Email Security Best Practices

Email Security Best Practices

Your email is one of your most important and most targeted accounts — it is the key to your other accounts, holds sensitive information, and is the main channel for phishing. Following email security best practices protects not just your inbox but your entire digital life. This guide brings together the essential email security practices in one place, in plain terms.

Secure Your Email Account Strongly

Given email's importance, secure it as a priority:

• Use a strong, unique password: Your email password should be strong and used nowhere else, since email is critical and a breach elsewhere should not compromise it. A password manager helps.
• Enable strong 2FA: Enable 2FA on your email, ideally with an authenticator app or security key rather than SMS (vulnerable to SIM swapping). This is one of the most important protections, since email is the key to your other accounts.
• Secure your recovery options: Review and secure your email's recovery options (recovery phone/email, security questions), since attackers target these to take over accounts.
• Review account activity: Periodically check your email's recent activity and active sessions, signing out anything unfamiliar.

Recognize and Avoid Phishing

Email is the main phishing channel, so vigilance matters:

• Be cautious with links and attachments: Be wary of links and attachments in unexpected emails, which may be phishing or malware. Check where links lead before clicking.
• Verify senders and requests: Do not trust an email based solely on its apparent sender (senders can be spoofed). For important or unusual requests, verify through a separate, known channel.
• Watch for phishing signs: Be alert to urgency, requests for credentials or money, generic greetings, and pressure — common phishing signs.
• Log in directly: Log into accounts by navigating directly to the site or app, not by clicking login links in emails.
• Report phishing: Use your email's "Report Phishing" option for phishing emails.

Watch for Account Compromise Signs

Be alert to signs your email may be compromised:

• Check for unauthorized forwarding rules: Attackers who access email often set up forwarding rules to secretly copy your emails. Periodically review your forwarding rules and settings for anything you did not set up.
• Watch for unusual activity: Be alert to unfamiliar logins, sent emails you did not send, or unexpected changes.
• Review connected apps: Review third-party apps connected to your email and revoke untrusted ones.

Manage Your Inbox and Email Use Wisely

Good email habits improve security and privacy:

• Use filters to organize: Set up filters to organize your inbox and manage different types of email.
• Protect your email address: Share your real email selectively. Use temporary email like Temp90 for signups on less-trusted sites, keeping your real email out of databases that lead to spam and phishing.
• Report and manage spam: Report spam to train your filters, and unsubscribe from legitimate senders you no longer want.
• Consider separate emails for different purposes: Some people use separate emails for important accounts, everyday use, and signups, compartmentalizing for security and organization.

Protect Sensitive Information in Email

Be mindful of what is in your email:

• Be cautious sending sensitive information: Standard email is not end-to-end encrypted, so avoid sending highly sensitive information by email where possible, or use more secure methods.
• Be aware email is a record: Your email holds a record of your accounts and information, so securing it protects all of that.
• Clean up sensitive emails: Consider removing or securing especially sensitive emails over time.

Frequently Asked Questions

What are the most important email security best practices?

Secure your email account strongly, since it is the key to your other accounts: use a strong, unique password used nowhere else, and enable strong 2FA (ideally an authenticator app or security key rather than SMS) — one of the most important protections. Secure your recovery options (which attackers target) and review your account activity. Recognize and avoid phishing (being cautious with links and attachments, verifying senders and requests through known channels, and logging in directly), watch for compromise signs like unauthorized forwarding rules, and protect your email address by using temporary email like Temp90 for less-trusted signups.

Why is securing my email account so important?

Because your email is the key to most of your other accounts — password resets for nearly everything go through your email, so whoever controls it can reset passwords and take over your other accounts. Email also holds sensitive information and a record of your accounts, and it is the main channel for phishing. This central role makes email a prime target, and compromising it can cascade into widespread account takeover. So securing your email — with a strong unique password, strong 2FA, secured recovery options, and phishing vigilance — protects not just your inbox but your entire digital life.

How can I tell if my email account has been compromised?

Watch for signs: unfamiliar logins or active sessions, sent emails you did not send, unexpected changes to settings, or password reset notifications you did not request. A particularly important check is your email forwarding rules and settings — attackers who access email often set up forwarding rules to secretly copy your incoming emails (including password resets and 2FA codes), so review these for anything you did not set up. Also review connected third-party apps and revoke untrusted ones. If you suspect compromise, change your password, enable 2FA, remove unauthorized forwarding rules and connected apps, and sign out other sessions.

Conclusion

Your email is one of your most important and most targeted accounts — the key to your other accounts, a holder of sensitive information, and the main channel for phishing — so following email security best practices protects your entire digital life, not just your inbox. Secure your email account strongly as a priority: use a strong, unique password used nowhere else, enable strong 2FA (ideally an authenticator app or security key rather than SMS — one of the most important protections), secure your recovery options (which attackers target), and review your account activity. Recognize and avoid phishing by being cautious with links and attachments, verifying senders and requests through known channels, watching for phishing signs, logging in directly, and reporting phishing. Watch for compromise signs, especially unauthorized forwarding rules that attackers use to secretly copy your emails, and review connected apps. Manage your inbox wisely with filters, protect your email address by using temporary email like Temp90 for less-trusted signups, and consider separate emails for different purposes. Finally, be mindful of sensitive information in email, since standard email is not end-to-end encrypted. By following these email security best practices, you protect your most important digital asset and, through it, your entire online life.
