An excellent and reliable service for message delivery. You only need to set it up once, and it will work steadily. I have integration with YClients, and I see all messages sent via WhatsApp directly in the system. The service automatically sends reminders about appointments and requests confirmations, and there is no confusion: the message goes to exactly the person it should. Throughout my usage, I have only noticed minor glitches when it couldn't send a message for a few minutes. It's unclear whose side the problem was on – ChatPush or WhatsApp. But usually, everything would fix itself within 5-10 minutes.
