WordPress Email Deliverability Guide

Diagnose WordPress and WooCommerce email problems by separating trigger behavior, SMTP sending, DNS authentication, and mailbox delivery.

Problem

Email failures are often misdiagnosed because sending, acceptance, filtering, and template triggers happen in different systems.

For: Site owners and store teams who need reliable operational email.

Workflow

Confirm WordPress or WooCommerce actually attempted the email, and that the event or order status should trigger that template.

Review SMTP or mail-provider logs, sender alignment, authentication, and provider limits.

Check spam placement, recipient filtering, DNS authentication, and bounce details before changing site code.
