About This Project
A WooCommerce store owner came to me with a frustrating problem — all the forms on their website appeared to work perfectly from the frontend, but emails were simply not reaching anyone’s inbox. Customers were filling out contact forms, placing orders, and requesting password resets, but neither the customer nor the store owner was receiving any email notifications.
The root cause was that WordPress by default uses the PHP mail() function to send emails, which most hosting servers either block or don’t properly configure — causing all outgoing emails to silently fail or land in spam. WooCommerce order confirmation emails, new order alerts, customer invoice emails, shipping notifications, and password reset emails were all affected. I configured a proper SMTP setup using WP Mail SMTP plugin, connected it to a reliable email-sending service, tested all form types and WooCommerce email notifications, and confirmed full delivery to inbox. The client’s store is now sending every email reliably without any issues.
