How well do you understand email security? Let’s put your knowledge to the test.
- What should you do if you get an email from an unknown sender with a link?
A) Click it to see what it is
B) Forward the link to a colleague
C) Avoid clicking the link and report it instead - Which of these is a sign that an email might be a phishing attempt?
A) It greets you by name
B) It comes from your coworker’s email address
C) It has spelling mistakes and urgent language
That means you’ve got a solid handle on the email security basics. But let’s be real: protecting your inbox goes way beyond avoiding shady links and setting a strong password.
Every day, the world sends around 347 billion emails, and a good chunk of them aren’t exactly friendly. About 45% are spam, 26% are phishing attempts, and 2.5% carry malware just waiting for someone to click.
While the fundamentals like strong passwords, spam filters, and a healthy dose of skepticism still matter, email remains one of the biggest weak spots for businesses.
So, if companies are spending big on email security tools, why do major threats still sneak through? The problem isn’t always the tools themselves—it’s how they’re used or misused.
Let’s dig into 10 best practices that can help you get more out of your email security setup and actually keep the bad stuff out of your inbox.
10 Best Practices to Enhance Your Email Security Solutions
Enforce MFA on Email Platforms
Multi-Factor Authentication (MFA) adds a smart extra layer of security when logging into your email. After you punch in your password, the system asks for a second piece of proof that you’re really you. This could be a time-sensitive code sent to your phone or a physical security key. By requiring something you actually have, it makes it a lot tougher for anyone to sneak in— even if they’ve got your password.
Customize Advanced Threat Protection
Businesses need Advanced Threat Protection (ATP) to tackle the email threats that go beyond basic spam. ATP adds an extra layer of analysis to catch malicious attachments, dangerous URLs, and zero-day exploits that might slip through standard filters.
While just deploying an ATP solution is a good start, the real power comes from customizing it to fit your company’s unique threats and risk tolerance. And don’t forget—regularly reviewing and tweaking the settings keeps you one step ahead of evolving dangers.
Optimize Email Filtering and Anti-Malware
While not a catch-all for advanced attacks, strong email filtering and anti-malware are still essential pillars of email security. Good filtering keeps spam and malicious emails from cluttering your employees’ inboxes, while updated anti-malware can catch known threats before they lead to data breaches or system compromise.
To get the most out of it, make sure your email system’s spam filter is set up properly and that anti-malware is always up to date. Regularly check how well your filters are performing and tweak the settings as needed.
Deploy Email Encryption Policies
When it comes to protecting sensitive information, email encryption is a must. It scrambles your data so only the right people can read it—whether the email is on its way or sitting in an inbox.
To keep things locked down, always encrypt emails containing sensitive data. You can use Transport Layer Security (TLS) to protect emails in transit, and S/MIME or PGP for end-to-end security. Don’t forget to securely manage your encryption keys—store them safely and control who can access them to prevent unauthorized decryption.
Implement Outbound Email DLP
Outbound Email Data Loss Prevention (DLP) helps keep sensitive information, like customer lists or financial details, where it belongs, stopping it from leaving your organization via email.
To make the most of DLP, set up solutions that scan outgoing emails and attachments for patterns of sensitive data. Then, create policies to either block, quarantine, or warn users about potentially risky email transmissions.

Conduct an Email Security Training
When a seemingly legitimate email asks for sensitive information or demands urgent action, the difference between a secure business and a vulnerable one often comes down to its employees.
More businesses are investing in employee training, and for good reason—it’s proven to help prevent phishing attacks. According to the Verizon Data Breach Investigations Report, the rate at which users report phishing emails is on the rise, even when they haven’t clicked a malicious link.
To stay ahead of threats, make sure your team is regularly updated with comprehensive email security awareness training. Cover key topics like identifying phishing attempts, practicing safe email habits, and knowing how to report suspicious activity.
It’s also important to remember that attackers thrive on emotions like fear and urgency to trick employees into clicking links or downloading malicious files. So, the next time you check your inbox, keep an eye out for signs like:
- Impersonal greetings (e.g., “Dear Customer”)
- Requests for login details or unusual transactions
- Minor errors in sender emails or website addresses
Utilize Email Authentication Protocols
Email authentication protocols are crucial for verifying that the sender of an email is who they say they are, helping to prevent domain spoofing—a common tactic in phishing attacks.
To safeguard your domain, implement SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance). Don’t forget to regularly review DMARC reports to keep tabs on email senders and spot any spoofing attempts before they cause harm.
Implement Email Archiving Solutions
Beyond basic storage, dedicated email archiving provides a secure way to store all your email communications in a searchable format. This is not only crucial for legal discovery and compliance but also a lifesaver when investigating security incidents.
To make the most of it, implement a robust email archiving solution that captures and stores email data in a way that fits your business needs. And don’t forget—ensure the archive is both secure and easy for authorized staff to search when needed.
Integrate Threat Intelligence Feeds
To stay ahead of emerging email threats, it’s essential to tap into external information about known attackers, their tactics, and the clues they leave behind. Threat intelligence feeds provide this crucial context.
To make the most of it, connect your email security tools—like firewalls and gateways—to trusted sources of threat data. Set them up to automatically block or flag emails linked to known threats, so you’re always one step ahead.
Develop Email Incident Response Plans
Even with strong email security in place, issues can still arise. That’s why having a clear plan for what to do when things go wrong is crucial. Practicing that plan ensures your business can bounce back quickly and minimize any damage.
To make sure you’re prepared, create a detailed email security incident plan. This should outline who’s responsible for what, how communication will flow, and the exact steps to take to stop the issue, eliminate it, and return to normal operations. Don’t forget to regularly review and test your plan to keep it up to date.
