Your team is taking turns logging into one WhatsApp account
You or your staff spend hours manually replying to the same questions
You want to send promotions or updates to hundreds or thousands of contacts
Customers message outside business hours and get no response
You have no visibility into message delivery or read rates
You want WhatsApp to automatically trigger when an order is placed or payment received
You need to send OTP or TAC verification codes via WhatsApp
You're a bank, insurer, clinic, or regulated business needing compliant messaging
If any of the above applies to your business, you're ready for WhatsApp Business API.
