Bird (formerly MessageBird, includes SparkPost)
Email API for developers: send and receive email from your app or agent
Bird is a communications platform that lets developers and AI agents send and manage messages across email, SMS, WhatsApp, Apple Messages, and Voice through a single API. It addresses the need to connect application events and customer conversations across channels, with tooling for testing requests, tracing delivery, verifying webhook signatures, and recovering from errors.
Core capabilities include transactional email and campaigns, WhatsApp templates, visual automations, voice call flows, email mailboxes, contacts and audiences, and analytics for each channel. Additional modules cover Verify, Lookup, Mailbox, eSIM, Realtime, and phone numbers. Developers work through SDKs (Node.js, Python, Go, PHP), a CLI, REST API, and a hosted MCP that gives agents read and write access. SparkPost, PowerMTA, and Momentum are listed as email delivery options. Integrations span CRM, marketing, data warehouse, ecommerce, and AI tools, and the platform supports workspaces, team roles, API authentication, and audit logs.
Bird is aimed at developers, product teams, and organizations operating at scale, with an Enterprise offering for security and compliance review. Pricing combines free tiers, pay-as-you-go usage, product plans, and custom agreements; developer tools are included while underlying API usage is billed separately.
