WhatsApp Bot Development for a Hanukkah Campaign – Coca-Cola

in: Apps, Chatbots Development

As part of a digital Hanukkah campaign for Coca-Cola, we developed a smart WhatsApp bot that delivered a personalized, emotional, and highly engaging user experience — combining data collection, regulatory compliance, and strong call-to-action mechanics.

🎯 Project Goals

The campaign aimed to encourage product purchases through receipt submission, create an emotional connection with the brand באמצעות user-generated content, and collect high-quality leads while fully complying with privacy and marketing regulations.

🧠 User Experience Design (UX Flow)

The bot was designed as a simple yet precise flow, guiding users naturally through each step:

• Regulatory Approvals
  Users are required to approve marketing communications, terms & conditions, and privacy policy — including transparency לגבי שימוש במידע, cookies, and tracking pixels (Google / Facebook), as a condition for participation.

• Receipt Entry
  Users validate their participation by entering a purchase receipt number.

• Open Content Question ✨
  Users are invited to share a personal story:
  “In honor of Hanukkah, tell us about a moment that brightened and touched your day.”
  This step creates emotional engagement and deeper brand connection.

• Contact Details Collection & Validation
  Users select or enter a phone number for potential prize notifications, with validation and retry prompts for incorrect inputs.

• Viral Sharing
  A WhatsApp share message is generated with a direct participation link to boost organic reach.

• Reminder (Nudge) System to Prevent Drop-offs ⏰
  The bot includes an automated reminder system that re-engages users who did not complete the flow. Smart, friendly messages are sent based on the stage where the user dropped off, helping increase completion rates.
