✅ The 7-Point Inspection — How to Tell if an Email is Fake
Below is a simple yet powerful checklist anyone can use when analyzing a suspicious message.
1. Inspect the Sender’s Email Address Carefully
Don’t trust the display name—the real sender is hidden in the email address. Watch for:
- Impersonation using generic domains
support@paypal.com@gmail.com 🚩
- Slight domain manipulations
amaz0n.co → fake
rnicrosoft.com (rn instead of m) → fake
Tip: Hover over the sender or tap for details on mobile to reveal the full email origin.
2. Watch for Unusual Tone or Language
Professional organizations use consistent formatting and clean grammar. Red flags include:
- Emotionally charged language (“account suspended”, “final warning”)
- Strange tone shifts—too formal or overly casual
- Slight grammatical errors typical of AI-generated scams
3. Hover Before You Click Any Links
Links are phishing traps 🪤. Before clicking, hover (desktop) or long press (mobile) to preview:
- Mismatched domain links
https://paypal.com → OK
https://paypa1-security.com/login → ❌ Fake
- Suspicious redirects or tracking URLs

4. Treat Attachments as Dangerous by Default
Malware is often disguised as invoices or resumes:
- .exe, .js, .scr, .zip attachments → Dangerous
- Unrequested documents (e.g. “Invoice #4598”) → Be cautious
5. Beware of Generic Greetings
Fake emails often start with plain greetings:
- “Dear Customer,”
- “Dear User,”
- “To Whom It May Concern”
Real companies usually address you by name.
6. Never Share Personal Information via Email
Legitimate organizations never ask for:
- Passwords 🔑
- Bank PINs 💳
- Scans of IDs or passports 🛂
7. Check Branding Details
Even if the sender uses real logos, scammers often miss:
- Consistent branding or colors
- Proper alignment and formatting
- Updated logos or legal footer text
