# Retrieve a specific alert

## API Overview

Twilio SendGrid's Alerts feature allows you to receive notifications regarding your usage or program statistics from SendGrid at an email address you specify.

### Email credit usage

Usage alerts allow you to set a threshold, when you've used 90% of your email credits, for example, at which point an alert will be sent to your email.

### Statistics summary

Statistics notifications, including email statistics, bounces, spam reports, and category statistics, can be delivered to your email address at one of three frequencies: **Daily**, **Weekly**, or **Monthly**.

See the [**Statistics Overview**](/docs/sendgrid/ui/analytics-and-reporting/stats-overview) for more information about the various statistics SendGrid provides about your email.
