Deep Dive

Boost Event Attendance with WhatsApp Automation

Event organizers face immense challenges with ticket drop-offs and low turnout rates. Email invitations are easily ignored. By integrating the Official WhatsApp Business API via HK Reach into your event management software, you guarantee your attendees see your updates.

Automated Reminders & Digital Tickets

Send digital QR code tickets directly via WhatsApp upon registration. Set up automated reminders 24 hours and 1 hour before the event to maximize turnout. You can also share venue maps, parking instructions, and speaker schedules instantly.

Post-Event Feedback & Lead Generation

Once the event concludes, automatically trigger a feedback survey via WhatsApp. For B2B events, use a WhatsApp chatbot to collect lead information from attendees interacting with your booth, seamlessly syncing it back to your CRM.
