Hi Product Hunt! I'm Nacho, founder of Zellbox. We built Zellbox after watching clinics and service teams juggle three browser tabs all day: Google Calendar for visits, WhatsApp Business on someone's personal phone, and Gmail for everything else. Reminders were sent by hand, no-shows piled up, and customer history lived in scattered chats. Zellbox puts it all in one place: - Automatic WhatsApp reminders (24h, 2h, post-visit) on Meta's official Cloud API - Two-way Google Calendar sync and Gmail sending from your own address - One shared inbox per customer: WhatsApp + email together - Meta Coexistence: keep using WhatsApp Business on your phone, same number, same history - No per-seat pricing, free plan, setup in about 5 minutes If you're using Callbell, WATI or a spreadsheet + WhatsApp today, we'd love to hear what you'd need to switch. Happy to answer any questions!
