Email scraping, the practice of extracting email addresses from websites or online platforms, often seems like a quick way to build a mailing list. However, engaging in this practice, especially without proper consent and in disregard of regulations like the CAN-SPAM Act, carries significant legal, reputational, and technical risks. It can lead to severe penalties, deliverability issues, and a ruined sender reputation.
Key findings
Legal risks: Violating the CAN-SPAM Act can result in substantial fines, potentially tens of thousands of dollars per non-compliant email. Other regulations like GDPR (if applicable) also pose risks for non-consensual data collection.
Deliverability damage: Sending emails to scraped lists often leads to high bounce rates and spam complaints, which severely harms your sender reputation and causes your emails to land in the spam folder or be blocked entirely. This can lead to your domain or IP being blacklisted.
Spam traps: Scraped lists are highly likely to contain spam traps, email addresses specifically set up by ISPs and anti-spam organizations to catch spammers. Hitting these instantly damages your reputation.
Brand reputation: Consistently sending unsolicited emails leads to negative perceptions of your brand and can cause significant long-term damage to your business's credibility.
Key considerations
Consent is crucial: Always obtain explicit consent before adding individuals to your email list. This is the cornerstone of ethical and effective email marketing.
List hygiene: Regularly clean your email lists to remove inactive or invalid addresses, reducing bounce rates and spam trap hits.
Transparency: Provide clear unsubscribe options in every email and honor opt-out requests promptly.
Authenticity: Ensure your email content is relevant, truthful, and clearly identifies the sender. Avoid misleading subject lines or deceptive practices.
What email marketers say
Many email marketers often seek shortcuts to expand their reach, sometimes leading them to consider practices like email scraping. However, the community frequently shares cautionary tales and strong opinions on why such methods are counterproductive and damaging to long-term marketing success and overall email deliverability. There's a common thread of frustration with those who engage in these practices, as it negatively impacts the email ecosystem for everyone.
Key opinions
Quick path to blacklisting: Marketers quickly learn that scraping emails invariably leads to their domain being blacklisted by various anti-spam organizations, making future legitimate email campaigns impossible.
Low ROI: The general consensus is that campaigns to scraped lists yield abysmal results, with reported open rates as low as 0.8%, demonstrating a clear lack of engagement and return on effort.
Misinterpretation of CAN-SPAM: Some marketers mistakenly believe that the CAN-SPAM Act is solely an 'opt-out' law, not requiring prior consent, leading them to believe sending unsolicited emails is permissible as long as an unsubscribe option is provided.
Spam trap exposure: Using unverified, scraped lists significantly increases the risk of hitting spam traps, which are designed to identify and penalize senders of unsolicited bulk email. Understanding how spam traps work is key.
Ethical concerns: There's a strong sentiment that such practices are unethical and damage the credibility of the entire email marketing profession, highlighting the importance of building lists legitimately.
Key considerations
Embrace legitimate list building: Focus on organic list growth through opt-in forms, lead magnets, and valuable content to ensure engaged subscribers.
Educate on compliance: Ensure a thorough understanding of email marketing regulations like CAN-SPAM, prioritizing consent over mere unsubscribe options.
Monitor domain health: Regularly check your domain's reputation to identify any potential blacklisting issues early.
Quality over quantity: Prioritize building a smaller, highly engaged list over a large, unconsented one for better deliverability and campaign performance.

What the experts say
Deliverability experts consistently warn against email scraping and non-compliance with regulations like the CAN-SPAM Act. Their insights often focus on the severe, long-lasting repercussions for sender reputation and the overall email ecosystem. They emphasize that while some practices might offer short-term gains, the long-term damage far outweighs any perceived benefit. Experts also highlight the subtle ways these actions erode trust and lead to deliverability failures.
Key opinions
Reputation is paramount: Experts agree that sending to unconsented, scraped lists is a direct attack on your sender reputation, which is painstakingly built over time and easily destroyed by such practices. This damage extends beyond immediate campaigns.
Spam trap activation: Using scraped lists almost guarantees hitting spam traps, which are designed to identify and penalize senders of unsolicited bulk email. Each hit significantly impacts your sender score.
Zero-tolerance policies: Many ISPs and email service providers (ESPs) have zero-tolerance policies for unsolicited email, leading to immediate blocking, account suspension, or even permanent bans. This impacts not just your current campaign but your ability to send email from that platform in the future.
Legal ramifications: While CAN-SPAM is often misunderstood, experts emphasize its serious financial penalties. They caution that ignorance of the law is not a defense, and fines can accumulate rapidly per offending email.
Ecosystem integrity: Unethical scraping practices negatively affect the entire email ecosystem, contributing to spam filters becoming more aggressive and making it harder for legitimate marketers to reach the inbox.
Key considerations
Proactive list cleaning: Implement robust email validation and list hygiene practices to minimize invalid addresses and reduce the risk of hitting spam traps. This also includes preventing bot sign-ups.
Understand email authentication: Ensure your email sending infrastructure is properly configured with SPF, DKIM, and DMARC to build trust with receiving servers. Learn about a simple guide to DMARC, SPF, and DKIM.
Prioritize permission-based marketing: Focus exclusively on building opt-in lists. This ensures higher engagement, better deliverability, and compliance with regulations.

They serve as authoritative sources for understanding the risks and requirements.
Key findings
CAN-SPAM Act penalties: The Federal Trade Commission (FTC) explicitly states that each separate email in violation of the CAN-SPAM Act can incur penalties of up to $53,088. This applies to bulk unsolicited commercial email.
Definition of commercial email: Commercial email is defined by its primary purpose, which includes promoting a product, service, or commercial content, irrespective of whether the sender has a prior relationship with the recipient.
Mandatory unsubscribe mechanism: All commercial emails must include a clear and conspicuous way for recipients to opt out of receiving future emails, and opt-out requests must be honored promptly (within 10 business days).
Accurate sender information: Commercial emails must include a valid physical postal address and accurate header information that clearly identifies the sender.
Consequences for non-compliance: Beyond fines, non-compliance can lead to civil lawsuits, criminal charges in severe cases, and negative impacts on sender reputation, including placement on blocklists, which are detailed in guides like what happens when your domain is blacklisted.
Key considerations
Adherence to CAN-SPAM: Businesses should strictly adhere to all seven key requirements of the CAN-SPAM Act, particularly regarding accurate headers, clear subject lines, and valid opt-out mechanisms.
Consent vs. opt-out: While CAN-SPAM is often called an opt-out law, best practices and international regulations like GDPR strongly favor explicit consent (opt-in) for email marketing.
Email authentication: Implement robust email authentication protocols such as SPF, DKIM, and DMARC to prove sender legitimacy and improve deliverability.
Monitor deliverability metrics: Pay close attention to bounce rates, complaint rates, and inbox placement to detect and address issues proactively.
