Just imagine: cybercriminals hacked your email, disseminated malware across your clients, and stole their data – finances are lost, reputation is stomped, and loyal users are gone forever.
Every business that overlooks email security is at risk. Compromise your security once, and it may take months or even years until email deliverability and trust recover.
Read on to learn the most tangible email marketing threats and how to prevent them.
The larger the scale of your email campaign, the more sensitive data you store, which is exactly what criminals need.
Their job is to intrude into your system and extract valuable data, which can cause not just financial losses, but lasting damage to your brand’s reputation.
Data breaches can also trigger legal consequences.
If sensitive data from your mass emails leaks, you may breach compliance with the GDPR in Europe, the CCPA in the United States, and possibly other national and state-level laws.
These malicious schemes can damage your mass email campaign, regardless of the goals you’re after:
| Phishing | There are 3.4 billion phishing emails sent daily to deceive individuals into disclosing their personal information. As a result, criminals can impersonate others, commit fraud, or drain bank accounts. |
| Malware attacks | While phishing doesn’t use software, malware relies on baiting recipients into downloading files infected with viruses. By infecting your system, they steal, encrypt, or destroy data, often as part of a ransomware attack. |
| Data Breaches | As your bulk email dissemination proceeds, you accumulate a pool of user data, starting from card information and finishing with passport numbers. Criminals are constantly on the lookout for a breach in your system that allows them to steal sensitive data. |
| Spam complaints | If email providers tag your emails as spam, which happens to noisy letters that arrive without asking for permission, don’t even check email deliverability – it’s forever dead. |
| Email spoofing | It’s the practice of impersonating email addresses to steal valuable information, such as credit card details, passwords, or other sensitive data. |
Luckily, there are effective practices to prevent the abovementioned and other schemes from harming your lead generation, sales, or other email campaigns.
Let’s explore how to incorporate them.
Don’t overlook simple yet powerful tools like 2FA. With its help, you reinforce your security with an extra layer of protection, which, in most cases, is extremely difficult for attackers to bypass.
Why? You can’t forge a US phone number, unless, perhaps, you’re an FBI agent.
These email providers are famous for their strong security features that, when utilized properly, make your accounts nearly impossible to crack:
The most notable aspect of these providers is their open-source architecture, which enables anyone to audit their program code.
It promotes transparency and helps identify vulnerabilities before they can be exploited.
The majority of these mailboxes also have a zero-access infrastructure, which means that only you have access to encrypted email attachments even providers can’t reach those.
If your brand becomes popular and your email authentication protocols aren’t configured, you become an easy target for spoofing.
To avoid that, you must set these protocols up:
These are also email deliverability tools, as providers are more likely to land authenticated emails in the inbox instead of the spam folder.
Moreover, some providers, such as Google or Microsoft, require mass email senders to implement SPF, DKIM, or DMARC, making these standards industry standards.
Whether you’re using the built-in Windows protection tool, antivirus software, or another security measure, it receives regular updates that you must install to eliminate vulnerabilities and maximize security.
If you’re an enterprise with multiple devices, it’s essential to install security patches across them all. Depending on the scale of your system, you may need to hire a security maintenance expert.
As you discovered earlier, poorly designed emails compromise your email protection. You can avoid that by using a checklist with these bullet points:
By leveraging an email marketing platform, such as MailChimp, you acquire valuable metrics, including unsubscribe rates, spam flags, and bounce rates.
This information sheds light on the effectiveness of your email marketing, suggesting whether you should adjust your approach.
Also, don’t forget to consider the time at which you send emails. If your dissemination occurs at night, when users are unlikely to interact, providers can consider your emails irrelevant and reduce your deliverability.
You must explain to people with access to your mailbox that it’s strictly prohibited to open email-received links and files.
If you want to take your security measures to the next level, you can hire security specialists to train your team in detecting suspicious emails, verifying them, and so on.
Even if your system cracks, you can ensure that the most sensitive data isn’t intercepted by protecting it with additional encryption.
You can implement it at several levels:
If you want to step beyond the basics and make security an actual part of your working culture, consider these practices:
| Security training | Hire security specialists to train your employees to identify and counter the latest online fraud practices. |
| Cross-department collaborations | CEOs of large companies should establish effective communication between departments to ensure security through coordinated efforts. |
| Ethical hacking | Simulate hacking attacks on your team to enable them to learn and react to threats in real-time. |
| Data back-ups | Ensure that you copy all important data from your mailbox to restore it if hackers compromise it. |
| Secure email gateways | Careful gateway adjustment prevents the installation of viruses, data loss, spam, and other threats. |
Given the increasing number of cyberattacks, businesses must prioritize cybersecurity. Ignoring it puts finances, reputation, and even legal standing at risk.
By incorporating two-factor authentication (2FA), up-to-date software, and other security guidelines outlined on this page, you build a barrier between criminals and your company’s sensitive data, shielding it from all detrimental threats.
