Key Findings
- 01A comprehensive catalog of 42 distinct email-based deception techniques has been identified.
- 02These techniques exploit sender, link, and attachment security indicators, as well as the email rendering environment.
- 03Each technique's underlying mechanism is explained in isolation, separating the goal from the implementation.
Application
Design takeaway
Rethink fundamental email interface elements to proactively mitigate deceptive practices, rather than solely relying on user vigilance.
How to apply
Use the documented techniques as a checklist to audit existing email clients and communication platforms for potential vulnerabilities, and to inform the design of new, more secure interfaces.
Project actions
- 01When designing a communication tool, consider how its features could be twisted to deceive users.
- 02Research common phishing or scam techniques and analyze how the interface of the communication platform enables them.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a comprehensive and structured catalog of deception techniques.
- +Distinguishes between the goal of deception and its technical implementation.
Limitations
The study does not quantify the impact of each technique or provide solutions, but rather catalogues the problems.
Reliability & validity
The reliability of the catalog depends on the thoroughness of the literature review and expert examination. Validity is supported by the detailed examples and categorization, but real-world effectiveness is not assessed.
Think critically
To what extent is the responsibility for email security a design problem versus a user education problem, and how can design interventions effectively address the identified deception techniques?
Design Principles
"Design communication interfaces with an inherent bias towards clarity and security, anticipating potential misuse of standard features."
Understanding how interface elements and established email practices can be exploited is crucial for designing more secure and trustworthy communication systems. This knowledge allows for targeted interventions in both technical infrastructure and user education.
What This Means for Your Design
The way emails are designed can make it easier for bad actors to trick people, not just because people aren't careful, but because the email system itself has features that can be misused.

Paragraph starter
This research by Veit et al. (2026) provides a foundational understanding of how email interface conventions can be exploited for user deception, cataloguing 42 distinct techniques. This highlights the critical need for designers to consider the security implications of their interface choices, as standard design elements can inadvertently become vectors for malicious attacks.
