GDPR vs. CAN-SPAM: Email Compliance Compared

Sending marketing emails? You need to follow the rules - or face serious penalties.

GDPR (Europe) and CAN-SPAM (U.S.) are the two key email regulations you need to know. Here’s the quick difference: GDPR requires opt-in consent before emailing, while CAN-SPAM allows unsolicited emails as long as there’s a clear opt-out option.

Why does this matter?

• GDPR fines: Up to €20 million or 4% of global revenue.
• CAN-SPAM fines: $43,280+ per email violation.
• Non-compliance can also damage your sender reputation, leading to blocked emails and lost trust.

If you’re emailing globally, you must comply with both laws. To simplify, adopt GDPR’s stricter rules universally. This ensures compliance and builds trust with your audience.

Quick Overview:

• GDPR: Covers EU citizens globally, focuses on privacy and explicit consent.
• CAN-SPAM: U.S.-focused, regulates transparency and opt-out mechanisms.

Learn how to meet both standards and avoid costly mistakes.

Understanding GDPR

The General Data Protection Regulation (GDPR) is the European Union's data protection framework, but its reach extends far beyond Europe. If you're running email campaigns, grasping GDPR's requirements is not just useful - it's essential.

Where GDPR Applies

GDPR applies to any organization, anywhere in the world, that processes the personal data of EU citizens or residents. And it’s not limited to email marketing. Whether you're collecting email addresses, tracking website activity, or storing purchase histories, GDPR governs how you handle that information.

One key benefit of GDPR is its uniformity. Before its introduction, each EU country had its own data protection laws, creating a maze of compliance requirements. Now, businesses across the EU operate under a single, consistent framework. Beyond Europe, GDPR has influenced privacy regulations worldwide, with many countries adopting similar rules. For businesses engaging with global audiences, understanding GDPR doesn’t just ensure compliance within the EU - it also provides a glimpse into the evolving global landscape of privacy standards.

GDPR Email Requirements

Under GDPR, businesses must obtain explicit, documented consent before sending marketing emails. Unlike opt-out systems, where users are automatically enrolled, GDPR requires individuals to take a clear, affirmative action - like checking an empty box or clicking a confirmation button - to give their consent. Pre-checked boxes? Those are a no-go.

Double opt-in is widely regarded as the gold standard for compliance. After someone signs up, send a verification email to confirm their subscription. This process not only secures clear proof of consent but also ensures the individual genuinely wants to receive your emails.

GDPR also grants EU residents several rights regarding their personal data. They can access the data companies hold about them, request its deletion (the "right to be forgotten"), and expect transparency about how their data is collected, used, and stored. Businesses must implement strong security measures to protect this data and clearly communicate how long it will be retained and for what purposes.

While GDPR provides businesses some flexibility in how they meet these requirements, it demands careful interpretation to ensure all individual rights are respected. Next, we’ll dive into the enforcement mechanisms and penalties that make GDPR compliance a priority no business can ignore.

GDPR Penalties and Enforcement

GDPR enforcement comes with some of the harshest penalties in the world. Companies can face fines of up to €20 million or 4% of their global annual revenue - whichever is higher. For example, a company generating $1 billion in revenue could face penalties as high as $40 million.

Take Amazon’s case: in January 2022, Luxembourg's data protection authority fined the company €746 million for issues related to targeted advertising and inadequate consent practices. Similarly, in 2021, Germany’s Hamburg data protection authority fined H&M €35.3 million for unlawfully collecting and storing employee data. These cases illustrate how GDPR applies across industries and operational practices.

In 2023 alone, fines imposed by EU regulators exceeded €1.2 billion, reflecting the growing intensity of enforcement. Each EU country has its own data protection authority responsible for investigating complaints, conducting audits, and issuing fines. Individuals also have the right to sue organizations directly for damages caused by data breaches.

For businesses handling email systems, GDPR compliance isn’t optional - it’s a necessity. Email infrastructure should support secure data storage, encryption, and detailed consent tracking. Features like SSL encryption, SPF, DMARC, and DKIM protocols are essential for securing communications. Additionally, systems must enable users to easily opt out or request data deletion, ensuring compliance with GDPR’s stringent requirements.

Understanding CAN-SPAM

Unlike GDPR’s consent-based model, the U.S. approach to email regulation under CAN-SPAM focuses on transparency and giving consumers the ability to make choices. The Controlling the Assault of Non-Solicited Pornography and Marketing Act - commonly called CAN-SPAM - is the primary law governing commercial email in the United States. Passed before GDPR, it takes a different route to compliance, emphasizing openness and consumer autonomy rather than requiring prior consent.

Where CAN-SPAM Applies

CAN-SPAM applies to all commercial emails sent to recipients in the U.S., making it essential for anyone sending marketing emails to American inboxes to comply. If your email campaigns target U.S. consumers, you are obligated to follow the rules set forth by this law.

The law specifically regulates commercial emails - those primarily intended to advertise or promote products or services - and aims to curb deceptive practices. However, one sticking point is its vague stance on international enforcement. While it doesn’t explicitly state whether businesses outside the U.S. must comply, the general rule is clear: if your emails land in American inboxes, CAN-SPAM applies.

CAN-SPAM Email Requirements

Unlike GDPR, which requires users to opt in, CAN-SPAM allows unsolicited commercial emails as long as specific rules are followed.

Every commercial email must include the following:

• A clear and simple unsubscribe mechanism that processes requests within 10 business days.
• Accurate subject lines that honestly reflect the content and are not misleading.
• A physical mailing address, which can be a street address, registered P.O. box, or mailbox at a commercial mail receiving agency.
• Identification as an advertisement, when applicable.

These straightforward requirements make CAN-SPAM compliance relatively easy compared to GDPR’s broader, principle-driven framework. This clarity is essential for understanding the financial risks tied to non-compliance, which are explored in the next section.

CAN-SPAM Penalties and Enforcement

Beyond understanding the rules, it’s crucial to grasp the financial and regulatory consequences of failing to comply. Violations of CAN-SPAM can lead to fines ranging from $43,280 to $50,120 per non-compliant email. Since these penalties apply to each individual email, a campaign sent to, say, 10,000 recipients could rack up fines in the hundreds of millions of dollars.

Enforcement is handled by the Federal Trade Commission (FTC), state attorneys general, and Internet Service Providers (ISPs). It’s worth noting that individuals cannot sue for violations - only these authorized entities can take action.

To highlight the importance of compliance, consider Rogers Media’s experience under Canada’s CASL regulation. The company faced a $200,000 fine for failing to maintain a working unsubscribe option. While this example is from a different regulatory framework, it underscores the risks of neglecting key compliance measures.

For businesses managing their own email systems, compliance goes beyond simply adding an unsubscribe link. It involves ensuring that opt-out requests are processed automatically, maintaining accurate sender information, and properly configuring email authentication protocols like SPF, DMARC, and DKIM. These steps not only help meet regulatory requirements but also improve email deliverability.

Some critics have nicknamed CAN-SPAM "You-Can-Spam" to highlight its opt-out approach, suggesting it offers businesses more flexibility while still safeguarding consumer choice. This balance reflects the U.S. preference for business-friendly regulation paired with basic consumer protections.

GDPR vs. CAN-SPAM: Main Differences

GDPR and CAN-SPAM represent two fundamentally different approaches to regulating email marketing and protecting consumers. While they share the goal of shielding recipients from unwanted emails, their methods diverge significantly. Understanding these differences is crucial for businesses aiming to create compliant email practices.

Consent Requirements: Opt-In vs. Opt-Out

One of the most striking differences between GDPR and CAN-SPAM lies in their consent models. GDPR mandates an opt-in approach, requiring businesses to secure explicit, clear, and documented consent before sending marketing emails. This means users must actively agree - typically through actions like double opt-in forms - before being added to any email list.

On the other hand, CAN-SPAM uses an opt-out model, allowing businesses to send unsolicited emails as long as they include a functional and easy-to-use unsubscribe option. The burden under CAN-SPAM is on the recipient to opt out, whereas GDPR places the responsibility on the sender to prove consent.

For example, GDPR prohibits the use of pre-checked boxes on web forms, requiring users to actively select their preferences. CAN-SPAM, however, permits pre-checked boxes in certain cases. This difference underscores the contrasting priorities: GDPR focuses on safeguarding individual privacy and data rights, while CAN-SPAM emphasizes transparency and giving recipients the ability to opt out easily.

Geographic Reach and Applicability

The geographic scope of these regulations adds another layer of complexity, especially for businesses operating internationally. CAN-SPAM applies to any commercial email sent to consumers in the United States, regardless of where the sender is located. Meanwhile, GDPR extends to any organization worldwide that processes the personal data of EU citizens. This means even companies outside Europe must comply if they target EU residents with marketing emails.

For businesses with a global audience, this dual compliance requirement can be challenging. Emails sent to EU recipients must meet GDPR’s stricter standards, while those sent to U.S. recipients must align with CAN-SPAM. Additionally, enforcement differs: GDPR allows individuals to sue companies for damages if their rights are violated, while CAN-SPAM enforcement is limited to actions by the Federal Trade Commission (FTC), state attorneys general, and Internet Service Providers (ISPs).

Side-by-Side Comparison Table

Penalties and Broader Implications

The penalty structures for these regulations highlight their differing priorities. CAN-SPAM fines are calculated per email violation, with penalties ranging from $43,280 to $50,000 per email. For example, a campaign sent to 10,000 recipients could result in fines exceeding $500 million.

GDPR takes a different approach, imposing penalties based on a company’s global revenue. Fines can reach up to €20 million or 4% of annual global turnover, whichever is higher. For a business generating $1 billion annually, this could mean fines of up to $40 million for a single violation.

Beyond financial penalties, GDPR grants individuals far more rights than CAN-SPAM. Under GDPR, individuals can request access to all personal data a company holds about them, demand corrections, or request deletion of their data. Companies are obligated to comply promptly. In contrast, CAN-SPAM focuses narrowly on ensuring recipients can unsubscribe from future emails, offering no broader rights for data access or deletion.

Scope Beyond Email

The scope of GDPR extends far beyond email marketing. It encompasses all forms of personal data processing, including text messages, social media communications, cookies, and analytics. CAN-SPAM, however, is narrowly focused on regulating commercial emails and preventing deceptive practices in email marketing.

For businesses subject to GDPR, compliance must cover the entire digital ecosystem - not just email campaigns. A company could meet CAN-SPAM requirements for its emails but still violate GDPR by improperly collecting data through website cookies or social media ads.

These differences emphasize the need for a well-rounded compliance strategy, especially for businesses operating across multiple jurisdictions.

How to Comply with Both Regulations

Navigating the differences between GDPR and CAN-SPAM can be tricky, but a unified approach can help ensure your email campaigns meet the requirements of both regulations.

Compliance Strategies for Multiple Jurisdictions

One way to simplify compliance is to adopt GDPR's stricter opt-in requirements across all your campaigns. GDPR requires explicit consent before sending marketing emails, while CAN-SPAM focuses on providing an opt-out option. By setting the higher standard of GDPR as your baseline, you can streamline your processes and ensure compliance in all jurisdictions.

This approach also reduces the risk of accidentally sending emails that meet only CAN-SPAM standards to recipients in the EU, which could lead to GDPR violations. It's worth noting that GDPR allows private individuals to sue for damages, a provision not included in CAN-SPAM.

Steps to Implement Email Compliance

Creating a compliant email program involves both technical configurations and operational best practices:

Set up proper email authentication protocols.
Use SPF, DKIM, and DMARC to authorize your mail servers and validate email authenticity. These protocols are essential for ensuring secure and transparent communication.

Design compliant email templates and unsubscribe options.
Your emails should include your business address, a clear unsubscribe link, and details about how you process data. CAN-SPAM requires opt-out requests to be processed within 10 business days, while GDPR mandates that recipients can withdraw consent anytime without hurdles. To meet these standards:

• Offer a one-click unsubscribe option.
• Support multiple opt-out methods, like email or web forms.
• Process opt-out requests within 24–48 hours.
• Maintain a suppression list to avoid sending emails to those who've opted out.
• Provide a preference center so recipients can choose the type of emails they want to receive.

Document consent properly.
Under GDPR, you need to keep proof of consent for each recipient before sending marketing emails. This could include signed forms, email confirmations, or even audio recordings. While CAN-SPAM doesn't require prior consent, maintaining records of opt-out mechanisms and honoring them ensures compliance.

Conduct regular compliance audits.
Compliance isn't a one-time task. Regularly audit your email lists to confirm valid consent, review your email templates, and monitor bounce and complaint rates. Document all consent changes and opt-out requests. Additionally, train your staff and review vendors to ensure everyone involved in your campaigns adheres to the latest regulations.

Differentiate between email types.
Both GDPR and CAN-SPAM distinguish between transactional and marketing emails. Transactional emails, like order confirmations or password resets, don’t require marketing consent since they’re service-related. Marketing emails, however, require explicit opt-in consent under GDPR.

Once these operational measures are in place, the right email infrastructure becomes the final step to ensure smooth compliance.

Conclusion

GDPR and CAN-SPAM take two distinct approaches to email regulation. GDPR prioritizes individual privacy and data rights with its strict opt-in requirements, while CAN-SPAM focuses on transparency and providing recipients with clear opt-out options. Understanding these differences goes beyond avoiding fines - it’s about creating an email marketing strategy that respects your audience and builds trust.

The financial risks are no small matter. Violating CAN-SPAM can result in penalties of up to $43,792 per email, meaning a single campaign could lead to millions in fines. GDPR violations are even steeper, with penalties reaching up to €20 million or 4% of annual global revenue, whichever is higher.

For businesses operating across borders, adopting GDPR's stricter opt-in standards as a universal practice can simplify compliance. This approach minimizes the risk of accidentally breaching GDPR when contacting EU recipients and fosters trust with your audience. While CAN-SPAM permits a send-first, opt-out model, using a permission-based framework can improve engagement and strengthen your relationship with subscribers over time.

On the technical side, maintaining compliance requires a strong infrastructure. Tools like SPF, DMARC, and DKIM are critical for both GDPR and CAN-SPAM. Your email system should also automatically manage unsubscribe requests, track consent records, and prevent emails from being sent to opted-out addresses. Platforms like Mailforge can streamline these processes with automated DNS setup and bulk management tools, reducing the chance of configuration mistakes that could lead to non-compliance.

Compliance isn’t a one-and-done task. As regulations evolve, your email practices need regular reviews. Train your team on the nuances of both laws, establish clear processes for managing consent, and keep a close eye on third-party vendors to ensure they follow the rules.

FAQs

What’s the best way for businesses to comply with both GDPR and CAN-SPAM when sending marketing emails globally?

To navigate the rules of GDPR and CAN-SPAM when sending marketing emails globally, businesses must carefully adhere to the specific guidelines of each regulation. The GDPR, which applies to individuals in the European Economic Area, requires obtaining explicit consent for data processing and providing clear details about how personal data will be used. Meanwhile, the CAN-SPAM Act, which governs email marketing in the United States, requires that commercial emails include a valid physical address, offer a simple way to opt out, and use honest subject lines.

Tools like Mailforge can make compliance easier by offering features such as automated DNS setup, domain masking, and enhanced deliverability options to help ensure your emails align with these regulations. For streamlining workflows, businesses can also leverage tools like Salesforge to manage email sequences, Leadsforge to create targeted lead lists, and Warmforge to improve email deliverability.

What risks do businesses face if they fail to comply with GDPR or CAN-SPAM regulations?

Failing to follow GDPR or CAN-SPAM regulations can have serious repercussions for businesses. Under GDPR, non-compliance can lead to fines as high as €20 million or 4% of a company’s annual global turnover - whichever is greater. Beyond the financial hit, companies risk tarnishing their reputation and facing legal claims from impacted individuals.

For violations of the CAN-SPAM Act in the United States, penalties can amount to $50,120 per email. On top of that, businesses may face lawsuits and see their email deliverability rates take a nosedive. But the risks don’t end there - ignoring these regulations can also break customer trust and strain long-term relationships. Staying compliant isn’t just about avoiding fines; it’s about protecting your business’s credibility and fostering lasting trust with your audience.

Why should businesses follow GDPR's stricter opt-in rules, even in regions where only CAN-SPAM applies?

Adopting the stricter opt-in requirements outlined by GDPR across the board can be a savvy strategy for businesses. Why? It not only helps maintain higher compliance standards but also strengthens trust with your audience. Unlike CAN-SPAM, which permits an opt-out approach, GDPR insists on explicit, informed consent before sending marketing emails. This upfront method minimizes the risk of running afoul of regulations in different regions and shows a clear commitment to respecting user privacy.
