Summary
The scarcity of spam court cases stems from several factors, including the challenges of prosecuting cross-border spammers who conceal their identities and the initial limitations of CAN-SPAM, such as low fines and weak enforcement. State laws and regulations like GDPR have emerged to address these shortcomings by setting opt-in requirements and stronger enforcement mechanisms. However, the fundamental issue remains the lack of financial incentives to actively stop spammers. Various organizations and frameworks, like Spamhaus, Talos Intelligence, NIST, and M3AAWG, offer solutions through blocklists, threat intelligence, cybersecurity guidelines, and best practices. Email authentication protocols, sophisticated spam filters, and reputation monitoring are crucial but require constant adaptation due to evolving spammer tactics. International cooperation is vital but hindered by differing legal frameworks. Email addresses are now considered PII, prompting new privacy regulations.
Key findings
- Prosecution Difficulties: Cross-border spammers conceal identities, making prosecution costly and complex.
- CAN-SPAM Limitations: Low fines and weak enforcement initially limited CAN-SPAM's effectiveness.
- State & GDPR Solutions: State laws and GDPR set opt-in requirements and stricter enforcement.
- Financial Disincentive: Lack of financial incentive to stop spammers; more profit in email services.
- Organizational Efforts: Spamhaus, Talos, NIST, and M3AAWG offer blocklists, intelligence, and guidelines.
- Evolving Tactics: Spammers constantly adapt, necessitating continuous updates to defenses.
- PII Classification: Email addresses are now PII, leading to stricter privacy regulations.
Key considerations
- International Law: International cooperation is crucial but faces challenges in differing legal systems.
- Burden of Proof: High burden of proof hinders enforcement; cases often dismissed.
- Reputation Monitoring: Monitor sender reputation and blacklisting to maintain deliverability.
- Financial Incentives: Need stronger financial incentives to combat spam effectively.
- Proactive Strategies: Proactive measures like threat intelligence and filters are essential.
What email marketers say
12 marketer opinions
The limited number of spam court cases is attributed to various factors, including the difficulty of prosecuting spammers due to their cross-border operations and the use of sophisticated techniques to hide their identities. CAN-SPAM's initial shortcomings, such as low fines and weak enforcement, have been partially addressed by state laws and international efforts like GDPR. Email authentication protocols (SPF, DKIM, DMARC) and sophisticated spam filters play a crucial role in reducing spam, while ongoing challenges include international cooperation and the constant adaptation of spammers' tactics. The classification of email addresses as PII is also leading to new privacy regulations impacting spam.
Key opinions
- Prosecution Challenges: Spammers often operate across borders, using botnets and spoofed email addresses, making prosecution expensive and complicated. Proving their identity and location is a major hurdle.
- CAN-SPAM Limitations: CAN-SPAM's initial fines were too low, and enforcement is difficult internationally, leading to its limited effectiveness in stopping spam.
- GDPR Impact: GDPR aims to reduce spam by requiring explicit consent and imposing hefty fines, making spamming riskier.
- Email Authentication: Email authentication protocols (SPF, DKIM, DMARC) help verify senders and reduce spam, improving deliverability.
- Spam Filter Sophistication: Spam filters use machine learning to identify and block spam, but spammers constantly adapt, creating an ongoing challenge.
- State Laws & PII: The classification of email addresses as PII is leading to new privacy regulations that impact spam and data handling.
Key considerations
- International Cooperation: Effective international cooperation is crucial for combating spam, but differing legal frameworks can pose challenges.
- Burden of Proof: Enforcing anti-spam laws is difficult due to the high burden of proof required to identify and prosecute spammers.
- Reputation Monitoring: Regularly monitor sender reputation and IP address for blacklisting to maintain email deliverability.
- Evolving Tactics: Spammers continuously adapt their techniques, requiring constant updates to spam filters and anti-spam measures.
- Legal Loopholes: Spam was not technically illegal in the U.S. until state laws were passed, highlighting the influence of marketing lobbies on federal legislation.

Marketer view
Marketer from Email Geeks explains that spam was not technically illegal in the U.S. until state laws were passed because marketing lobbies influenced CAN-SPAM drafting. State laws fill the void, leading to a confusing patchwork, which may eventually lead to a federal law.

What the experts say
3 expert opinions
The limited number of spam court cases is attributed to multiple factors. Firstly, opt-in requirements are evolving via privacy laws as a workaround because CAN-SPAM supersedes other email regulations. Secondly, there's a lack of financial incentive to actively stop spammers, as the focus is more on selling email sending services. Finally, spammers effectively conceal their origins, often operating from various networks and foreign countries, making legal pursuit difficult and costly.
Key opinions
- CAN-SPAM Workaround: Opt-in requirements are emerging through privacy laws to circumvent CAN-SPAM's broad reach.
- Lack of Financial Incentive: There is little financial motivation to stop spammers, as most of the money is in facilitating email sending, not preventing spam.
- Spammer Concealment: Spammers are adept at hiding their origin, often operating from multiple networks and foreign countries, hindering legal enforcement.
Key considerations
- Privacy Law Evolution: The rise of opt-in requirements suggests that privacy laws are increasingly used to regulate email marketing practices where CAN-SPAM falls short.
- Economic Disincentives: The absence of a strong economic incentive to combat spam undermines efforts to enforce anti-spam laws.
- Jurisdictional Challenges: International spammers present significant jurisdictional challenges, making legal action both difficult and expensive.

Expert view
Expert from Word to the Wise shares that one of the big problems of enforcing anti-spam laws is that spammers are good at hiding where the spam is coming from. They can hop from network to network, making it very difficult to track them down. Often, these spammers are based in other countries which makes it harder and more expensive to legally pursue them.
