100, a plain-English breakdown of what we found, and clear guidance on what to do next.
What Mail P.I. Looks For
The best phishing emails don't look suspicious. Mail P.I. is built to catch the subtle stuff that spam filters miss — especially in small business inboxes.
Clear Risk Score (0–100)
Every email gets a score, so you know how concerned to be at a glance.
Sender Domain Age
A domain registered last month sending a "business proposal" today? That's a major red flag — and Mail P.I. catches it automatically.
Link & Domain Analysis
Checks every URL for suspicious redirects, lookalike domains, and malicious destinations hiding behind legitimate-looking text.
Plain-English Explanations
Not a security report full of jargon — a clear explanation of what's suspicious and why, written for real people.
Attachment Scanning
Attachment types and filenames are assessed for malware delivery tactics and credential harvesting attempts.
Ready Whenever You Need It
No IT person on call? Forward anytime — nights, weekends, holidays — and get a report back, usually within about 30 seconds.
Built for Small Businesses Without an IT Department
That moment of "is this email real?" is exactly what scammers count on. Mail P.I. gives every employee a fast, private answer — no ticket, no embarrassment.
Small Business Owners
Protect your team from phishing without hiring an IT department or installing anything.
Sales Teams
Spot fake order scams and lookalike domains before they cost you a deal — or a wire transfer.
Office Staff
Get a private second opinion without bothering the boss or filing an IT ticket.
Solopreneurs
One wrong click can cost thousands. A 10-second check before you act is all it takes.
Your Email Is Analyzed — Not Stored
When you forward an email to Mail P.I., it's analyzed and gone. We never store your email content — not temporarily, not in logs, not anywhere. Only anonymized, hashed metadata is retained to manage usage limits.
You're getting a second opinion, not handing over your inbox. Privacy isn't a feature we added — it's how the system was built from day one.
