WooCommerce 10.9: New Checkout and Email Features for Your Store

Your online store’s performance is the most important factor in closing sales online. Every second your customers wait on the checkout page increases the likelihood that they’ll abandon their cart. We’ll explain the key new features in the WooCommerce update and how to safely implement them on your website.

What new optimization features does WooCommerce 10.9 include?

Quick answer: WooCommerce 10.9, released on June 23, 2026, optimizes checkout speed by delaying the creation of order drafts in the database until the moment of payment. It also includes a native email diagnostics system in the admin panel.

Database Optimization and Faster Checkout

The main technical improvement in this version focuses on reducing storage resource consumption on your server. Previously, the system created a draft order record in the database as soon as a user added a product to the cart. This resulted in hundreds of orphaned and useless data entries if the customer did not complete the purchase, slowing down the admin panel and the checkout response time.

With WooCommerce 10.9, user registration is deferred until the buyer clicks the "Checkout" button. This optimization keeps the database free of unnecessary information, ensuring that the shopping cart and checkout form respond instantly. For a local small business, this translates to a smooth browsing experience that helps retain visitors and improves sales conversion.

In addition, a minor update (10.9.1) was released on June 24 to resolve a specific compatibility issue. This minor update fixed communication errors with the standard credit card payment gateway. By updating, you ensure that customers do not encounter transaction errors when processing their local payments.

Native email logging for easy technical support

Another notable improvement is the inclusion of a built-in tool for tracking emails. You no longer need to rely on external, unreliable add-ons to check why a customer hasn’t received their purchase receipt or shipping confirmation. The system now logs email sends and their results directly in the admin panel under the “Status and Logs” menu.

This feature allows you to diagnose deliverability issues in seconds. If you notice that your company emails aren't reaching their recipients, you can check whether your web domain's SPF and DKIM records are configured correctly. By resolving these issues from the dashboard, you ensure consistent and reliable communication with your customers without overloading your WordPress site.

Step-by-Step Guide to Troubleshooting Your Corporate Email

To get the most out of the new email logs section, follow this quick tutorial:

1. Go to the records section: Log in to the WordPress admin panel. Go to the sidebar and select WooCommerce, then click on Status and go to the tab for Records (Logs).
2. Filter by recent posts: In the log file menu, look for files with the prefix emails. Open it to view a detailed list of order confirmation messages or invoices that have been sent.
3. Check the shipment status: Each log entry will show you the destination address and the status (sent or error). If you notice recurring errors with servers such as Gmail or Outlook, the problem lies with your domain authentication.
4. Update your domain records: Log in to your web domain's control panel and set up the standard authentication signatures (SPF and DKIM). This verifies your identity as the sender to the rest of the world, preventing your emails from ending up in the spam folder.

Audit and Resolution of Deliverability Issues

If you notice email issues in the dashboard, the problem is usually caused by outdated DNS records at your domain registrar. Major email providers around the world have tightened their acceptance policies to combat phishing. If your domain isn’t signed, their servers will silently reject emails from your store.

To resolve this, you need to check three key record types in your domain's DNS settings: SPF, DKIM, and DMARC. The SPF record specifies which servers are authorized to send emails on behalf of your domain. DKIM adds a cryptographic key that verifies the email wasn’t tampered with in transit, and DMARC defines what to do if any of the previous checks fail.

Updating these settings helps ensure that your quote, order, and invoice emails arrive in the main inboxes without any issues. Configuring these protocols at the infrastructure level ensures smooth communication with your customers and reduces friction in the sales process.

Manual Cleanup and Optimization of Your Store's Database

Over time, online stores accumulate hundreds of obsolete session and configuration records that aren't automatically deleted. This overloads your server's database tables, increasing TTFB and slowing down the checkout process.

To resolve this, we suggest using WordPress’s built-in maintenance tools or lightweight plugins to clear expired transient records (transients) and optimize the indexes on your system tables. Performing this maintenance regularly ensures that the database engine processes your customers’ purchases quickly.

This task should be scheduled periodically outside of peak traffic hours. Keeping the database clean prevents fragmentation and ensures consistent load times. Additionally, reducing the physical size of your tables shortens the time required to complete backups, making weekly backup tasks easier and protecting your business from unexpected IT failures.

In addition, we recommend that you periodically check the disk space used by your WordPress database in your server's control panel. If you notice unusual growth in the transactional tables, please contact our technical support team for assistance with advanced physical optimization.

Keeping the database free of orphaned records prevents unexpected errors when saving shopping carts and ensures that payment gateways process each transaction successfully. This preventive optimization routine is the best way to ensure the continuity of your e-commerce business.

Preventing Database Bloat Through Automated Maintenance

A database overload is usually caused by the excessive storage of orphaned temporary records generated by queries from payment gateways or third-party plugins. In high-traffic online stores, these records expire within seconds but remain in physical storage, preventing the SQL engine from indexing the tables quickly.

The best way to solve this is to schedule automatic maintenance tasks at the server level that run database cleanup commands periodically in the background. This ensures that the table wp_options Keep it compact to prevent your checkout performance from deteriorating and ensure the site remains fast for all your regular visitors.

Checklist for Safely Updating WooCommerce

To ensure smooth WooCommerce core updates, it is essential to follow a structured technical protocol. We recommend following these steps:

1. Perform a full backup: Before clicking the update button, make sure you have a recent backup of your files and your WordPress database.
2. Enable the staging environment: Deploy an exact duplicate of your website to a restricted-access test URL so you can make changes there first.
3. Disable temporary cache plugins: Clear the page and homepage cache to prevent outdated pages from being served during the update in the test environment.
4. Run the WooCommerce update: Update WooCommerce to version 10.9 and perform the recommended updates to the store's database.
5. Test the entire purchase flow: Place a test order in the staging environment and verify that the local payment methods in Colombian pesos are working correctly.
6. Check the email log: In WooCommerce > Status > Logs, verify that the order confirmation emails for the test order are sent successfully.
7. Synchronize changes to production: Once stability has been confirmed, deploy the update to your live website during off-peak hours and actively monitor user behavior during the first few hours after the update.

The stability of your online store is your most valuable business asset on the internet. Be sure to host your project on high-performance servers optimized for WordPress, equipped with fast storage and advanced memory, to support the growth of your online sales and ensure your success.
