![7 Best Practices for Writing Secure Emails to Avoid Phishing Attacks](https://media.mailhop.org/dmarcreport/images/2022/04/dmarc-alignment-6379.jpg) 

\*\*Phishing remains the #1 initial access vector for cyberattacks, and email authentication (SPF + DKIM + DMARC) is the primary technical defense. Per the [FBI’s 2022 IC3 Report](https://www.ic3.gov/Media/PDF/AnnualReport/2022%5FIC3Report.pdf), 300,497 US-based victims reported phishing incidents in a single year. DMARC with `p=reject` prevents attackers from spoofing your domain in phishing campaigns.

> The support tickets we get after a spoofing incident all start the same way: ‘we didn’t know someone was sending email from our domain,’ says Vasile Diaconu, Operations Lead at DuoCircle. DMARC reporting would have caught it weeks earlier. The cost of monitoring is nothing compared to the cost of a successful impersonation attack.

## 1\. Use a professional and clear email address

Your email address is the first thing people see. A random email can look suspicious. Use a professional email that matches your identity.

**For example**, [carol.smith@yourcompany.com](mailto:carol.smith@yourcompany.com) looks more trustworthy than [carol12345xyz@gmail.com](mailto:carol12345xyz@gmail.com). A clear email address helps others know they are talking to the right person

Also, avoid using free email providers for business emails. Scammers often use fake [Gmail or Yahoo](https://dmarcreport.com/blog/google-and-yahoos-new-email-authentication-policy-for-2024/) accounts.

If you send emails for work, **use a company domain**. This reduces the risk of phishing attacks and builds trust with your contacts.

Moreover, if you need to create professional, error-free emails, tools like [Qozex.com](https://qozex.com/) can help refine your \*\*writing and ensure clarity in your messages. You can also use an [AI changer](https://wordchanger.net/) to adjust tone or replace repetitive terms. This not only improves communication but also helps you build trust and credibility with your recipients.

## 2\. Be cautious with links and attachments

Phishing emails often include fake links and [dangerous attachments](https://www.computerweekly.com/news/366605874/Phishing-links-becoming-bigger-threat-than-email-attachments). One wrong click can let hackers into your system.

Cloudflare reports that deceptive links were the most common phishing method, making up \*\*36% of phishing threats from their analysis of 13 billion emails.

Before clicking any link, hover over it to see where it leads. If it looks strange, do not click. Scammers often use fake websites that look real.

**For example,** instead of paypal.com, they might use **pay-pal-secure.com**.

Attachments can also carry viruses. Avoid opening files from unknown senders. If you must send attachments, use secure file-sharing services instead of attaching them directly. This keeps your emails safer and helps protect sensitive information.

## 3\. Implement strong email authentication methods

![Dmarc alignment](https://media.mailhop.org/dmarcreport/images/2025/03/dmarc-alignment-5580.jpg) 

Hackers can send fake emails that look like they’re from you. [Email authentication](https://dmarcreport.com/blog/why-email-security-matters-and-how-to-get-it-right/)

stops this from happening.

Use [SPF, DKIM, and DMARC](https://dmarcreport.com/blog/how-do-dmarc-spf-and-dkim-work-in-tandem-to-provide-email-security/) to make sure only approved senders can use your domain. These tools tell email providers which emails are real and which are fake. Most email services let you set up these **security features easily**.

But according to Cloudflare, \*\*89% of malicious emails bypassed email authentication methods like SPF, DKIM, and [DMARC](https://dmarcreport.com/).

If you’re unsure, ask your IT team or email provider . Without email authentication, scammers can pretend to be you and trick others. Protect your domain so no one misuses your identity.

## 4\. Avoid sharing sensitive information in emails

\*\*70% of organizations unknowingly share sensitive information during vishing (voice phishing) simulations, according to Keepnet 2024 Vishing Response Report.

Emails are not the safest place to share personal details. Hackers can read emails if they get access.

Never send passwords, credit card details, or other private information over email. If you must share something sensitive, use a secure messaging app or an **encrypted file-sharing service**.

Also, be careful with requests for sensitive data. If someone asks for private information through email, \*\*double-check by calling them or confirming in person. Cybercriminals often pretend to be banks, coworkers, or managers. _Stay alert and protect your information_.

Whereas, if you need to summarize important points before sharing, use a [paragraph summarizer](https://paragraph-generator.com/paragraph-summarizer) to extract key details safely. This tool from \*\*paragraph-generator.com works effectively to shorten your text and highlight key points.

## 5\. Watch out for social engineering tactics

It found from a study that \*\*74% of security breaches involve human error or social engineering.

Phishing emails don’t just trick your computer. They trick your mind too. Scammers use emotions like fear, urgency, or curiosity to make you act fast.

\*\*For example, \*\*an email might say, \*\*“Your account will be locked in 24 hours! Click here to fix it.” \*\*This rushes you into clicking a fake link.

Be careful with emails that create pressure. Take a moment to think before you act. _Check the sender, verify links, and never share details just because an email sounds urgent_. If something feels off, it probably is. Stay smart and trust your instincts.

But if you receive an important urgent email and are unsure how to respond, an [AI email writer](https://sentencerewriter.net/ai-email-generator) can help you craft a professional and cautious response. As we evolve with digital tools, it’s important to [Humanize AI](https://humanizeaitext.ai/) by implementing emotional intelligence into AI-driven security features. Using an [AI humanizer](https://www.humanizeai.io/) can make your defense systems not only more efficient but also more intuitive at detecting phishing attempts disguised under social engineering tactics.

## 6\. Use multi-factor authentication (MFA) for extra security

Passwords are not enough to keep emails safe. Hackers can steal them. That’s why [multi-factor authentication (MFA)](https://www.ibm.com/think/topics/multi-factor-authentication) is important.

MFA adds another step before you log in, like a code on your **phone or a fingerprint scan**. Even if someone steals your password, they can’t access your email without this extra step.

Most email providers offer MFA for free. You should turn it on right now if you haven’t already. It’s one of the easiest and best ways to protect your email from cyberattacks.

## 7\. Educate yourself and your team on email security

Phishing attacks keep changing. That’s why learning about [email security](https://dmarcreport.com/blog/why-email-security-matters-and-how-to-get-it-right/) is important.

Companies should train employees to recognize phishing emails. Even one careless mistake can cause data breaches. Regular workshops help people **stay aware of new threats**.

_If you work alone, stay updated by reading security tips from trusted websites_. Cybercriminals use new tricks all the time. Knowing what to look for helps you stay ahead.

Education is one of the best ways to fight phishing attacks. The more you know, the safer you are.

## 8\. Enable email encryption for sensitive messages

![Dmarc analyzer](https://media.mailhop.org/dmarcreport/images/2025/03/dmarc-analyzer-3044.jpg) 

\*\*Encryption protects emails \*\*by turning them into unreadable text. Only the right person can unlock and read the message.

If you send confidential emails, use encryption tools like \*\*ProtonMail or Outlook’s built-in encryption. _This ensures that even if someone intercepts your email, they can’t read it_.

Many businesses already use encryption, but check your settings to be sure. Without it, sensitive data in your emails could be at risk. Don’t take that chance - \*\*encrypt important messages \*\*whenever possible.

## 9\. Regularly update email security settings and software

Technology changes fast, and so do [cyber threats](https://www.securityweek.com/from-warnings-to-action-preparing-americas-infrastructure-for-imminent-cyber-threats/). Keeping your email security settings and software updated helps block phishing attacks.

Make sure your [spam filters](https://www.fortinet.com/resources/cyberglossary/spam-filters) are strong. Update your \*\*antivirus and email apps to the latest versions. These updates often fix security flaws that hackers try to exploit.

Also, review your email account’s security settings. \*\*Enable extra protection where possible. A little effort now can prevent big problems later. _Stay ahead of cybercriminals by keeping everything up to date_.

## Wrapping up

[Phishing attacks](https://www.infosecurity-magazine.com/news/mobile-phishing-attacks-surge-16/) are dangerous, but they can be stopped. By **following these best practices**, you can write safer emails and protect yourself from cyber threats.

Cybercriminals look for easy targets. Don’t be one of them. Stay smart, stay safe , and always protect your email. A little caution goes a long way in **keeping your information secure**.
