Top 8 Email Security Best Practices for 2025

Strong passwords are the first line of defence in email security solutions for employees. Here are some guidelines for securing your email with a strong password:

• Use at least 18 characters or more as it is better to have longer passwords. .
• Combine uppercase, and lowercase letters, numbers, and symbols for maximum complexity.
• Don’t use personal information like birthdays or pet names, and avoid the use of dictionary words.
• Create unique passwords for each account. Resist the temptation to reuse the same password across different platforms.
• An example of a strong password is aPpl3ar3n0tmyfaVor!t3. The password is easy for your to remember but difficult for others to guess.

Two-factor authentication (2FA) adds a powerful extra layer of security to your email protection. It goes beyond just your password, requiring a second verification step whenever you log in to your account. This makes it significantly harder for unauthorised users to access your email, even if they manage to steal your password.

To enable 2FA for your email account, Log in to your email account settings. And go to the security section. Find the option for two-factor authentication or multi-factor authentication and choose your preferred verification method, such as receiving a code via text message, using an authentication app, or a security key. Follow the on-screen instructions to complete the setup process.

Below are the steps for to configuring 2FA with Google Authenticator:

• After installing the authenticator app, Set up app under Authenticator app.
• Open the Google Authenticator app on your phone.
  You’ll see a barcode on your computer screen. Scan the barcode using the Google Authenticator app on your phone.
• Alternatively, you can enter a secret key displayed on your computer screen into the Google Authenticator app.
• The Google Authenticator app will generate a unique 6-digit code that changes every 30 seconds. Enter this code in the field provided on your computer screen.
• Click Next. You might be prompted to choose a backup method for your 2FA in case you lose your phone. Follow the on-screen instructions to complete the setup.

Educating your employees on email security best practices is a fundamental step in protecting your organization. However, building and maintaining an internal IT security training program can be resource-intensive. This is where partnering with a managed IT Service Provider can be incredibly beneficial.

Managed IT Service Providers are staffed with cybersecurity experts who are constantly updated on the latest threats and email security best practices for employees. With their expertise, you can ensure your employees receive comprehensive email security training without the burden of developing and delivering the program yourself. This training empowers your employees to identify email Security – key defense against business cyber risks, and become active participants in reducing cybersecurity risks.

A good antivirus solution with managed email security features is a critical safeguard for your email marketing efforts. These solutions go beyond basic virus protection, offering a comprehensive protection against a variety of email-borne threats. Some of the best viruses for email security include Norton, Bitdefender and Total AV. Here’s how these antivirus software protects your email from malware:

• Real-time Scanning: The software continuously monitors incoming and outgoing emails, scanning for malicious attachments, links, and content in real-time. This provides a vital first line of defense, preventing threats from reaching your inbox.
• Attachment Analysis: Antivirus software with other email security best practices dives deeper, analyzing the files attached to emails. This helps identify suspicious attachments containing malware or other harmful code before they can infect your system.
• Phishing Detection: Phishing scams are a common tactic used by cybercriminals to steal sensitive information. Secure email solution features can analyze the content of emails, identifying red flags associated with phishing attempts, such as suspicious sender addresses, urgency tactics, and misleading links.
• Behavior Monitoring: Some antivirus solutions go beyond simply identifying known threats. They employ behavior monitoring to detect suspicious activities associated with malware, even if it’s not yet flagged in the antivirus database. This proactive approach helps to stop zero-day attacks and other emerging threats.

By combining antivirus solutions with other email safety tips, you can significantly reduce the risk of threats and safeguard your valuable customer data.

Equipping your employees with the knowledge to recognize and avoid email threats is crucial for a good email security strategy. Below are some ways that you can implement for effective email security training for employees:

• Have Policies that Keep Sensitive Data Safe: Establish clear guidelines on handling sensitive customer data within emails and educate employees on data classification and appropriate sharing practices.
• Teach Employees About Cyber Threats: Inform them about common email scams like phishing and spear phishing and explain how to identify suspicious emails and attachments. Also make them familiar with the emerging Cybersecurity trends to keep them updated with the current things.
• Require backup of all important data: Emphasize the importance of regularly backing up critical information to ensure data recovery in case of a cyberattack or accidental deletion.
• Have regular security checks: Schedule regular security awareness training sessions to keep employees updated on evolving threats. Also, encourage open communication where employees can report suspicious emails without fear of reprisal.

When it comes to email security guidelines, ensuring your email communication travels through encrypted channels is very important. This is where Transport Layer Security (TLS) comes in. TLS is a cryptographic protocol that establishes a secure connection between your email client (like your web browser) and the email server. With TLS enabled, all communication – including the content of your emails, attachments, and sender/recipient information is encrypted before being sent over the internet. This encryption scrambles the data, making it unreadable to anyone who might intercept it.

Here’s how TLS secures your email communication:

• Client Initiates Connection: When you send an email, your email client initiates a connection with the email server.
• TLS Handshake: A secure “handshake” is established between the client and server, where encryption keys are exchanged.
• Data Encryption: Both parties use the agreed-upon encryption keys to scramble the data being transmitted.
• Decryption at Destination: Only the intended recipient has the decryption key to unlock the scrambled data and read your email.

Developing a culture of caution around email links is one of the best practices for email security. Here are some key points that you should look into:

• Is the Link Legitimate: Don’t automatically trust links, even if they appear to come from familiar senders. Hover over the link to preview the actual URL before clicking.
• Sense of Urgency: Phishing emails often try to pressure you into clicking a link by creating a sense of urgency. Be aware of emails demanding immediate action or threatening consequences for inaction.
• Verify Sender Identity: Double-check the sender’s email address as cybercriminals can spoof legitimate email addresses to trick you.
• Don’t Download Unknown Attachments: Unless you’re expecting an attachment from a trusted source, avoid downloading unknown files as mail attachments can be a common way for malware to infiltrate your system.
• Report Suspicious Emails: If you receive a suspicious email, don’t just delete it. Report it to your IT department or the email service provider to help them identify and address potential threats.

By encouraging employees to think critically before clicking on links or opening attachments, you can significantly reduce the risk of falling victim to email-borne threats and strengthen your overall email security practices

Keeping your email password confidential is essential in email security best practices. Sharing your password results in loss of control of your account, allowing unauthorized access to sensitive information, the ability to send malicious emails under your identity, and even complete account takeovers. Furthermore, sharing your password increases the overall security risk, as a compromise of another person’s account could expose your login credentials as well. Remember, email service providers offer secure collaboration methods like shared folders and access permissions. Utilize these features instead of resorting to password sharing to safeguard your email security.
