Use case: SMS coupon campagne voor Essilor: maximale impact met één bericht

The French multinational Essilor, a global leader in corrective lenses and instruments for eye doctors and opticians, wanted to give sales in its stores across France a significant boost. Together with Smstools, they launched a striking and highly effective SMS coupon campaign.

The campaign was simple yet powerful: potential customers saw posters in stores inviting them to send an SMS to a special shortcode. Once sent, they immediately received a link to their personal coupon, including a unique code. One SMS, one coupon, one chance to redeem – per unique phone number.

Why SMS instead of email? Essilor had previously faced fraud in digital campaigns. By using a unique mobile code, this issue was cleverly avoided. Tried to claim a coupon multiple times? The user simply received the same coupon again. Using SMS ensured fraud was prevented and each coupon was truly claimed by a unique person.

To further boost conversions, a reminder message was sent one month before the coupon expired to customers who hadn’t redeemed it yet. This added an extra nudge without being intrusive.

The result? A campaign that was not only successful in driving sales and usage but also provided deep insights. Essilor received detailed store-by-store statistics, from how many coupons were redeemed to how many people viewed the coupon without redeeming it.

With this SMS coupon campaign, Essilor proved that a simple message via the right channel can deliver maximum impact – safe, efficient, and measurable.
