About Sendzai

Sendzai is the world's most advanced WhatsApp automation hub, designed to bridge high-volume campaign orchestration with developer/AI-agent workflows. Whether you are a marketing team launching sequential media campaigns or a developer looking to trigger WhatsApp messages from AI agents, Sendzai provides the complete command center. For businesses and marketing teams, Sendzai offers a visual dashboard to compose sequential messaging flows. Its "Ghost Engine" protects your phone numbers using randomized human delays, recipient timezone-aware scheduling, and account sharding (automatically distributing campaign loads across up to 50 active WhatsApp accounts). For developers, Sendzai introduces native Model Context Protocol (MCP) server support and an automated CLI (sendzai). This allows custom code, LLMs, and autonomous AI agents to query session health, post status updates, lookup contacts, and dispatch message pipelines directly from terminal commands or LLM function-calls.

Overview

Who is it for?

High-growth SaaS & e-commerce brands, marketing agencies, and AI developers building messaging-driven workflows.

Problem

Expensive Official APIs: Businesses are forced to pay steep per-message fees on the official WhatsApp Business API, making bulk campaigns cost-prohibitive. High Ban Risks: Automating standard WhatsApp accounts with simple, repetitive scripts leads to swift account bans due to robotic patterns. Fragmented Workflows: Marketing teams cannot easily stack media sequences (sending an image, followed by a PDF, followed by text) without a custom setup. No AI Agent Integration: Modern AI agents (LLMs) lack a standardized, native protocol (like MCP) to directly interact with WhatsApp channels.

Solution

Sendzai is the ultimate zero-friction WhatsApp command center. Link your existing WhatsApp numbers in seconds via a simple QR code scan, build high-converting media-rich campaigns, and let our persistent cloud engine drive massive engagement. Developers can also instantly plug in the built-in MCP server to let AI agents orchestrate chat workflows autonomously—with zero official API approval delays.

What makes it unique

First-of-its-Kind MCP & AI Agent Support: The world's first WhatsApp platform built natively for the AI era. With out-of-the-box Model Context Protocol (MCP) server support, your autonomous LLM agents (using Claude, GPT, etc.) can read metrics, manage sessions, and send campaigns on your behalf. Built-in Ban Defense (The "Ghost Engine"): We don't just send messages; we mimic real humans. Sendzai uses randomized human typing delays, recipient timezone-matched dispatching, and automated account sharding (splitting campaigns across up to 50 active numbers) so your accounts stay safe and scale indefinitely.
