WordPress email has always had a strange failure mode. Your site can say it sent the email. Your SMTP plugin can say it accepted the email. Your form plugin can say the notification was triggered.
And still, the email may never reach the inbox. That gap is exactly what Scanfully 1.9 focuses on.
With version 1.9, Scanfully introduces Email Deliverability Monitoring. It runs full end-to-end email checks from your WordPress website to an actual inbox. That means Scanfully does not only check whether WordPress tried to send an email. It checks whether that email reached its destination.
For forms, account emails, password resets, WooCommerce notifications, admin alerts, or booking confirmations, “sent” is not the same as “delivered.”
Why WordPress email needs real monitoring
WordPress email often looks simple from the outside. A plugin calls wp_mail(). WordPress passes the message to the configured mail system. The site moves on. But that is only one part of the route.
After WordPress hands off the email, the message may still pass through a mail transport, an SMTP service, DNS authentication checks, reputation systems, spam filters, and receiving mail servers.
Any part of that chain can fail, and worse, many failures do not show up inside WordPress.
A contact form notification can disappear. A password reset can never arrive. A customer email can land in spam. A plugin alert can fail silently. The site may stay online, fast, and healthy, while an important workflow stops working in the background.
That is why email deliverability belongs inside Scanfully.
Scanfully already monitors the parts of a WordPress site that affect reliability: uptime, performance, certificate health, Site Health, activity, content health, and plugin security. Email now becomes part of that same picture.
What Email Deliverability Monitoring checks
Scanfully 1.9 adds a dedicated email deliverability service. The feature tests the path between WordPress and the inbox.
It includes:
- End-to-end email testing from the WordPress site to an actual inbox
wp_mail()validation- WordPress mail transport validation
- SPF checks
- DKIM checks
- DMARC checks
- RBL and DNSBL blocklist checks
- Deliverability state evaluation after inbound pings
- Header diagnostics where they help explain delivery behavior
This gives Scanfully a clearer view of whether email works beyond the first handoff. wp_mail() can confirm that WordPress passed an email to the next layer.
It cannot confirm that the message reached a real inbox. Scanfully 1.9 checks the FULL route.
Blocklists and sender reputation
Email deliverability problems often send people in the wrong direction. It is common to start by changing a form plugin, adjusting notification settings, swapping SMTP plugins, or editing email templates.
Sometimes that helps. But sometimes the real problem sits outside WordPress.
Our Email Deliverability monitoring checks the IP address against known blocklists. A sending IP can appear on a DNS-based blocklist. A mail provider can route through infrastructure with a poor reputation. A domain can have authentication issues. A receiving server can distrust the message regardless of its content.
Scanfully 1.9 adds RBL and DNSBL blocklist checks so you can see that signal sooner.
This does not replace deeper email infrastructure work. However, it gives you a better starting point. Instead of guessing whether the issue lives in WordPress, SMTP, DNS, or sender reputation, Scanfully can show useful evidence from the monitoring layer.
Catching delivery failures
Email is part of the user experience, even when users never see the system behind it.
Users notice when password resets, order emails, or contact form leads fail to arrive. Scanfully 1.9 helps catch those problems earlier.
With Email Deliverability Monitoring, Scanfully now checks whether WordPress email works beyond the initial send attempt. It validates the mail path, checks important DNS authentication records, watches for blocklist issues, and confirms whether the test message reaches an actual inbox.
Scanfully 1.9 is available now.
