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
