# Retrieve email statistics by browser.

## API Overview

Tracking your emails is an important part of being a good sender and learning about how your users interact with your email. This includes everything from basics of clicks and opens to looking at which browsers and mailbox providers your customers use.

We have broken up statistics in specific ways so that you can get at-a-glance data, as well as allowing you to get into the details of how your email is being used.

> \[!NOTE]
>
> Category statistics are available for the previous thirteen months only.

## Operation overview

```json
{"path":"https://api.sendgrid.com/v3/browsers/stats","method":"get","servers":[{"url":"https://api.sendgrid.com","description":"for global users and subusers"},{"url":"https://api.eu.sendgrid.com","description":"for EU regional subusers"}]}
```

**This endpoint allows you to retrieve your email statistics segmented by browser type.**

**We only store up to 7 days of email activity in our database.** By default, 500 items will be returned per request via the Advanced Stats API endpoints.

Advanced Stats provide a more in-depth view of your email statistics and the actions taken by your recipients. You can segment these statistics by geographic location, device type, client type, browser, and mailbox provider. For more information about statistics, please see our [Statistics Overview](/docs/sendgrid/ui/analytics-and-reporting/stats-overview/).
