Start with the order status, then check WooCommerce’s transactional email log. A log entry marked Sent means the message was handed off—not that it reached the inbox.
First, check whether the order should have triggered an email
Open the order in your WordPress admin and check its status alongside the payment result. A Pending Payment order does not trigger the expected order email. A shopper may have abandoned an external payment flow or had a card declined; if payment succeeded but the order is still Pending Payment, investigate why the payment gateway did not update the status. That is an order-processing problem, not proof of an email-delivery failure. A plugin, theme, or custom-code error may also interrupt processing before the status changes.

Email triggers depend on both the notification type and the order state. For example, WooCommerce documents the Processing order email after payment and the Completed order email after an order is marked complete. Extensions and custom code can add their own notifications, so identify the exact message that is missing before troubleshooting it.
Confirm the exact notification is enabled
- In WP Admin, go to WooCommerce > Settings > Emails.
- Select the notification that should have been sent.
- Check that Enable this email notification is selected. WooCommerce’s Email Settings documentation describes the available notification and sender settings.
- If it is an admin or shop-manager message, check that its recipient address is present and correct.
An enabled notification should generate for an order successfully updated to Processing. If the order reached the expected status and the notification is enabled, use the log next to see whether WooCommerce attempted to send it.
#1 Best Overall
Read the transactional email log
Create a test order or trigger the specific email, then go to WooCommerce > Status > Logs and filter for transactional-emails. WooCommerce’s Email troubleshooting documentation defines these outcomes:
- Sent: WooCommerce handed the message to the site’s mail system. It does not confirm inbox delivery.
- Failed: The mail-sending process returned an error. Inspect the reason shown and check the host or mailer configuration.
- Disabled: The notification is turned off in WooCommerce settings.
- Skipped: A required condition was missing, such as a recipient address.
For order-related emails, sent and failed attempts also appear as private order notes. Disabled and skipped outcomes appear in the log but not as order notes. The transactional email log may not include WordPress password resets or other WordPress admin messages; use SMTP-provider logs or a mail logging plugin to trace those.
Rank #2
If no log entry appears
First confirm the order or action should have triggered the notification and that the email is enabled. Then check WooCommerce > Status > Logs > Settings: logging must be enabled, and the threshold must not hide INFO or NOTICE events. If those settings are right, inspect fatal-error logs and test for a plugin, theme, or custom-code conflict. Reproduce the issue in a safe troubleshooting session with other extensions disabled and a default theme rather than changing a live storefront blindly.
If the log says Sent but nobody received the email
WooCommerce’s Email and SMTP providers documentation explains that WooCommerce creates the message and calls WordPress’s wp_mail() function. In its own words, “By default, WooCommerce sends mail using the wp_mail() function, a core function of WordPress.” wp_mail() initiates processing; it is not an email server. In the default route, WordPress delegates through PHP to a local mail server on the host. A successful handoff can still be followed by spam filtering, rejection, or non-delivery.
- Check the recipient’s junk or spam folder and filtering rules.
- Use a From address on your store’s own domain rather than a public address such as Gmail or Yahoo. See WooCommerce’s email authentication and sender requirements.
- Ask your host or mail provider to confirm that outbound mail for the sending domain is authenticated with SPF, DKIM, and DMARC.
- If the host’s local mail route is unreliable, consider an authenticated SMTP or transactional-email provider. Check the provider’s current setup requirements, cost, and sending limits rather than assuming they are the same across services.
- Send a test message, check its authentication with an email-testing service, and review provider logs for acceptance, bounce, or rejection details.
Provider logs and tests can help separate a handoff problem from a recipient-side filtering or rejection problem; the WooCommerce log alone cannot establish that a customer received the message.
If the log says Failed, Disabled, or Skipped
| Log result | What to check |
|---|---|
| Failed | Read the returned error. Check hosting or SMTP credentials, the connection, sender authorization, and the mail provider’s logs. |
| Disabled | Enable the corresponding notification under WooCommerce > Settings > Emails. |
| Skipped | Resolve the missing condition shown in the log, commonly a missing recipient address. |
Choosing a more reliable sending route
If the default host mail route fails or cannot provide useful diagnostics, an SMTP plugin or mailer can route messages through an authenticated provider. WooCommerce lists examples such as Brevo, Gmail or Google Workspace, Microsoft 365 or Outlook, Mailgun, SendGrid, Postmark, and Maileroo in its provider documentation. The list is not a universal ranking or endorsement; provider availability, authentication requirements, pricing, and limits can change.
Choose based on whether the host route is adequate, whether you can authenticate and authorize your store’s sender domain, and whether the service offers the test, error, bounce, and delivery logs you need. If you use an extension to connect a provider or centralize logs, confirm its current features and compatibility with your installed WooCommerce version. WooCommerce’s SMTP & Email Logs documentation describes its extension’s provider connections, test email, logs, fallback, and resend features.
