Fix email delivery error. China emails
Budget: €30 – €250 EUR
Job Title
WooCommerce transactional emails have intermittent delivery to Outlook (GoDaddy). Email deliverability investigation & fix (incl. China)
Problem Description
We are running a WordPress + WooCommerce website. Our domain email is hosted with GoDaddy and uses Outlook / Microsoft 365.
This is not a case where emails never arrive.
The issue is that system / transactional emails are delivered inconsistently — sometimes they arrive, but often they do not.
This affects emails sent automatically by the website, not manually sent emails.
Affected emails:
• WooCommerce transactional emails:
• Order confirmation
• New order
• Processing / Completed / Cancelled / Failed, etc.
• Messages sent via the Contact Us form
• Other WordPress / plugin notification emails (if applicable)
Additionally, there were previous issues where customers did not receive order confirmation emails on Chinese email providers (e.g. qq.com, 163.com, 126.com, etc.). This must also be reviewed and addressed as part of this task.
Symptoms (Important)
• Some transactional emails are delivered successfully.
• Many others are missing or blocked.
• The task is to identify whether:
• emails are not always sent by WordPress/WooCommerce, OR
• emails are sent but not delivered due to Outlook / GoDaddy / DNS / reputation / regional filtering issues.
Environment
• WordPress + WooCommerce
• Email hosting: GoDaddy → Outlook (Microsoft 365)
• DNS managed in GoDaddy
Access will be provided if required:
• WordPress admin
• DNS (GoDaddy)
• Outlook / Microsoft 365 admin
Scope of Work
1) Diagnostics
• Review how emails are currently sent from the website (wp_mail, SMTP plugin, relay, etc.).
• Check WooCommerce email triggers and configuration.
• Review Contact Us form email setup (From, Reply-To, headers).
• Review available logs (WordPress, WooCommerce, mail logs) to identify where failures occur.
2) GoDaddy / Outlook Support Coordination (Mandatory)
• Communicate directly with GoDaddy support if needed.
• Work together with GoDaddy to:
• identify filtering, blocking, or policy issues
• verify email authentication and domain reputation
• Clearly instruct GoDaddy support on what must be checked or adjusted.
• Escalate the issue if necessary until the root cause is identified.
3) China Email Deliverability
• Review issues related to Chinese email providers.
• Identify technical reasons for delivery failures (authentication, headers, encoding, reputation).
• Apply best practices to improve delivery to Chinese mails
4) Testing
• Perform multiple test orders in WooCommerce and verify email delivery.
• Test Contact Us form submissions.
• Test delivery from and to:
• our Outlook inbox
• Gmail
• Chinese email domains (if test addresses are provided)
5) Final Report & Documentation
• Explain clearly why emails were delivered intermittently.
• Provide a summary of all actions taken (including communication with GoDaddy support).
• Provide recommendations to keep email delivery stable going forward.
Success Criteria
• WooCommerce transactional emails are delivered consistently, not randomly.
• Contact form emails arrive reliably.
• Deliverability is improved for international recipients, mainly China
• Tests confirm stable delivery
