Essilor increases sales with SMS coupon campaign.

Essilor, a global leader in corrective lenses and instruments for ophthalmologists and opticians, faced the challenge of increasing sales across various stores in France. Previously, Essilor had encountered significant fraud with discount promotions. They needed a new, secure approach to address this issue while also enhancing customer engagement.

How we addressed and solved the problem:

Essilor turned to Coupontools for an advanced SMS coupon campaign. Coupontools designed two variants of the coupon, as Essilor wanted to distribute the coupons through two channels: SMS and WhatsApp. This allowed Essilor to determine which channel customers preferred for receiving the coupon. Thanks to a CRM integration, accessible to each store, cashiers could securely validate the coupons. Unique validation codes were embedded in the coupons, and an intelligent API call verified the validity of the code. Once the code was validated, the coupon could not be reused..

Campaign setup:

Essilor promoted the coupons through posters in various stores. Store visitors could participate in two ways:

By sending an SMS message to a shortcode, they received a message with the URL of the digital coupon.

By scanning a QR code, WhatsApp was automatically opened with a predefined message ready to send. After sending this message, they received the coupon URL.

This method gave Essilor control over who received which and how many coupons. Each phone number that sent a message received a unique coupon. Once redeemed, the coupon could not be reused. If someone tried to send a second message to the shortcode or via WhatsApp, they received the same coupon again. Both methods were connected to the same database to check if the person had already received a coupon. By integrating unique validation codes and an API call, fraud was eliminated. Essilor ensured that each phone number was entitled to only one coupon, which could only be used once. To increase conversion, Essilor sent a reminder message one month before the coupon's expiration to those who had not yet redeemed the coupon.

What the customer achieved with our solution:

Thanks to this campaign, Essilor was able to completely eliminate fraud while simultaneously collecting valuable customer data. The campaign resulted in a significant increase in sales and provided valuable statistics. Essilor knew exactly how many people participated, how many coupons were redeemed, and which store was responsible for the most validations. This provided Essilor with better insights into customer behavior and store performance.
