Email remains one of the most common entry points for cyberattacks – and one of the easiest to overlook.
Whether you manage a personal inbox, a business account, or an entire client portfolio, learning how to secure your email account is one of the most important steps you can take to protect your identity, your data, and your reputation.
From phishing to credential stuffing, attackers constantly look for weak spots.
At Openprovider, we offer the tools and guidance that help you stay ahead – combining domains, DNS management, SSL certificates, and secure email hosting to strengthen your entire email environment.
The main threats to your email account
Your email address is the digital key to almost everything you do online. Once compromised, it can give attackers access to accounts, financial details, or even your clients’ business systems.
Here are the most common threats to be aware of:
Phishing and spoofing
Attackers send deceptive emails that appear to come from legitimate sources – banks, colleagues, or clients. They often copy real domain names or email layouts to trick users into clicking malicious links or sharing credentials.
Credential stuffing and brute force attacks
When hackers obtain passwords from leaked databases, they try those credentials across multiple accounts. Automated brute force tools can test thousands of combinations until one works, especially if your password is short or reused elsewhere.
Man-in-the-middle and session hijacking
This type of attack happens when communication between your device and the server is intercepted. Without SSL/TLS encryption, attackers can read or modify messages while they’re in transit, especially over public Wi-Fi.
Email forwarding abuse
An attacker who gains access to your account can secretly set up forwarding rules, redirecting all incoming mail to another address. This is a stealthy way to spy on your communication or steal sensitive information without detection.

10 essential steps to secure your email account
- Use strong, unique passwords: avoid reusing passwords across different services. Use a password manager to create long, random, and unique combinations for each account.
- Enable two-factor authentication (2FA): adding a second verification step – such as an authenticator app or a hardware key – makes it far more difficult for attackers to break in, even if they know your password.
- Regularly review forwarding and filter settings: check your email rules periodically for unfamiliar forwarding addresses or filters. These can be signs of a compromise.
- Keep your software and email clients up to date: security patches are released frequently to fix vulnerabilities. Keeping your systems updated reduces your exposure to known exploits.
- Avoid using public Wi-Fi for email access: public networks can be insecure and easy to intercept. If you must connect through one, use a VPN to encrypt your traffic.
- Be careful with attachments and links: phishing emails often contain attachments or links that lead to malware. Even if an email looks legitimate, confirm the sender’s domain before you click.
- Monitor login activity and devices: most email platforms allow you to see recent sign-ins. Check regularly for unusual locations or devices you don’t recognize.
- Configure DNS records:use SPF, DKIM, and DMARC to authenticate your emails and prevent others from sending messages that look like they come from your domain. It’s one of the best ways to stop spoofing.
- Use SSL/TLS encryption: always use email services that support SSL/TLS encryption. This ensures that messages remain private and secure as they travel between servers.
- Educate your team or clients: security isn’t just technical – it’s behavioral. Train your staff and clients to recognize phishing attempts, handle passwords safely, and report suspicious messages.
Advanced security measures you should adopt
After implementing the steps above, the next step is consistency.
You should apply and maintain security policies across all of your domains and accounts.
- Start by automating password policies, DNS record checks, and SSL renewals wherever possible. Consider centralizing control through APIs that monitor DNS changes, detect expired SSL certificates, and enforce uniform 2FA requirements.
- Conduct regular audits of access permissions and account activity to reveal vulnerabilities before attackers exploit them.

Frequently asked questions
What’s the best 2FA method for email?
Authenticator apps like Google Authenticator, Authy, or Microsoft Authenticator are more secure than SMS verification, which can be intercepted or redirected through SIM swapping. For even stronger protection, hardware security keys (such as YubiKey) add a physical layer of defense that’s virtually impossible to replicate remotely.
Does password length matter more than complexity?
Yes. Length is the most important factor in password strength. A long passphrase – using random words separated by symbols – is harder to guess or brute-force than a short, complex one. For example, “red-guitar-window-travel” is easier to remember and stronger than “R#2xT!”. Password managers can help generate and store your passwords securely.
Can someone still hack my email if I use 2FA?
While 2FA significantly reduces your risk, it’s not foolproof. Sophisticated phishing attacks can trick users into revealing both passwords and temporary codes. That’s why it’s important to stay cautious, use phishing-resistant authentication methods, and review login notifications promptly if something seems off.
How do I know if my email is compromised?
Watch for signs like login attempts from unfamiliar locations, password reset requests you didn’t make, or unexpected changes to your forwarding rules. You can also check databases like Have I Been Pwned to see if your email address was involved in known breaches. If you suspect a compromise, change your password immediately and enable 2FA.
Can Openprovider security settings help with phishing attacks?
Yes. Proper SPF, DKIM, and DMARC configuration can prevent attackers from sending fake messages from your domain, dramatically reducing phishing exposure for your customers and partners.
