What is coupon misuse?
Coupon fraud happens when an individual intentionally takes advantage of a coupon offer by using a coupon they are not eligible for, redeeming the coupon multiple times, or using coupons in other ways for monetary gain. Businesses worldwide use coupons to attract and engage potential customers; however, they find it increasingly challenging to target and control coupon usage. Coupon fraud is a threat to both business and customers who may be wrongly accused of coupon fraud or pay more due to retailers trying to mitigate the losses that stem from abuse.
As digital coupon fraud becomes increasingly sophisticated, you need to take proper anti-fraud measures to face non-stop bugs exploitation, poor programming, and password cracking software.
How to combat coupon fraud and abuse?
Adequate limits on coupon usage translate into a more accurate ROI and more conversions. By implementing the following tips to your coupon strategy, you can eliminate misuses that misshape campaign metrics and burn your promotional budget.
1. Generate hard-to-crack codes
First things first. You could have implemented the most sophisticated back-end anti-fraud measures but still fail to protect your coupon codes effectively. If you release coupon codes in the form of a firm prefix and two random characters (e.g., THANKU##), the chances of customers guessing the codes are pretty high. Randomly generated codes with an approximate length of 8-12 characters should be unguessable and unique enough.
Let’s take an 8-character long string with 63 possible characters. That gives us 248 155 780 267 521 possible codes (63^8). With random codes, the chances of customers taking an educated guess at the code combination are scant.
2. Limit the number of coupon redemptions
Whether you run a fixed-code campaign or a campaign of unique coupons, you should set the total number of code redemptions according to your goals:
- Coupons can be redeemed only once.
- Coupons can be redeemed X number of times.
- Coupon redemptions are unlimited (not recommended).
The most popular marketing strategy limits voucher usage to once per customer. This practice is common, especially in companies that use public, fixed-code campaigns. The once-per-customer rule is useful in campaigns tuned toward acquiring new customers. After a valid order, you can be sure that a new client won’t use the code again. Other benefits appear while running A/B tests.
By placing a cap on the total number of redemptions, you ensure that the promotion won’t kill your stock. You can also use it to increase users’ engagement by running promotions similar to: “$20 off for the first 200 shoppers with the code ACME2017.”
3. Control the coupon activity period
The more attractive the incentive and the longer the activity period, the bigger the chances of attracting fraudsters. Your coupon campaigns should have firm time limits, such as start and end date. You can also introduce more time-specific limitations that would make the code redemption even more restrictive. Your coupon campaigns should always end automatically without any intervention needed from your development team to prevent campaign overspending.
4. Assign unique codes to single customer profiles
If you intend to run a coupon marketing campaign with unique coupon codes, you should first individualize them (assign them to individual customers). By attaching discount codes to customer profiles, you get better control over how your promotions play out and quickly target codes at the most valuable customers, especially those with the highest CLV rates. This way, only selected customers can redeem the given bulk of codes, protecting your coupon campaign from fraud attempts.
5. Introduce budgetary limits
There are multiple ways to guard yourself against exceeding the campaign budget. Here are some of them:
- Limited total number of discount codes that can be generated and redeemed within a single campaign.
- Limited total value of orders made with a particular coupon batch.
- Limited total value of redeemed discounts per campaign or order.
This can be based on either the overall campaign budget you have or, more specifically, a limit on the total amount of coupon discounts you give. You can also introduce restrictions on the total discount value. For instance, you can decide that the maximum discount value is 50$, nevertheless the original order amount and discount value.
6. Use cart- and order-based coupon redemption criteria
Thanks to cart- and order-based limits, you can allow discounts only when the cart value gives a beneficial balance between promotion costs and profits. Moreover, with a minimum amount spent and product-based rules, you can inscribe up-selling and cross-selling into your coupon strategy and maximize your customers’ buying potential. You can use multiple such limitations to make sure that only desired orders can be discounted:
- The order has to include/exclude selected products.
- The minimum/maximum order value.
- Required minimum/maximum price of all/different products in the cart.
- The minimum number of purchased items.
- Discount applicable only to selected products/SKUs, not whole orders.
7. Introduce email verification for digital offers
Unfortunately, some customers will seek creative ways to attempt fraud. Often, these customers register themselves using different email addresses to take advantage of your digital promotions. Here is what you can do to protect your incentives from email coupon fraud:
- Double opt-in
The double opt-in feature is used to verify the email address of your customers. By sending them a verification email before finishing registration, it is possible to check if the address exists in the first place. Verifying customers’ email addresses will help you combat fraud attempts and fake email addresses.
- Block email aliases
An email alias is an additional name for an email account. Fraudsters often use aliases to sign up for loyalty or referral programs to use your incentives multiple times. You should automatically block email aliases from receiving coupon codes and other promotional messages.
- Request unique email addresses
You should block users from taking advantage of your incentives by using the same email address over and over again. Your promotion engine should automatically remember and store all the email addresses to prevent users from creating duplicates. To make this measure more effective, you should also not forget about lowercasing email addresses so that these two email addresses are recognized as the same, a not unique – JeNNa@voucherify.io and JENNa@voucherify.io.
8. Invest in behavioral analytics to detect suspicious activity
I am sure that I don’t have to explain what Google Analytics is and how helpful it can be for tracking what is going on in your store. Behavioral analytics delivered by Google Analytics, Woopra, or other analytics tools should tell you a story of customer activity. How does it translate into more secure coupon campaigns? Well, for instance, you can track which customer started referring friends or abandoning orders right after account creation (without even browsing the store) as real shoppers tend to shop around a lot longer. After the suspicious behavior is detected, you can block the user account and reach out to them to verify their identity and intentions.
9. Monitor IP addresses with a web beacon
Many companies offer special sign-up incentives dedicated to new customers only. Welcome coupons are a great way to increase your conversion rates; however, they also attract fraudsters who will open many accounts to receive the discount multiple times. Luckily, you can block these accounts from being opened by placing a web beacon on your site. A web beacon is a code snippet from Google that transmits data from your site into your Google Analytics account. With the help of a web beacon, you can check the device and the IP address of customers attempting to register and successfully block any fraudulent activity.
10. Create geo-located coupons
Geolocation lets you tailor your coupon marketing strategy to a target location. It is not only a fantastic tool for delivering more accurate and timely incentives but also a creative way to secure redemptions. The catch is to monitor customer data and verify their location once the redemption takes place. Such a workflow can be managed with an efficient flow of data between your CRM and promotion software. You can easily create coupon codes limited to the specific country, city, or postal code to track if and where your coupon codes are the most popular.
11. Monitor redemptions to detect suspicious behavior
It’s done – you have released a coupon campaign out into the wild. Now, you might be wondering if your campaign is doing fine. Use a promotion software with a dedicated analytics view to see all campaigns redemption rates to compare them at a glance. By doing so, you’ll quickly figure out the critical parameters of your successful campaigns, and you’ll be able to fine-tune future campaigns.
If you are worried about monitoring failed redemptions that may indicate a fraud attempt, you can connect your redemption gateway to a webhook. Webhooks will transmit the notification about a failed redemption directly to your marketing team (on Slack, email, or another tool). You can use Zapier to model such marketing automation with Voucherify Promotion Engine.
12. Control the coupon distribution
If you decide to run an open-for-all coupon campaign, you need to be mindful of the coupon distribution process. Whether it’s an email marketing campaign or a quick text message, you always need to make sure that each coupon code is assigned to a specific marketing channel to track coupon ROI per channel easily.
Are you publishing multiple coupon campaigns on coupon-aggregating websites? Monitoring your campaigns in such a complex distribution model can be frustrating and inefficient, to say the least. The key is to regularly check if they stick to the promotion guidelines, e.g., if the deal is displayed at the right time and place. Other things to consider when partnering up with coupon aggregate websites include:
- Use a separate coupon campaign for each partner/distribution channel to figure out the attribution right away.
- Create separate redemption gateways to isolate coupon redemptions coming from different sources.
- Manage the lifecycle of your coupon codes by viewing the details of each coupon code.
13. Use a staging environment to test coupons
Make sure that your coupon provider offers a sandbox mode where you can test your campaign before release. You can also start by releasing small-scale incentives (e.g., for a particular location or store only) to check your coupon for any potential weakness without risking burning the whole promotional budget on the first campaign.
14. Control access to your promotion software
I don’t want to feed the paranoia, but the security of your coupon offers can be undermined from the inside. Suppose your promotion management software is open-for-all, and credentials to it are available for many of your employees. In that case, you run a risk of employees generating reusable discount codes for their personal use.
You should always ask the fundamental question – who should have access to the promotion engine, what should individual users see, and what types of actions can they take.
15. Don’t reveal everything
It goes without saying that your promotion terms and conditions should be transparent and easy to understand. However, by fully disclosing your coupon codes limitations and restrictions, you open up a loophole for abusers to leverage. For instance, you don’t have to disclose the information that a cart-abandoned offer applies to all carts abandoned. To limit the potential of fraud, you can state that cart abandoned offers will be available only for the first purchase, and not existing customers.
As you can clearly see, there are multiple techniques you can implement to combat coupon fraud and abuse effectively. Sadly, developers are often bombarded with too many requests and unable to manage the coupon campaign and the core product. The best solution is to find a professional promotion management software that will handle all the work for you.
