Summary
Using honeypots in B2B emails to identify and filter out bot clicks while maintaining deliverability involves a comprehensive approach. Several methods are suggested, including embedding nearly invisible links (like commas or 1x1 pixel GIFs), using hidden form fields, and analyzing user behavior for suspicious activity. A/B testing helps optimize these techniques. Maintaining a clean email list through confirmed opt-ins, regular cleaning, and avoiding purchased lists is crucial. Automation can segment users based on their interaction with honeypots. Sender reputation, adherence to SMTP standards (SPF, DKIM, DMARC), and integrating URIBLs are vital for preventing bots and maintaining deliverability.
Key findings
- Honeypot Techniques: Effective honeypot techniques include invisible links, hidden form fields, and behavioral analysis.
- List Hygiene: Maintaining a clean, organically built email list is critical for minimizing bot intrusion.
- A/B Testing Importance: A/B testing is essential for optimizing honeypot effectiveness and minimizing false positives.
- Automation Benefits: Automation enables the segmentation and tagging of users interacting with honeypots.
- Technical Standards: Adhering to SMTP standards (SPF, DKIM, DMARC) significantly improves deliverability.
- External Resources: URIBLs provide a resource for identifying and blocking spam-associated domains.
Key considerations
- Minimizing False Positives: Carefully design honeypots to minimize false positives and avoid penalizing legitimate users.
- Deliverability Impact: Continuously monitor deliverability metrics to ensure honeypots do not negatively impact inbox placement.
- Bot Evolution: Regularly update honeypot techniques to adapt to evolving bot behaviors and tactics.
- User Experience: Ensure that honeypot implementation does not negatively affect the user experience of legitimate subscribers.
- Data Privacy: Implement data privacy measures when handling bot-related data and avoid storing personal information unnecessarily.
What email marketers say
10 marketer opinions
Several strategies can be employed to use honeypots effectively in B2B emails for bot detection without harming deliverability. These include utilizing nearly invisible links (like commas), hidden form fields, or analyzing user behavior such as click speed and email open rates. A/B testing is recommended to determine the most effective methods. Maintaining clean email lists, building them organically with double opt-in, and monitoring sender reputation are also crucial. Automation can tag and segment users interacting with honeypot links for further analysis and reporting. The central theme is to identify and isolate bot activity while ensuring legitimate user engagement remains unaffected, preserving sender reputation and email deliverability.
Key opinions
- Honeypot Types: Various types of honeypots can be used, including invisible links, hidden form fields, and analyzing user behavior.
- A/B Testing: A/B testing is crucial for determining the effectiveness of different honeypot methods.
- Clean Lists: Maintaining a clean email list is essential to reduce bot activity and improve deliverability.
- Automation: Automation can be used to tag and segment users based on their interaction with honeypot links.
- Sender Reputation: Monitoring and maintaining a positive sender reputation is vital for ensuring emails reach the inbox.
Key considerations
- Visibility: Honeypot links should be nearly invisible to humans to avoid accidental clicks.
- Deliverability Impact: Ensure honeypot methods do not negatively impact email deliverability or trigger spam filters.
- Behavior Analysis: User behavior analysis should be used in conjunction with honeypots for more accurate bot detection.
- Organic List Building: Build email lists organically with double opt-in to minimize the risk of bots.
- Regular Monitoring: Regularly monitor email metrics and sender reputation to identify and address potential issues.
Marketer view
Email marketer from Litmus warns against using purchased email lists, as they often contain spam traps and bot addresses. Building your list organically and implementing double opt-in can help prevent bots from entering your subscriber base, reducing the need for extensive honeypot measures.

Email marketer from Neil Patel's Blog suggests using a hidden form field in email signup forms or landing pages as a honeypot. If a bot fills this field, it's identified as spam. This method can be adapted for B2B emails by including a hidden link or form field that legitimate users wouldn't interact with.

What the experts say
3 expert opinions
Using honeypots in B2B emails to identify and filter out bot clicks without impacting deliverability involves a multi-faceted approach. One method employs hidden 1x1 pixel transparent GIFs, tracked to identify bots and place them in a "clickbot jail" for reporting purposes. Another focuses on maintaining clean email lists through confirmed opt-ins and regular list cleaning to avoid spam traps. Additionally, leveraging URIBLs to identify and block clicks from spam-associated domains can enhance filtering efforts. These strategies emphasize proactive bot identification and prevention while safeguarding deliverability.
Key opinions
- Hidden Pixels: Using hidden 1x1 pixel GIFs can effectively identify clickbots without harming deliverability.
- List Hygiene: Maintaining clean email lists with confirmed opt-ins prevents bots and spam traps.
- URIBLs: URIBLs can identify and block bot clicks originating from domains associated with spam.
Key considerations
- Clickbot Jail: Implementing a system to isolate identified clickbots (e.g., a "clickbot jail") for reporting.
- Opt-in Process: Ensuring a confirmed opt-in process to verify subscribers are genuine.
- URIBL Integration: Integrating URIBLs into your email filtering system for enhanced bot detection.
Expert view
Expert from Spam Resource explains URIBLs (Uniform Resource Identifier Blacklists) can act as honeypots by identifying domains and URLs frequently associated with spam. While not directly implemented within an email, they can be integrated into your filtering system to identify and block bot clicks originating from known spam sources.

Expert from Word to the Wise, Laura Atkins, emphasizes the importance of maintaining clean email lists to avoid spam traps, which act as honeypots. She suggests using confirmed opt-in to ensure subscribers are genuine and engaged, reducing the likelihood of bots entering your list. Regular list cleaning by removing inactive subscribers also improves deliverability and reduces the impact of any bot activity.

What the documentation says
5 technical articles
Honeypots are effective for identifying spambots by attracting them with fake links and form fields within B2B emails. These traps are designed to be invisible to humans but easily crawled by bots. Server-side validation is crucial to confirm that honeypot fields remain empty for legitimate users, thereby filtering out bots without affecting genuine engagement. While network-level honeypots offer insights into bot behavior, adhering to SMTP standards, configuring SPF, DKIM, and DMARC records improves deliverability and reduces spam flags.
Key findings
- Attraction: Honeypots attract spambots with fake links and form fields.
- Invisibility: Honeypots are designed to be invisible to human users.
- Server-Side Validation: Server-side validation confirms that honeypot fields remain empty for legitimate users.
- Network Insights: Network-level honeypots provide insights into bot behavior.
- SMTP Standards: Adhering to SMTP standards improves deliverability and reduces spam flags.
Key considerations
- False Positives: Ensure server-side validation accurately identifies bots to avoid false positives.
- Maintenance: Regularly update and maintain honeypot strategies to adapt to evolving bot tactics.
- Configuration: Properly configure SPF, DKIM, and DMARC records to authenticate emails and prevent spoofing.
- Ethical Use: Use honeypots ethically, ensuring they don't create unintended harm or violate privacy.
- Holistic Approach: Combine honeypot strategies with other security measures for a comprehensive approach to spam prevention.
