Spam & Blacklist

Definition

Email phishing is a type of cyber attack where criminals send fraudulent emails that appear to come from trusted sources to trick recipients into revealing sensitive information. These deceptive messages often mimic legitimate organizations like banks, social media platforms, or employers to steal login credentials, financial data, or personal information. Phishing attacks can also deliver malware through malicious links or attachments that infect the recipient's device.

Common Phishing Scenarios

Fake password reset emails from banks or social media platforms

Invoice or payment requests impersonating vendors

CEO fraud targeting employees with urgent wire transfer requests

Package delivery notifications with tracking links

Account verification emails claiming suspicious activity

Tax refund or government benefit scams

Job offer emails requesting personal information

Tech support scams claiming device infections

Why Email Phishing Matters

Email phishing poses significant risks to both individuals and organizations. For email marketers, phishing undermines trust in email as a communication channel, making recipients more suspicious of legitimate messages. Understanding phishing helps you design emails that don't trigger spam filters or appear suspicious to recipients. It also emphasizes the importance of proper email authentication (SPF, DKIM, DMARC) to protect your domain from being spoofed in phishing campaigns targeting your customers.

How Email Phishing Works

Email phishing typically begins with attackers researching their targets and crafting messages that appear legitimate. They use social engineering techniques like urgency, fear, or authority to pressure recipients into acting quickly without thinking. Common tactics include spoofing sender addresses to look like trusted contacts, creating fake login pages that capture credentials, and embedding malicious links disguised as legitimate URLs. Attackers may also use attachments containing malware or direct victims to compromised websites that exploit browser vulnerabilities.

Best Practices to Prevent Phishing

Implement SPF, DKIM, and DMARC authentication on your domain

Train employees to recognize phishing indicators like urgency and suspicious URLs

Verify requests for sensitive information through separate communication channels

Enable multi-factor authentication on all critical accounts

Use email filtering solutions that scan for phishing indicators

Hover over links before clicking to verify the actual destination URL

Report suspected phishing emails to your IT security team

Keep software and security tools updated to patch vulnerabilities

Frequently Asked Questions

What are the warning signs of a phishing email?

Common phishing indicators include generic greetings instead of your name, urgent language pressuring immediate action, suspicious sender addresses that don't match the claimed organization, spelling and grammar errors, requests for sensitive information, and mismatched or shortened URLs that hide the true destination.

What should I do if I clicked a phishing link?

Immediately disconnect from the internet to prevent data transmission. Change passwords for any accounts you entered credentials for. Run a full antivirus scan on your device. Monitor your accounts for unauthorized activity and consider enabling fraud alerts. Report the incident to your IT department and the organization being impersonated.

How does phishing affect email deliverability?

Phishing indirectly harms email deliverability by making recipients and email providers more cautious. If your domain lacks proper authentication, your emails may be flagged as suspicious. Implementing SPF, DKIM, and DMARC proves your emails are legitimate and protects your sender reputation from being damaged by spoofers.

What is spear phishing vs regular phishing?

Regular phishing casts a wide net with generic messages sent to thousands of recipients. Spear phishing targets specific individuals or organizations with personalized messages based on researched information. Spear phishing is more dangerous because the tailored content makes it harder to detect as fraudulent.
