This guide gets you from zero to a working send-and-receive workflow quickly.

## Quickstart path

1. Install an SDK.
2. Add your API key via environment variable.
3. Create an inbox.
4. Send a message.
5. Wait for and assert the received message.

## 1) Install an SDK

JavaScript client:

```bash
npm install --save mailslurp-client
```

Other official SDKs: [MailSlurp SDK docs](/docs/).

## 2) Configure your API key

Create a key in the dashboard and inject it into your environment:

```bash
export MAILSLURP_API_KEY="your-key"
```

API-key setup details: [API key guide](/guides/api-key/).

## 3) Create a MailSlurp client

```typescript
import { MailSlurp } from "mailslurp-client";

const mailslurp = new MailSlurp({
  apiKey: process.env.MAILSLURP_API_KEY,
});
```

## 4) Create an inbox and send a test message

```typescript
const inbox = await mailslurp.createInbox();

await mailslurp.sendEmail(inbox.id, {
  to: [inbox.emailAddress],
  subject: "Quickstart check",
  body: "Hello from MailSlurp",
});
```

## 5) Wait for delivery and assert content

```typescript
const email = await mailslurp.waitForLatestEmail(inbox.id, 30_000, true);

if (!email.subject?.includes("Quickstart check")) {
  throw new Error("Unexpected subject");
}
```
