deepthi sDo you know that over 130,000 phishing emails are being sent throughout the world as you read this sentence?
Because of the rise of AI-powered attacks, phishing has increased by 1,265% in just the last year.
Take your inbox as an example. How many suspicious emails have you received this week alone?
Your email is now the gateway to your entire digital infrastructure, from cloud storage and financial systems to customer databases and proprietary information. In this blog, we’ll discover why email security matters more than ever and explore the best practices for securing email accounts that top organisations are implementing today.

Why Email Security Matters
Here are 5 facts that prove why email security should be a top priority:
- Phishing is still the top cybersecurity threat.
- More than 90% of cyberattacks begin with a single email.
- Business Email Compromise (BEC) scams rob businesses of billions every year.
- The AI-generated phishing makes malicious emails look 99% legitimate.
- A single hacked account can result in a string of breaches through various departments.
- Regulatory fines (e.g., under GDPR, HIPAA, and so on) for data breaches can be devastating to smaller companies.
The challenge is that email threats are constantly growing. Old security measures that used to work five years ago can no longer protect you. Attackers now use social engineering tricks, generate AI-generated content, and use modern techniques to bypass basic filters.
They know about your organisation more than you; they know how to craft personalised messages to your employees and strike when you’re most vulnerable.

Core Email Security Best Practices
The following are some of the email account security tips every organisation should use.
Strong password policies
If you use any of such passwords like “Password123”, “Birthdate”, and “12345”, or repeat the same password for various accounts. Then, stop doing this right away.
Follow these practices to form a strong password:
| Password Element | Best Practice | Example |
|---|---|---|
| Length | Use phrases instead of words | “Coffee-Drives-My-Morning-Code!23” |
| Complexity | Mix of uppercase, lowercase, numbers, symbols | “Coff33&Cod3@Morning!” |
| Uniqueness | Different passwords for each account | Use a password manager to track them |
| Regular Updates | Change every 90 days for sensitive accounts | Set calendar reminders |
| Avoid Common Patterns | No dictionary words, personal info, or sequential characters | Avoid using “Admin2024” or “Company@123” |
Multi-Factor Authentication (MFA)
If you choose to apply just a single security measure from this whole guide, then let it be this one. Multi-factor authentication is such a powerful protection that it becomes literally impossible for attackers to get into your account by simply using your password.
As stated by Microsoft, MFA prevents more than 99.9% of account takeover attacks.

Email Encryption
Sending a regular email is similar to sending a postcard. Here, email encryption is like placing that postcard in a locked box that only the intended recipient can open. This is an important email security practice.
Many email security solutions, including those offered by Mitigata, provide built-in encryption capabilities that are easy to deploy and manage.
Regular Security Awareness Training
Around 96% of successful cyberattacks involve some form of human error. You can include some of these topics in your cybersecurity training for employees:
- Phishing and Social Engineering
- Password Security and Authentication
- Safe Email and Browsing Practices
- Incident Reporting and Response
- Data Privacy and Regulatory Compliance
- Deepfakes, AI Manipulation, and Voice Spoofing
- Cloud and Collaboration Tool Security
- Ransomware and Malware Defence
- Insider Threats and Data Handling

Email Filtering and Anti-Spam Solutions
Advanced email filtering solutions use artificial intelligence and machine learning to:
- Block known phishing domains and suspicious senders
- Scan attachments for malware
- Identify spoofed emails that appear to come from trusted sources
- Filter out spam that clutters inboxes and hides real threats
- Quarantine suspicious emails for review before they reach users
Regular Backup and Recovery Plans
Many companies discover the importance of backups only after losing data. Regular email backups can be helpful in retrieving deleted emails and meeting data retention requirements.
Implement SPF, DKIM, and DMARC
SPF, DKIM, and DMARC are the digital ID cards for your emails. They make sure that your domain’s messages are real and not spoofed by cybercriminals.
If they’re properly configured, then they can prevent others from sending fake emails that appear to come from your company. A substantial reduction in phishing and brand impersonation risks can be anticipated as a result of this measure.
Every day, around 3.4 billion phishing emails are sent. Learn about these types of phishing emails and stay ahead of such scams.
How to Protect Your Email from Being Hacked
Commonly used attack methods can easily be countered with the following measures:
Spotting Phishing Attempts
- Shady Sender Address: The email is supposedly sent from your bank, however, the address is “support@yourbank-secure.net” which is not a bank using the official domain. Always check the sender’s name and email address before taking any action.
- Use of Urgent or Threatening Language: “Your account will be suspended in 24 hours!” or “Immediate action is required!” are some of the best examples of popular phishing methods.
- Use of Generic Greetings: “Dear Customer” as opposed to your actual name. Phishing emails are often broadcasted to thousands of people and thus, the emails usually contain a generic greeting that might be misleading.
- Shady URLs: Prior to clicking on any link, make it a habit to check it carefully. In case the link text shows “www.microsoft.com” while the URL is “www.micros0ft-login.com“, you should be very alert.
Not Just Any Email Security
Partnered with top-tier providers to deliver custom-fit email security at the best price.
Dealing with Suspicious Emails
- Don’t click anything: Even the smallest doubt should not force you to click on links or open attachments; you should rather stay away from doing that.
- No Response: By replying you give confirmation that your email address is active which in turn makes you an even bigger target for the next attacks.
- Change Passwords If Required: In case you inadvertently opened a web address or gave some information, change your passwords right away and inform the IT security department as well.
How to Make Your Email More Secure
The following are some advanced strategies that can be used to improve the security of your email:
Use Encrypted Connections (TLS/SSL): Make sure that your email provider always uses HTTPS, so that mails are encrypted during transfer.
Login Alerts Setup: Alerts should be activated to inform users about logins from unknown places or new devices.
User Roles Segmentation: Admin access should be restricted and least-privilege principles applied.
DLP (Data Loss Prevention) Activation: Prevent the sending of sensitive data via email unintentionally.
Changing Recovery Options Regularly: Keep your phone numbers and backup emails updated.
Don’t Use Public Wi-Fi: Avoid using public Wi-Fi for accessing or sending sensitive emails. In case of having to connect, use a Virtual Private Network (VPN).
MDM Solutions Installation: A Mobile Device Management solution should be used for security policies enforcement and lost devices remote wiping.
Context-Based Access Limitation: Implement access control based on context which recognises factors such as user location, device type, and IP reputation before allowing access.
Domain-Based Message Authentication Implementation: Legit senders can be authenticated and fraudulent messages blocked by setting up SPF, DKIM, and DMARC.
| Password Element | Best Practice | Example |
|---|---|---|
| Length | Use at least 12–16 characters | correcthorsebatterystaple |
| Complexity | Include letters, numbers, and symbols | P@ssw0rd!2024 |
| Uniqueness | Use a different password for every account | One password per platform |
