How it works
Sales teams that answer ad leads in minutes, support teams that handle hundreds of chats a day, collections teams that send template reminders, and service areas that need to measure satisfaction on every interaction.
WhatsApp lives in the same inbox as calls, Instagram, Facebook, email and web chat, so your team doesn't jump between tools.
