M Media Email Deliverability Inspector

M Media Email Deliverability Inspector is a WordPress plugin designed to help site owners, developers, and agencies verify email authentication and deliverability directly within their WordPress installations. It addresses the common problem of undelivered emails—such as order confirmations or password resets—by providing instant diagnostics before messages are sent, aiming to prevent silent and costly deliverability failures.

The tool performs comprehensive checks on several key email authentication mechanisms and infrastructure settings. It verifies SPF records to confirm which servers are authorized to send email for a domain, validates DKIM signatures with support for custom selectors, and checks DMARC policies for enforcement and alignment. Additionally, it inspects MX records to ensure proper inbound mail routing, confirms PTR (reverse DNS) for IP reputation alignment, and includes an SMTP test that sends a real email to confirm end-to-end delivery. Each diagnostic provides a clear pass/fail status, human-readable explanations, and actionable guidance if misconfigurations are detected.

M Media Email Deliverability Inspector operates entirely locally within the WordPress environment, performing DNS lookups and optional SMTP tests using standard internet protocols. No data leaves the user's server, and results can be exported as JSON for documentation or audit purposes. The plugin is built for those who want accurate answers without relying on SaaS services, accounts, APIs, or tracking. It is particularly suited for WooCommerce stores sending transactional emails, developers setting up new WordPress sites, agencies validating client infrastructure, and anyone seeking clarity on email deliverability issues.

The licensing model is a one-time purchase that grants lifetime access, with no subscriptions, cloud authentication, or forced updates. Users retain full control over their data and can choose when to upgrade. The software is designed to work offline and survive reinstalls, emphasizing durability and user empowerment. This approach ensures that the tool remains available and functional regardless of payment or server changes.
