About DeliverScope
From the official readme · v1.0.5Description
“Why didn’t I get your email?”
Sound familiar? WordPress email failures are silent killers:
- Password resets never arrive → frustrated users
- Order confirmations go missing → support tickets pile up
- Contact form submissions vanish → lost leads and revenue
Most site owners don’t know their emails are failing until customers complain. By then, the damage is done.
DeliverScope gives you complete visibility into your WordPress email system.

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.
