# Get email metrics

Returns the account's delivery and engagement counts and rates, such as sent, delivered, open, click, bounce and unsubscribe, for a date range as totals or by period, domain, email or broadcast.

Note: Rates are percentages. Opens and clicks need tracking on the sending domain. Data older than the plan keeps is dropped, so check `start_date` in the response. The `email` and `broadcast` dimensions can't be combined. Edge periods can be partial; results cache 15 minutes.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

```json
{ "mcpServers": { "resend": { "url": "https://mcp.resend.com/mcp" } } }
```

Call the MCP tool `get-email-metrics`.

Server URL: https://mcp.resend.com/mcp

### CLI (official)

Install the command, then confirm it runs.

```sh
npm install -g resend-cli
resend --version
```

Run `resend emails metrics`.

Set `$RESEND_API_KEY` in your environment first (get a key: https://resend.com/api-keys).

### API (official)

- Base URL: https://api.resend.com
- Endpoint: `GET /emails/metrics`
- Auth: send the header `Authorization: Bearer $RESEND_API_KEY`
- Get a key: https://resend.com/api-keys
- Docs: https://resend.com/docs/api-reference/introduction

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
