Bird was founded in 2011 as MessageBird. It offers APIs for email, SMS, WhatsApp, Apple Messages for Business and voice. It also ships an MCP server, a CLI and skills so AI agents can set up channels and send messages directly.
From bird.com/pricing:
Email has free and paid plans. Voice is priced per minute.
Bird does not offer phone-number iMessage like Linq. Its Apple channel is Apple Messages for Business, where customers start the conversation and brands go through Apple's registration. Bird adds email and WhatsApp. It prices per message, while Linq uses flat monthly plans. Both say they have SOC 2 Type II reports.
Developers who want email, SMS, WhatsApp and Apple Messages for Business from one vendor, with tooling for AI agents.
