10 Email Security Best Practices to Stop Scams in 2026

By Josh C.

In 2026, email remains the number one attack vector for cybercriminals. Losses from Business Email Compromise (BEC) and phishing scams continue to climb into the billions annually, a trend confirmed by the FBI's Internet Crime Complaint Center (IC3). Your inbox is not just a communication tool; it's a direct gateway to your financial information, personal data, and digital identity, making it a primary target for fraud.

Recent reports from CISA highlight a surge in AI-powered phishing campaigns that create hyper-realistic, personalized attacks targeting everyone, especially older adults and busy professionals. These are not the typo-ridden scams of the past. They are carefully constructed operations designed to steal credentials, drain bank accounts, and commit identity theft. Protecting your inbox is no longer optional-it's a critical line of defense for your personal and financial security.

This guide moves beyond generic advice to provide a prioritized, actionable roundup of email security best practices. We will break down ten essential strategies, offering clear how-to steps to create a comprehensive shield for your digital life. You will learn how to:

• Secure your account with multi-factor authentication and strong passwords.
• Identify and report sophisticated phishing attempts before they cause harm.
• Configure your email client to reduce your attack surface automatically.
• Safely handle attachments and links to prevent malware infections.

We'll also discuss setting up account recovery plans and provide guidance tailored for seniors and caregivers. For ongoing protection against the latest phone, SMS, and email scams, consider a dedicated tool. The gini help app, available on both the Google Play Store and the Apple App Store, provides real-time alerts and scam-blocking features, adding another layer of defense. This listicle will empower you and your family with the knowledge to stay one step ahead of attackers.

1. Enable Multi-Factor Authentication (MFA) on Email Accounts

Think of your password as a front door lock. It’s a good first step, but a determined intruder might find a way to pick it. Multi-Factor Authentication (MFA) adds a deadbolt, requiring a second form of verification to prove it’s really you. This means that even if a criminal steals your password through a phishing scam or data breach, they still can’t access your email account without that second factor.

This method is a cornerstone of modern email security best practices, popularized by major providers like Google (Gmail), Microsoft (Outlook/365), and Apple (iCloud). For a practical guide on implementing this crucial defense, refer to a Multi-Factor Authentication (MFA) how-to.

How to Implement MFA Effectively

Setting up MFA involves choosing a second verification method. While SMS text messages are common, they are vulnerable to SIM-swapping attacks. A more secure approach is using an authenticator app.

• Authenticator Apps: Use an app like Google Authenticator, Microsoft Authenticator, or Authy. These generate time-sensitive codes directly on your device, independent of your phone number.
• Backup Codes: When you enable MFA, you'll receive a set of backup codes. Print these out and store them in a secure physical location, like a safe or a locked file cabinet. They are your lifeline if you lose your primary device.
• Recovery Process: Test your account recovery process before you need it. This ensures you understand the steps to regain access and prevents being locked out during an emergency.
• Device Trust: For caregivers assisting seniors, many services allow you to "trust" a specific device. This reduces how often you need to re-authenticate on a secure home computer, simplifying daily use without sacrificing protection on unknown devices.

Recent data from the FBI's Internet Crime Complaint Center (IC3) consistently shows that business email compromise and personal account takeovers lead to billions in losses, a threat MFA directly counters. To further guard against scams that try to trick you into revealing MFA codes or other personal data, consider using a scam protection tool. Apps like the Gini Help app for Google Play and the App Store can help identify and block fraudulent communications.

2. Implement Advanced Email Filtering and Spam Detection

Think of your inbox as a digital mailbox on a busy street. Advanced email filtering acts as a dedicated security guard, inspecting every piece of mail before it lands in your box. It uses smart algorithms and artificial intelligence to identify and quarantine spam, phishing attempts, and malicious emails, stopping them before you ever see them. This is a critical element of modern email security best practices.

Unlike basic filters that just look for specific keywords, modern systems analyze sender reputation, message patterns, suspicious links, and hidden code within attachments. This is especially vital for seniors, who are often targeted by sophisticated scams impersonating trusted organizations like the Social Security Administration, banks, or tech support services. Leading providers like Google and Microsoft report that their advanced filters block over 99.9% of spam and phishing threats from reaching users. For a deeper look into this topic, you can learn more about how to stop email spam.

How to Implement Advanced Filtering Effectively

Most email services have powerful filters built-in, but you can optimize them for better protection. The goal is to create a strong, intelligent barrier against threats.

• Enable Maximum Protection: Go into your email settings (like in Gmail or Outlook) and find the spam or junk mail options. Set the filtering level to its highest or most aggressive setting to catch more suspicious messages.
• Check Your Quarantine Folder: Occasionally check your spam or junk folder. Sometimes, a legitimate email can be incorrectly flagged (a "false positive"). By marking it as "not spam," you help train the filter to be more accurate in the future.
• Verify Senders: Teach yourself and loved ones to hover the mouse cursor over the sender's name to reveal the actual email address. Scammers often use a familiar name but a strange, unofficial email address to trick you.
• Review Quarantine Logs: For business or advanced accounts, regularly review quarantine reports. This helps you understand what is being blocked and allows you to adjust the filter’s sensitivity to better suit your needs.

A recent report from the Anti-Phishing Working Group (APWG) noted a record number of unique phishing attacks, highlighting the growing need for automated defenses that can adapt to new threats. To add another layer of security, especially against scams that might bypass initial filters, use a dedicated protection tool. Download the Gini Help app for Google Play or the App Store to screen and block fraudulent communications before they cause harm.

3. User Awareness, Phishing Recognition, Family Education, and Reporting

While technology provides essential guards, the most effective defense is a vigilant human. User awareness and family education form a proactive firewall against scams. This practice involves training yourself and your loved ones to spot phishing attempts and social engineering tactics, creating a culture where it’s safe to ask for a second opinion on a suspicious message. This is a vital component of any robust email security best practices, especially for protecting seniors who are frequently targeted by impersonation scams.

This human-centric approach is promoted by cybersecurity leaders like the SANS Institute and the AARP Fraud Watch Network. It focuses on turning potential victims into the first line of defense. The FBI's constant warnings about the financial devastation caused by Business Email Compromise (BEC) and personal fraud underscore the need for sustained vigilance.

How to Build a Human Firewall

Effective awareness is about building habits and communication protocols, not just memorizing rules. Start with these practical steps for yourself and your family.

• Scrutinize Senders: Teach everyone to carefully inspect the "From" address. Scammers often use domains that are one letter off from a legitimate company (e.g., "micros0ft.com" instead of "microsoft.com").
• Hover Before You Click: Always hover your mouse cursor over links in an email before clicking. The actual web address will appear in a small pop-up or at the bottom of your browser window; if it looks suspicious or doesn't match the link text, don't click.
• Establish Family Protocols: Create a simple rule: "Never respond to urgent requests for money or personal information without calling to verify." Use a trusted phone number from your contacts, not one provided in the email. Some families even use a secret "code word" to confirm identities over the phone.
• Report Everything: Use the "Report Phishing" or "Report Junk" button in your email client (Gmail, Outlook). This helps train the service's filters. For caregivers and family, create an open environment where a senior feels comfortable forwarding a suspicious email for review without feeling foolish.

For an added layer of real-time protection that can catch what a user might miss, consider a scam protection app. Download the Gini Help app for Google Play and the App Store to analyze messages and provide instant threat alerts, reinforcing good security habits.

4. Verify Sender Identity Before Acting on Email Requests

Scammers create fake emails that look exactly like they’re from your boss, your bank, or a government agency. Their goal is to trick you into transferring money or giving up personal information. This tactic, known as Business Email Compromise (BEC) or email spoofing, relies on trust and urgency. Verifying the sender’s identity through a separate, trusted channel before you act is one of the most effective email security best practices.

This simple habit of verification is strongly promoted by agencies like the FBI’s Cyber Division and the Secret Service Financial Crimes Task Force. It directly counters attacks that cost individuals and businesses billions. For a deeper dive into spotting these fakes, review this guide on how to detect fake emails.

How to Verify Sender Identity Effectively

The key is to use a communication method outside of the suspicious email itself. Never use phone numbers or links provided in the email you are questioning.

• Confirm by Phone: If you receive an urgent financial request from a colleague or executive, call them on a known, trusted phone number to confirm. Do not reply to the email or use the number listed in their email signature.
• Check the Email Address: Scrutinize the sender’s email address character-by-character. Criminals often create addresses that are nearly identical, like substituting “rn” for “m” (e.g., “support@acrne.com” instead of “support@acme.com”).
• Establish Protocols: For businesses, create a clear policy that any request for a wire transfer or payment change must be confirmed verbally or through a secondary channel. For families, establish a rule that you will call to confirm any unexpected request for money.
• Trust Your Instincts: Be wary of emails that use urgent or threatening language like “act immediately,” “your account is suspended,” or “confirm payment urgently.” Government agencies like the IRS or Social Security Administration will not initiate contact via email to demand payment or personal information.

The FBI's Internet Crime Complaint Center (IC3) reported that BEC scams resulted in an adjusted loss of over $2.9 billion in 2023 alone, highlighting the critical need for verification. To add another layer of defense against these manipulative tactics, a scam protection tool can be invaluable. Install the Gini Help app from Google Play or the App Store to help identify and block fraudulent messages before they can cause harm.

5. Keep Email Client and Operating System Patched and Updated

Think of your email software and operating system as the foundation of your digital house. Over time, tiny cracks and weaknesses (vulnerabilities) are discovered. Software updates are like a maintenance crew that comes to repair these cracks before an intruder can exploit them to get inside. Failing to update leaves your system exposed, allowing a single malicious email attachment or link to compromise your entire device.

This foundational practice is a critical component of email security best practices, championed by security authorities like CISA and major vendors like Microsoft, Apple, and Google. For instance, the 2024 "Pwn2Own" hacking contest demonstrated how unpatched vulnerabilities in major software could be exploited in minutes, reinforcing the urgency of applying security patches as soon as they are available.

How to Implement Updates Effectively

The key is to make updates automatic and non-disruptive. This removes the burden of remembering to check and ensures protection is applied as soon as it's available.

• Enable Automatic Updates: Configure your devices to download and install updates automatically. This can be done through Windows Update, macOS Software Update, and settings on your iOS or Android device. This is especially helpful for seniors, as it removes the need to make a security decision.
• Schedule Restarts: Set updates to install during off-hours, like overnight, to avoid interrupting your work or daily activities.
• Replace Old Hardware: If a device is so old that it no longer receives security updates from the manufacturer (like an old iPhone or Windows 7 PC), it is a permanent security risk. It should be replaced to ensure you are protected against new threats.
• Stay Informed: Major security flaws often make the news. Being aware of significant threats can reinforce the importance of not delaying a critical patch.

The Verizon 2024 Data Breach Investigations Report highlights that exploiting vulnerabilities remains a primary pathway for attackers. Regular updates directly counter this threat. To supplement these system-level protections, download the Gini Help app for Google Play and the App Store to identify and block malicious links and attachments that try to exploit unpatched software.

6. Use Strong, Unique Passwords and a Password Manager

Using the same password for multiple accounts is like using the same key for your house, car, and office. If a thief gets one key, they get access to everything. A strong, unique password for your email account ensures that even if another service you use is compromised in a data breach, your primary communication hub remains secure. This is a foundational email security best practice.

The challenge is creating and remembering dozens of complex passwords. This is where password managers come in. Tools like Bitwarden, 1Password, and Apple's iCloud Keychain securely generate, store, and autofill credentials, removing the mental burden. While LastPass has served millions, a 2022 security incident highlighted the need to choose providers with transparent security audit records. To further fortify your accounts, consider leveraging dedicated password management solutions such as Passflow.

How to Implement Strong Password Practices

A password manager is your digital vault, but it's only as secure as its master password. Setting this up correctly is the most critical step.

• Create a Strong Master Passphrase: Instead of a complex, random string, use a long but memorable passphrase like BlueMoon!Travels2024. This is easier to recall but very difficult for computers to guess.
• Enable Biometrics: On your phone and computer, enable fingerprint or face recognition to unlock your password manager. This adds a convenient layer of security.
• Use Generated Passwords: Let the password manager create new passwords for your accounts. Aim for at least 16 characters with a mix of uppercase letters, lowercase letters, numbers, and symbols.
• Store Backup Codes Securely: Just like with MFA, your password manager will provide a recovery key or emergency sheet. Print this and store it in a physical safe or locked drawer. Never share this with anyone.
• Enable Breach Monitoring: Most reputable password managers can alert you if one of your stored passwords appears in a known data breach, prompting you to change it immediately.

The 2023 Verizon Data Breach Investigations Report found that stolen credentials were a factor in nearly 50% of all breaches. To learn more specific techniques, you can explore this guide on how to protect an email with a password. For an added layer of defense against phishing attempts that try to steal your new, strong passwords, use a scam protection app like the Gini Help app for Google Play and the App Store.

7. Disable Automatic Image Loading and Preview Panes in Email Clients

Opening an email can feel harmless, but hidden within its design are features that can compromise your privacy and security. Many emails contain tiny, invisible images called tracking pixels or web beacons. When your email client automatically loads these images, it sends a signal back to the sender, confirming that your email address is active and that you opened their message. This action validates your address for spammers and scammers, leading to more junk mail.

Even more concerning, the preview pane in your email client, which shows a snippet of an email without you fully opening it, can automatically load malicious content. This could expose your computer to malware or redirect you to a phishing website without a single click. Disabling these automatic features is a critical email security best practice that reduces your exposure to these hidden threats.

How to Implement This Safely

Most major email clients give you control over these settings, allowing you to regain control over what content loads and when. While providers like Gmail now route images through their own secure servers to mitigate some risks, directly controlling image loading is still the safest approach.

• In Microsoft Outlook: Go to File > Options > Trust Center > Trust Center Settings > Automatic Download. Check the box for "Don't download pictures automatically in standard HTML e-mail messages or RSS items."
• In Apple Mail: Navigate to Mail > Settings (or Preferences) > Viewing. Uncheck the box for "Load remote content in messages."
• In Gmail: Go to Settings > See all settings > General. Select "Ask before displaying external images."
• Whitelist Trusted Senders: After changing these settings, emails from unknown senders will appear without images. You can typically click a button to "display images" for that specific message. For senders you trust, like family or a doctor's office, you can add them to a safe-sender list so their images always load.

A recent alert from cybersecurity agencies like CISA highlights how threat actors use seemingly benign email features to execute sophisticated phishing campaigns. By disabling automatic image and content loading, you break a key link in the chain that scammers use to verify targets and launch attacks. To add another layer of defense against fraudulent messages that slip through, download the Gini Help app for Google Play and the App Store to analyze suspicious communications and help you identify potential threats.

8. Be Cautious of Email Attachments and Suspicious File Types

Think of an email attachment as a package left on your doorstep. Even if the sender's name looks familiar, you can’t be sure what’s inside until you open it. Cybercriminals use this method to deliver malware, ransomware, and other malicious software directly to your device. Opening a seemingly innocent document can execute hidden code that steals your information or locks your files.

This tactic is a persistent threat in modern cybersecurity, with solutions from Microsoft Defender to Google Safe Browsing working to intercept dangerous files. The infamous Emotet malware, for instance, spread widely through macro-enabled Word documents sent as email attachments. Vigilance against unexpected files is a core principle of email security best practices.

How to Handle Attachments Safely

Adopting a cautious mindset is your best defense. Before you click to open any attachment, pause and assess the situation with these steps.

• Verify the Unexpected: If you receive an attachment from a known contact but weren’t expecting it, do not open it. Contact the sender through a different method, like a phone call or text message, to confirm they sent it.
• Scan Before Opening: Instead of double-clicking an attachment, right-click and save it to your computer. Then, use your updated antivirus software to scan the file. For extra security, upload the file to a free online scanner like VirusTotal.com to check it against dozens of security engines.
• Block Dangerous File Types: Be extremely wary of compressed files (.zip, .rar) and executables (.exe). Scammers use archives to hide malicious contents. Many email clients allow you to create rules to automatically block or flag emails with these file types from external senders.
• Disable Macros: Malicious Office documents (.doc, .xlsx) often prompt you to "Enable Content" or "Enable Macros." Do not do this unless you are 100% certain the source is legitimate and the macros are necessary.

Recent Verizon DBIR reports consistently highlight that email attachments are a primary delivery vehicle for malware. For seniors and their caregivers, it’s vital to understand that legitimate organizations almost never send unsolicited software or critical forms as executable files. To add another layer of defense against the social engineering tactics that trick people into opening bad attachments, download the Gini Help app for Google Play and the App Store to help detect and block fraudulent communications before they cause harm.

9. Configure Email Authentication Protocols (SPF, DKIM, DMARC)

Think of your email address as a return address on a physical letter. Anyone can write a fake one to trick the recipient. Email authentication protocols act as a digital postmark, verifying that an email message actually came from the server it claims to be from. This technical trifecta (SPF, DKIM, DMARC) is one of the most powerful email security best practices for preventing domain spoofing, where scammers impersonate your organization to defraud customers, partners, and employees.

These standards are essential for any business or individual with a custom domain. Their importance is underscored by industry leaders like Google and Microsoft, which now have stricter authentication requirements for senders to protect users from spam and phishing. For example, Google's updated enforcement rejects a significant percentage of unauthenticated emails, making DMARC non-negotiable for reliable delivery. A technical overview is available from the industry group at DMARC.org.

How to Implement Email Authentication Effectively

Setting up SPF, DKIM, and DMARC involves adding specific records to your domain's DNS settings. While technical, many domain registrars and email providers offer guided setups. The process is typically phased to avoid disrupting legitimate email flow.

• Implement SPF First: Create a Sender Policy Framework (SPF) record that lists all the mail servers authorized to send email on behalf of your domain. This includes third-party services like marketing platforms or CRMs.
• Set Up DKIM: Generate DomainKeys Identified Mail (DKIM) signatures. This adds a unique digital signature to your outgoing emails, which receiving servers can verify against a public key in your DNS.
• Deploy DMARC Gradually: Start with a DMARC policy in "monitor" mode (p=none). This allows you to receive reports on who is sending email from your domain without affecting mail delivery.
• Progress to "Quarantine" and "Reject": Once you've analyzed the reports and are confident all legitimate sources are authenticated, move to a p=quarantine policy (sends unauthenticated mail to spam) and finally to p=reject (blocks it entirely).

The FBI's latest Internet Crime Report highlights Business Email Compromise (BEC) as a primary source of financial loss, often enabled by domain spoofing. Implementing these protocols is a direct defense. To protect yourself from sophisticated scams that bypass even these measures, download the Gini Help app for Google Play and the App Store to help analyze and flag suspicious communications before you engage.

10. Monitor Email Account Activity and Set Up Security Alerts

Think of your email account's security dashboard as a home security system. It actively monitors for suspicious entry attempts and alerts you to potential dangers in real time. Regularly checking your account activity and enabling security notifications provides an essential early warning system, allowing you to react swiftly if a criminal gains unauthorized access. This proactive monitoring is a critical layer in any email security best practices strategy.

This practice is strongly promoted by all major email providers, including Google, Microsoft, and Apple, who provide built-in tools to track account access. By understanding what normal activity looks like, you can immediately spot anomalies like logins from unrecognized devices or foreign locations. For an in-depth look at how Google handles this, you can explore the Google Account Security center.

How to Effectively Monitor Your Account

Setting up alerts and knowing where to look are key. Most services centralize this information in your account's security settings, making it simple to review who, where, and when your account has been accessed.

• Review Login History: Periodically check your device activity. For Gmail, this is found at myaccount.google.com/device-activity. For Microsoft accounts, review recent activity at account.microsoft.com/security. This shows all devices and locations that have accessed your account.
• Enable Security Alerts: Configure your account to send you an email or text message when a new device signs in or a suspicious login is detected. This provides an immediate notification of a potential breach.
• Prune Trusted Devices: Over time, you may accumulate a list of old phones, tablets, or computers that are authorized to access your account. Regularly remove any devices you no longer own or use from this trusted list.
• Support for Seniors: Caregivers can help older adults by adding a family member’s email or phone number as a trusted contact to receive security alerts. This creates a safety net, ensuring that suspicious activity is noticed and addressed quickly.

The Verizon 2023 Data Breach Investigations Report (DBIR) highlighted that the use of stolen credentials remains a primary method for account takeovers. Vigilant monitoring directly counters this threat by flagging the unauthorized use of your credentials. To supplement these alerts and better identify phishing attempts that lead to compromise, download the Gini Help app for Google Play and the App Store to help filter fraudulent messages designed to steal your login information.
