You can use Bird to send and receive messages across email, SMS, WhatsApp, and voice calls through a single API. It handles deliverability setup like SPF/DKIM/DMARC, carrier compliance for SMS (A2P 10DLC), WhatsApp Business API templates, and programmable voice with text-to-speech. It also includes real-time WebSocket pub/sub for live chat and notifications, webhook events per channel, test mode for simulating delivery states, and MCP server support for AI coding agents.
