Why DeliverScope?
vs. Default WordPress email: wp_mail() fails silently. No logs, no alerts, no way to know something’s wrong.
vs. Other SMTP plugins: Most plugins only configure SMTP. DeliverScope monitors it and alerts you to problems.
vs. External services: No complex setup or monthly fees. DeliverScope lives inside WordPress where your emails originate.

Complete automated monitoring:
- Scheduled Canary Tests – Automated emails every 5-60 minutes catch failures even at 3am
