# Resend charts

> Browse all Resend transactional email charts in Chartcastr including daily send volume, delivery success rates, and bounce or complaint tracking.

Chartcastr supports **2 pre-built Resend metrics** for tracking email delivery health.

## Email Delivery

| Metric                    | Chart Type  | Description                                                    |
| ------------------------- | ----------- | -------------------------------------------------------------- |
| **Emails Sent Per Day**   | Bar         | Total emails sent each day over the last 30 days               |
| **Email Delivery Status** | Stacked Bar | Breakdown of delivered, bounced, and complained emails per day |

<Note>
  **Email Delivery Status** is the recommended starting metric — it shows volume alongside delivery health in a single chart. A growing bounce or complaint rate is flagged automatically by the AI summary.

## AI-Powered Summaries

Every Resend chart is delivered with an AI-generated summary specific to email delivery:

* **Emails Sent**: volume trends, day-of-week patterns, spike/drop detection
* **Delivery Status**: bounce rate trends, complaint rate changes, deliverability health signals
