# Campaign Stats

Retrieve campaign statistics

## Get email campaign statistics

> Returns aggregated performance metrics for a single campaign: counts and rates for\
> deliveries, opens, clicks, bounces, spam complaints, and unsubscriptions.\
> \
> If the campaign has never been started, all counts and rates are returned as \`0\`.\
> Statistics are aggregated asynchronously and may be slightly delayed for recently sent\
> campaigns.\
> \
> By default, statistics are aggregated over the whole period since the campaign was last\
> started. Use the optional \`start\_date\` and \`end\_date\` query parameters to narrow the\
> aggregation window.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.mailtrap.io/developers/promotional/campaign-stats.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
