It evaluates your setup against 2024+ Gmail, Yahoo, and Outlook bulk sender requirements and gives you a clear **Deliverability Health Score (0– 100)** with plain-English fixes. ### Why You Need This * **Silent Failures:** Stores often have no idea that order emails are going to spam until frustrated customers complain. * **Strict 2024+ Mail Requirements:** Major mailbox providers (Google, Yahoo, Microsoft) now actively reject or spam-box unauthenticated emails sent from domains without proper SPF, DKIM, and DMARC alignment. * **WooCommerce-Aware Context:** Unlike generic DNS checkers, this plugin cross- references your DNS health directly with your WooCommerce email templates (Order Processing, Completed, Customer Invoice, Password Reset) to show you exactly which transactional emails are at risk. ### Core Features * **Instant Health Score (0–100):** Visual animated score ring that rates your overall deliverability readiness. * **SPF Record Audit:** Verifies the existence and syntax of SPF records (`v=spf1`) on your sending domain. * **DMARC Record Audit:** Checks if `_dmarc` policy is published to protect your domain reputation. * **DKIM Selector Probing:** Checks common selector patterns (`default`, `google`,` k1`, `mail`, etc.) to detect DKIM signing status. * **Sender Alignment Check:** Confirms whether your WooCommerce “From” address domain matches your store domain. * **Public Webmail Detector:** Flags dangerous configurations (e.g. sending as `@ gmail.com` or `@yahoo.com`), which trigger instant spam filters. * **SMTP Provider Detection:** Identifies if an authenticated SMTP/API mailer plugin is active (WP Mail SMTP, FluentSMTP, Post SMTP, etc.). * **WooCommerce Email Risk Table:** Assesses every registered WooCommerce transactional email and ranks customer-facing emails by risk level. * **Actionable Step-by-Step Fixes:** Plain-English instructions for resolving every detected warning or failure. * **One-Click AJAX Re-Scan:** Test DNS changes instantly without refreshing the page. * **Lightweight & Secure:** Zero frontend impact, transient-cached DNS lookups ( 6-hour TTL), rate-limited scanning, and strict capability checks. * **HPOS Ready:** Fully declared and compatible with High-Performance Order Storage( HPOS). ## Screenshots [⌊Deliverability Overview & Health Score: Animated score ring, category compliance breakdown, quick stats, and prioritized action checklist.⌉⌊Deliverability Overview& Health Score: Animated score ring, category compliance breakdown, quick stats, and prioritized action checklist.⌉[ **Deliverability Overview & Health Score:** Animated score ring, category compliance breakdown, quick stats, and prioritized action checklist.

No. InbxGuard Email Deliverability Auditor is strictly a read-only diagnostic and auditing tool. It inspects your DNS records and WooCommerce configuration to report issues, but does not alter your outgoing email content or sending flow. ### Does this replace SMTP plugins like WP Mail SMTP or FluentSMTP? No, it complements them. SMTP plugins handle _how_ your email is sent through external mail servers. InbxGuard checks _why_ emails might still land in spam (DNS authentication, SPF/DKIM/DMARC alignment, and sender reputation rules). ### What if my DKIM check shows a warning? DKIM selectors are unique to your email provider (e.g. Google Workspace, Amazon SES, Brevo, SendGrid). The auditor checks the most common selector names automatically. If you use a custom selector, your emails may still be signed properly—simply verify the selector in your SMTP service dashboard. ### Does running audits slow down my store? Not at all. DNS lookup results are cached using WordPress transients for 6 hours, and re-scans are throttled to a maximum of once every 30 seconds. There is zero overhead on customer-facing store pages. ### Is this plugin compatible with WooCommerce HPOS (High-Performance Order Storage)? Yes! HPOS compatibility is officially declared and verified for modern WooCommerce releases (8.0+ through 9.3+). ## Reviews There are no reviews for this plugin. ## Contributors & Developers “InbxGuard Email Deliverability Auditor for WooCommerce” is open source software.
