Symptom

WordPress submitted an email that was not delivered, was rejected, or was filtered.

For: WordPress owners troubleshooting contact forms, password resets, WooCommerce emails, or admin notifications.

Diagnosis

What to check before changing the site

Quick Diagnosis

Separate WordPress sending from mailbox delivery. A successful send log does not guarantee inbox placement.

WooCommerce Note

Order emails add template and status triggers on top of normal mail delivery checks.

From Address Alignment

Use a sender domain the site controls and align it with SMTP, SPF, DKIM, and DMARC policy. Mismatched from addresses often look like sending failures to site owners.

Workflow Tests

Test password reset, contact forms, admin notices, and WooCommerce order emails separately. Each can fail from a different trigger even when the mail provider is healthy.
