--- title: "Email API for developers" canonical: "https://bird.com/email-api" --- # Email API for developers Send and receive email from your app or agent. Build with Bird MCP, CLI, and SDKs. [Get Started](/dashboard/signup?returnTo=%2Fdashboard%2Fw%2Femail) [Contact Sales](/demo?product=email) [Read customer stories](/customers) [Explore Enterprise](/enterprise) - [Airwallex](/customers/airwallex) - [Glovo](/customers/glovo) - [Zillow](/customers/zillow) - Uber - [Binance](/customers/binance) - Adobe - Meta - PayPal - Pinterest - Square - [Al Jazeera](/customers/aljazeera) - [Aramex](/customers/aramex) - [Bazaar Technologies](/customers/bazaar) - [ComparaOnline](/customers/compara) - [Emma](/customers/emma) ## From prompt to delivered. Build [transactional email](/email-api/features/transactional-email), [marketing campaigns](/email-api/features/email-marketing) and [agent mailboxes](/mailbox-api) on one platform. Send, manage and inspect email through the API, SDKs, CLI or hosted MCP. **MCP**: `Bird MCP` Connect this hosted MCP endpoint with an [MCP client](/docs/ai/mcp-server#connect-a-client), then complete OAuth sign-in to your Bird workspace. Example prompt: Send a welcome email to delivered@messagebird.dev from onboarding@messagebird.dev, then check it arrived. ```text https://mcp.bird.com ``` Examples: [MCP](/email-api.mcp.md) · [CLI](/email-api.cli.md) · [TypeScript](/email-api.ts.md) · [Python](/email-api.py.md) · [Go](/email-api.go.md) · [PHP](/email-api.php.md) · [cURL](/email-api.curl.md) ## Your domain. Your reputation. Verify your sending identity. Manage reputation as your volume grows. [Domain setup](/docs/guides/email/sending-domains)[DKIM, SPF & DMARC](/docs/guides/email/dkim-spf-dmarc)[Dedicated IPs](/docs/guides/email/dedicated-ips-and-pools)[Suppressions](/docs/guides/email/suppressions) ## Less debugging. More building. Test requests, trace delivery, and recover from errors with clear feedback at every step. ### Test the failure paths. Trigger real delivery events without sending to a real inbox. ### Errors you can act on. The field, the reason, and the next step. For you and your agents. ### Handle delivery events. Verify webhook signatures with the SDK, then act on delivery events. ### Retry with confidence. Retry with the same key and body to retrieve the original response. Keys are retained for roughly three hours.

[Get Started](/dashboard/signup?returnTo=%2Fdashboard%2Fw%2Femail)[Contact Sales](/demo?product=email) ## Your template. Their email. Render React Email to HTML, or use a published template. Personalize transactional email with values from your app, and send campaigns to opted-in audiences.

A clearer picture. Follow delivery over time and trace a bounce to its receiving-server response. Delivery events confirm server acceptance; Inbox Insights provides sampled placement estimates. [Email analytics](/docs/guides/email/tracking-and-metrics)[Inbox Insights](/email-api/features/inbox-insights)[Competitive Insights](/email-api/features/competitive-insights) ## Receive the reply. Build what happens next. Receive email on your domain or a forwarding address. Use the webhook’s message reference to fetch the body and attachments. Give an agent a persistent mailbox to follow threads and reply.
