A WooCommerce email log can show that WordPress attempted to generate a message, while the SMTP provider shows delivery, bounce, suppression, or rejection. Reconcile both layers before changing templates, gateways, or DNS.
Use this when customers say order emails are missing, staff emails are delayed, SMTP shows errors, or WooCommerce email logs do not match inbox evidence.
Quick answer
WooCommerce Email Log to SMTP Provider Reconciliation should be handled with a narrow evidence-first workflow: pick sample orders, match logs, check sender auth, then verify the result before making broader changes.
What to check first
- Choose sample order IDs for new order, failed order, completed order, refund, and customer note messages.
- Match each sample across order notes, WooCommerce email log, SMTP provider event, bounce log, and inbox result.
- Check whether the From address, Reply-To, SPF, DKIM, DMARC, and suppression list explain delivery failure.
- Separate generation failures from provider delivery failures and mailbox filtering.
- Write a short owner-facing table that names the layer and fix for each failed message.
Diagnostic table
Use this table to keep the work practical. It connects the symptom to evidence and a verification step.
| Action | Evidence to collect | How to verify |
|---|
| Pick sample orders | Choose sample order IDs for new order, failed order, completed order, refund, and customer note messages. | Each tested order email has one row across WooCommerce, SMTP, and inbox evidence. |
| Match logs | Match each sample across order notes, WooCommerce email log, SMTP provider event, bounce log, and inbox result. | Generation failures and delivery failures are not mixed together. |
| Check sender auth | Check whether the From address, Reply-To, SPF, DKIM, DMARC, and suppression list explain delivery failure. | Sender authentication and suppression state are checked before template changes. |
| Separate layers | Separate generation failures from provider delivery failures and mailbox filtering. | A new test order reaches the expected inbox and records provider delivery evidence. |
Why this usually happens
- WooCommerce can generate the message correctly while SMTP blocks the sender.
- SMTP can accept a message that the customer mailbox later filters or suppresses.
- An email customizer can break a template before SMTP is involved.
- A bounce or suppression list can affect only specific customers or domains.
Field notes
- Use unique subject markers for test emails so provider search is easy.
- Do not resend customer messages until you understand whether duplicates will confuse fulfillment.
Useful command or data shape
Adapt paths, IDs, and privacy handling to the site before running commands or storing data on production.
email_reconcile:
order_id: 10577
email_type: failed_order
woo_log: generated
smtp_event: deferred
bounce: none
inbox: missing
likely_layer: smtp_provider_or_mailbox_filter
next_step: check sender auth and suppression list
Safe fix order
Do the work in a sequence that makes each result easy to prove. Stop if a step produces new evidence that changes the incident scope.
- Pick sample orders
- Match logs
- Check sender auth
- Separate layers
- Write fix table
What to tell the client or owner
Tell the owner whether the email failed inside WooCommerce, at SMTP, after provider acceptance, or in the recipient mailbox.
Production verification checklist
- Each tested order email has one row across WooCommerce, SMTP, and inbox evidence.
- Generation failures and delivery failures are not mixed together.
- Sender authentication and suppression state are checked before template changes.
- A new test order reaches the expected inbox and records provider delivery evidence.
Mistakes to avoid
- Do not judge the fix by one browser or the homepage only.
- Do not delete evidence before recording usernames, file paths, timestamps, and response headers.
- Do not add a cache, security, or tracking plugin while the original problem is still unclear.
- Do not leave test users, temporary debug logs, or broad API keys active after verification.
