How the M-Social team developed a landing page for OSKELLY and Coffeemania

When OSKELLY dessert appeared in Coffeemania, it immediately stood out — not only for its taste, but also for the fact that it offered a chance to win a prize. The code was hidden under the scratch layer in the envelope, and behind it was a gift: from a keychain to an invitation to a Hermès Kelly bag raffle.

For the promotion to work, a reliable tool for registering winners was needed. The M-Social team developed and launched a landing page where participants entered codes and instantly learned about their winnings.

What We Did

Built the landing page from the layout

Responsively: for both mobile (main traffic came from the OSKELLY app) and desktop.

Built the forms

Registration: with validation for name (Cyrillic only), phone (mask +7), email, and code.

Verification: 4-digit code, timer for resending, choice between SMS and WhatsApp, "SMS not arriving" hint.

Added Yandex.Captcha

To prevent bots from registering codes for people.

Configured prize distribution logic
Integrated with Mindbox

All participant data immediately went into the client's CRM.

Built an admin panel on Backpack (Laravel)

The functionality allowed:

Viewing all participants

Filtering by prize type, date, phone number, etc.

Searching by any field

Exporting to CSV, XLSX, PDF, or printing

Configured robots.txt

How It Went

Over three weeks, tens of thousands of users completed registration.
Thousands of prizes were distributed, including:

Loyalty program points for "Кофемания" (Kofemania) of various denominations.
Discount promo codes from the OSKELLY brand for order totals.
Refreshing watermelon frescos.
Stylish branded keychains.
Invitations to participate in the main prize draw.

Outcome

The site ran without failures even during peak times. The admin panel helped quickly find users and generate reports. And most importantly — participants received their prizes and were satisfied.
