## 从提示到 送达。

从你的应用或智能体发送邮件，全程跟踪投递状态。 通过 MCP 和 CLI 实现完整的读写访问。

**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
```

## They take an action. You keep them informed.

Help a customer get back into their account, confirm a purchase or follow a delivery. Your application sends the email when the action happens, with the details that person needs next.

## Did the email arrive? Find the answer.

Search the email log by recipient or message ID. Open the message to see its delivery history, including deferrals and bounces, then use signed webhooks to bring those updates back into your application.

## Transactional email, explained.

### What is transactional email?

Transactional email is a message a customer expects after an action: a password reset, purchase receipt, booking confirmation or account update. Your application sends it to the person involved. Newsletters, promotions and audience campaigns belong in Email marketing.

### Can I use SMTP instead of the API?

Yes. Bird SMTP and the Email API use the same sending infrastructure, domain verification, suppression handling and reporting. Choose the submission method your application supports.

### Does delivered mean the email reached the inbox?

Delivered means the receiving mail server accepted the message. Inbox Insights measures inbox and spam placement separately through seed accounts and a measurement panel.
