Resend charts - Chartcastr

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

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
