Get email metrics

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)

Call the MCP tool get-email-metrics.

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

CLI (official)

Install the command, then confirm it runs.

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)

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.
