Why Fraud Prevention Ties Directly to Customer Retention in Edtech

Fraud isn’t just a finance problem—it hits user trust and engagement hard. For a STEM-education company running St. Patrick’s Day promotions, a fraud spike during special offers isn’t rare. Fraudulent accounts redeeming prizes or abusing discounts can drain resources and alienate genuine users. Your job as a UX researcher is to spot where fraud cuts the experience, then help design fixes that keep learners coming back.

A 2024 Forrester report found that 38% of customers who experience fraud stop using a service within three months. That’s churn you cannot afford in an industry centered on sustained learning paths. Let’s dig into 15 straightforward ways to tackle fraud without disrupting the engagement you want.

1. Track Promo Code Abuse with User Behavior Metrics

Promo codes for St. Patrick’s Day can bring a flood of new and returning users. But watch out for patterns that scream fraud: multiple redemptions from the same device or IP, users cashing out multiple accounts, or odd hours of usage.

Set up your analytics to flag:

• Accounts with more than one promo redemption in 24 hours.
• Multiple sign-ins from a single IP address using different emails.
• Usage spikes immediately after promo launch.

Don’t just block suspected users outright. Instead, identify the behavior and plan usability tests or surveys to understand if there are legitimate reasons (e.g., families sharing devices). Use tools like Zigpoll post-promo to gather user feedback on the redemption process.

Gotcha: Auto-blocking can alienate genuine users, especially students in shared learning environments. Balance fraud flags with contextual awareness.

2. Use Email Verification to Confirm Genuine Accounts

If your St. Patrick’s Day promotion requires registration, email verification filters out bots and throwaway accounts. Email confirmation adds friction, but it’s a necessary step to protect your promo resources.

Have a clear, friendly verification flow. Test with real users to avoid drop-off. For example, a STEM-platform ran email verification tests and found a 12% drop in completed sign-ups—but those who verified were 3x more engaged in courses later.

Edge Case: Some schools block emails from unknown domains. Offer alternative verification like phone SMS or single sign-on with Google Classroom accounts.

3. Implement CAPTCHA Only at Key Steps

CAPTCHA can deter bots but overusing it annoys users. Place CAPTCHAs during account creation or promo code entry, but not during every login or quiz submission.

One edtech startup saw a 7% increase in promo redemptions when they switched CAPTCHA to only appear at checkout, not during browsing or lesson access.

Limitation: CAPTCHAs can be inaccessible to some learners with disabilities. Always provide an alternative, like audio CAPTCHA.

4. Monitor Device Fingerprints Over Time

Device fingerprinting tracks unique device traits (browser, OS, screen size) to identify recurring fraud attempts from the same device under multiple accounts.

Tools for this are built into many fraud-detection platforms, but you can collaborate with your data team to track fingerprint patterns over time.

A team running seasonal STEM contest promotions found that 15% of suspected fraud accounts originated from just 5 device fingerprints, leading to targeted blocks before campaigns started.

Note: Device fingerprinting isn’t foolproof; virtual machines and VPNs can mask devices.

5. Design the Promotion to Limit Instantaneous Benefit

Promos that reward instant, high-value prizes attract fraudsters looking for quick gain. Instead, design promotions that reward sustained engagement, like redeeming a badge after completing 3 STEM modules.

This slows down fraudsters who rely on rapid, one-off redemptions without interaction.

Example: A coding platform shifted from instant gift cards to a points system earned over weeks during their March STEM celebration. Fraud dropped 40%, while genuine user engagement rose 25%.

Tradeoff: Longer reward cycles require clear communication to keep users motivated.

6. Set Redemption Limits per User and Device

Simple but effective. Limit promo code redemptions to one per account and device during St. Patrick’s Day sales.

Make sure backend logic enforces these limits strictly. Test edge cases such as:

• Users clearing cookies or using incognito mode.
• Multiple devices per household (family accounts).

Pro Tip: Use server-side checks rather than relying solely on client cookies to prevent easy circumvention.

7. Use Behavioral Surveys Post-Promotion

After the campaign, gather feedback on the redemption experience via surveys. Tools like Zigpoll, SurveyMonkey, and Typeform can provide quick insights into whether users encountered suspicious activity or confusing steps.

You might discover issues that indirectly encourage fraud, such as unclear promo terms or confusing UI flows.

Heads-up: Survey fatigue is real—keep questions concise and incentivize participation subtly.

8. Segment Users to Spot Unusual Groups

Group your customers by behavior, location, and account age. Fraud often clusters in new accounts or specific geographies.

For instance, if you notice a surge in promo redemptions from newly created accounts in a region where you don’t usually operate, that’s a red flag.

UX researchers can help by mapping these segments to personas and checking if suspicious segments match typical users.

Challenge: Legitimate users sometimes cluster in unexpected ways too, like a new school signing up en masse.

9. Collaborate with Customer Support on Fraud Signals

Customer service reps often spot fraud from user complaints—duplicate charges, redemptions not applying, or locked accounts.

Set up a simple feedback loop where support flags suspicious behavior and UX researchers analyze these cases for UI or process weaknesses.

For example, a STEM company discovered that users misunderstood promo code entry when they complained repeatedly, leading to accidental multiple submissions flagged as fraud.

10. Simplify Terms but Make Them Clear

Complex promo terms confuse users, leading them to test workarounds that look like fraud attempts.

Write your St. Patrick’s Day promo terms in plain language with UX-tested clarity. Research shows 60% of users drop out when terms are confusing or ambiguous (2023 Nielsen Norman Group).

Keep a FAQ visible in the promo UI. This reduces accidental misuse and builds trust.

11. Use Two-Factor Authentication (2FA) for High-Value Actions

If your promotion offers prizes like expensive kits or scholarships, adding 2FA during redemption elevates security.

Students and educators can use email or phone-based codes. Because it adds steps, restrict 2FA to significant redemptions only.

A STEM edtech firm added 2FA for scholarship claims, preventing $12K in fraudulent awards within one campaign.

Downside: 2FA can reduce conversion, so measure impact carefully.

12. Test Your Fraud Prevention Features with Real Users

Don’t just build fraud controls in isolation. Run usability tests with students and teachers to ensure fraud prevention features don’t frustrate or confuse them.

You might discover that device fingerprint prompts are seen as invasive or CAPTCHA slows progress.

A UX team working on a robotics platform’s holiday sale cut false fraud flags by 30% after iterating designs based on user feedback.

13. Have a Clear and Fair Fraud Appeal Process

Mistakes happen. Innocent users might get flagged during a St. Patrick’s Day rush.

Set up a straightforward appeal path with quick response guarantees. Communicate the process clearly in your UI and confirmation emails.

This builds trust and loyalty, turning what could be a churn point into a positive interaction.

14. Analyze Fraud Data Collaboratively Across Teams

Fraud prevention isn’t just your problem—it touches product, engineering, support, and marketing.

Share fraud data regularly in cross-team meetings. UX researchers can translate complex metrics into actionable design fixes or communication tweaks.

For example, your marketing team can adjust promo wording to reduce misunderstanding-driven fraud.

15. Prioritize Fraud Prevention Efforts Based on Impact and Effort

Not all fraud prevention tactics are equal. Start by focusing on:

• Email verification and redemption limits (high impact, low effort)
• Behavioral surveys for ongoing insights
• Collaboration with support for real-world signals

Then move on to device fingerprinting and 2FA, which require more technical setup.

Keep measuring user retention before and after deploying changes to confirm positive effects.
