What’s email security and compliance?

Email is the most important means of business communication. It’s also the cheapest, fastest, and most accessible option. You can also use emails to communicate easily with individuals or groups. That said, due to its large-scale usage and accessibility, email is one of the largest cyberattack vectors. Clearly then, email security is very important.

That’s where the need to meet strict email compliance requirements comes in. Email security ensures the safety of the data, identities, and information transmitted over emails. Email compliance also ensures that the transmitted data in the email meets the requirements of all the regulatory and governing bodies involved.

In this article, I’ll explain what security and privacy steps you can take to help you stay email compliant. I’ll also walk you through creating an email compliance strategy and the top email compliance frameworks and tools. Let’s start with the definition first! 

What Is Security and Privacy Compliance for Email?

As I mentioned, emails are an easy, fast, and efficient means of business communication. They’re not secure. In fact, anyone intercepting the emails can read their contents. Luckily, governments and regulatory bodies have set specific requirements to protect individuals and corporations. GDPR, CCPA, HRPA, and PCI DSS are some requirements. These regulatory bodies oversee the rules, regulations, and data security practices a company implements, including the emailing systems.

Any growing company leverages email marketing to acquire an audience and scale its business and operations. So, you need to know the laws around email marketing before you start doing it.

Email Marketing: 5 Regulatory Bodies and Frameworks

A large volume of personally identifiable information (PII) could be at risk of cyberattacks through unsecured email marketing. To prevent these mishaps, governments and governing bodies across the globe have defined their laws and regulations. Companies planning to do email marketing must also follow these guidelines. What are these guidelines, though? You’ll find different laws worldwide that guide the use of email marketing for commercial purposes in specific nations or provinces. 

Here are 5 of the data regulatory bodies and frameworks:


HIPAA (Health Insurance Portability and Accountability Act) is a data security and protection law. The Department of Health and Human Services in the United States introduced this law. HIPAA’s main objective is to protect the patients’ data like medical and health information. This information could be about doctor visits, drug and medication details, etc. 

2. SOC 2

The AICPA (American Institute of Certified Public Accountants) first introduced SOC 2 (Service Organization Control). This process provides effective security and compliance standards for a company’s security, integrity, privacy, and confidentiality. SOC 2 also cares about the availability of the services that the company offers. 


General Data Protection Regulation (GDPR) is a European law. It regulates the policies and laws in place for data privacy and protection in the European Union and the European Economic area. All companies dealing with European citizens’ data must also comply with the GDPR policies. 


The CAN-SPAM (Controlling the Assault of Non-Solicited Pornography And Marketing) is a law passed first in 2003. It serves as the United Nation’s first law in place to regulate commercial emails and email marketing. CAN-SPAM also covers all commercial messages and does the same for B2B and B2C companies. 


CASL (Canada’s Anti-Spam Legislation) is a Canadian law that regulates and protects individuals (consumers) and businesses from digital threats and misuse of technology. This law has been protecting Canadian nationals from several forms of digital threats like SPAM attacks, malware, and phishing attacks since 2014. 

Next, let’s look at ways to stay email compliant.

Practices to Stay Email Compliant

Some of the most important aspects of email marketing that allow you to comply with email marketing laws and regulations are as follows:

  • Ensuring you have permission to email people
  • Avoiding the use of misleading headers
  • Avoiding sending explicit content
  • Ensuring you identify your email as an advertisement
  • Including your sender’s details like email address and registered address
  • Providing users with a choice to opt-out of the email subscription

You must follow all laws and regulations. Moreover, it’s your responsibility to take ownership of the email marketing campaign even though you outsource it to a different firm. Assessing the rules corresponding to your business, educating your employees, and following industry trends are great ways to ensure email compliance.
