Reach customers where they already chat. Two billion users. One inbox, threaded with the rest.

What it does
WhatsApp Business runs on the same per-tenant Twilio subaccount that powers SMS and voice. Same provisioning, same A2P registration where applicable, same routing logic — no separate vendor to onboard.
Conversations land in the unified inbox alongside email, SMS, and voice. Threaded by contact, searchable across channels, with full history. Send proactive messages or reply inline; both look identical to your team.
Workflows trigger WhatsApp sends just like SMS or email. Use it for high-priority alerts (appointment reminders, order confirmations, support escalations) where SMS open rates aren't enough.
Delivery and read receipts ship out of the box, exposed to workflows so you can branch on whether a message was actually opened. Webhook → engine → workflow runner: no manual polling.
