Know the moment your WordPress emails stop arriving.
Password resets, order confirmations, contact forms — when wp_mail() fails silently, you lose customers before you ever find out. DeliverScope Pro watches your email around the clock and alerts you the instant something breaks.
Silent email failure is expensive
- Password resets never arrive → frustrated users who can’t log in.
- Order confirmations go missing → support tickets and chargebacks pile up.
- Contact-form leads vanish → lost revenue you never knew existed.
Most site owners don’t discover the problem until a customer complains. By then the damage is done.
