Phishing attacks are getting more sophisticated, but you can protect yourself by learning to spot the red flags in fake emails. Below are practical, easy‑to‑follow steps that anyone can use to verify an email’s legitimacy.

What are the warning signs of a fake email?

Look for mismatched sender names, urgent language, and unexpected attachments. Phishers often use spelling errors or slightly altered logos to create a sense of legitimacy. If the email asks for personal data or login credentials, treat it as suspicious. Unexpected links that don’t match the claimed domain are a major red flag. Always hover over links to see the true URL before clicking.

How can I verify the sender’s domain?

Start by checking the email address’s domain part – the text after the @ sign. A quick Google search can reveal whether the organization uses that domain for official communications. Government agencies, banks, and large enterprises typically use their own corporate domain, not generic services like Gmail or Yahoo. If the domain looks unfamiliar, search for “domain name + official website” to confirm its legitimacy. You can also use Palisade’s Domain Checker to see if the domain passes authentication.

Why should I avoid official‑looking emails from free email providers?

Legitimate organizations rarely send official correspondence from free services such as Gmail, Outlook, or ProtonMail. Those providers are meant for personal use and lack the branding that a corporate domain provides. If you receive an “official” notice from a free address, it’s a strong indication of spoofing. Attackers exploit the trust you might have in the message content, not the sending address. Always expect a corporate domain for business‑related communications.

How do I check email authentication results in Gmail?

Open the email in Gmail and click “More” → “Show original.” The original message view displays SPF, DKIM, and DMARC results at the top. A “pass” status for all three indicates the email is likely authentic. If any of these show “fail” or are missing, treat the message with caution. For a deeper dive, use Palisade’s DKIM checker or SPF validator.

What does it mean if SPF, DKIM, or DMARC fail?

A failure means the email did not originate from an authorized server for that domain. SPF verifies the sending IP, DKIM confirms the message wasn’t altered, and DMARC ties the two together. When any of these checks fail, the message is likely forged or sent from a compromised account. Attackers can still spoof a domain that lacks proper authentication. Consider the email unsafe and report it to your IT or security team.

Can a legitimate email still be compromised?

Yes – even if SPF, DKIM, and DMARC pass, a hacker may have taken over a valid account. Compromised accounts can send authenticated messages that appear trustworthy. Look for unusual requests or content that doesn’t fit the sender’s normal style. When in doubt, verify the request through a separate channel, such as a phone call. Monitoring tools can alert you to sudden spikes in outbound email from a single account.

What are look‑alike domains and why are they dangerous?

Look‑alike (or “cousin”) domains are variations of a legitimate domain, often with a misspelled word or different TLD. Attackers register these domains to trick users into thinking the email is genuine. Because they can set up proper SPF/DKIM/DMARC, the authentication checks may pass. Always double‑check the exact spelling of the domain in the From address. If you spot a subtle change, treat the email as suspicious.

How can I confirm an email’s legitimacy through another channel?

Reach out to the sender using a known phone number or a separate email address you’ve used before. Do not reply directly to the suspicious email, as that could confirm your address to attackers. Verify the request’s details, especially if it involves financial transactions or sensitive data. Many organizations have dedicated security or IT help desks for phishing verification. A quick call can save you from a costly breach.

What steps should I take to protect my own email domain?

Implement DMARC with a “reject” or “quarantine” policy to block unauthorized senders. Publish strong SPF records that list only your authorized mail servers. Sign all outbound mail with DKIM using a robust key length. Regularly monitor your domain’s authentication reports for anomalies. Palisade Monitor provides real‑time visibility into who is sending on your behalf.

Frequently Asked Questions

Is it safe to click links from a free‑email address?

No. Legitimate businesses rarely use free providers for official communications. Treat any request for personal data from such addresses as suspicious and verify through another method.

Can I rely solely on DMARC to stop phishing?

DMARC is essential but not a silver bullet. Combine it with user education, endpoint protection, and continuous monitoring for the best defense.

How often should I review my domain’s authentication records?

Check at least quarterly, or after any major email system change. Automated alerts from Palisade Monitor can notify you of sudden failures.

What if my organization uses multiple subdomains?

Publish consistent SPF, DKIM, and DMARC records for each subdomain, or use a wildcard DMARC policy that covers all of them. Palisade can scan all subdomains in one view.

Do I need technical expertise to set up these protections?

Palisade’s tools are designed for both technical and non‑technical users. The step‑by‑step guides walk you through record creation, and support is available if you get stuck.
