Description
Stop losing customer trust and sales because WooCommerce order confirmation, shipping notices, or password-reset emails silently land in customer spam folders.
InbxGuard Email Deliverability Auditor for WooCommerce runs automated, non-intrusive diagnostic checks against your store’s email authentication records and WooCommerce sender configuration. 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
_dmarcpolicy 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.comor@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).

FAQ
-
Does this plugin send or alter my store’s emails?
-
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+).
