SMTP & Email Logs for WooCommerce

SMTP & Email Logs for WooCommerce enhances your store’s email delivery by integrating WooCommerce with authenticated SMTP providers.

Instead of relying on the default WordPress mail function, this extension routes WooCommerce emails through a configured email service provider. This helps ensure that transactional emails such as order confirmations, customer notifications, and status updates are delivered reliably.

The extension also records all outgoing emails in a centralized log so store administrators can review message activity, verify delivery status, and resend emails if needed.

What is SMTP?

↑ Back to top

SMTP (Simple Mail Transfer Protocol) is the standard protocol used by email servers to send outgoing messages.

By default, WordPress uses the built-in PHP mail function to send emails. In many hosting environments, this method may cause email delivery issues because messages are sent without authentication.

Using an authenticated SMTP provider allows WooCommerce to send emails through a trusted email service. This improves delivery reliability and provides a clear record of outgoing email activity.

Once SMTP is configured, all WooCommerce transactional emails will be sent using the selected mailer connection.

Setting up SMTP mailers

To configure your email provider:

• From your site’s WP Admin dashboard, navigate to WooCommerce → Settings → SMTP → Connection.
• Select your preferred Mailer Provider from Connections.
• Enter the required authentication details.
• Click Save Changes.

After saving the configuration, WooCommerce emails will be sent using the selected mailer.

Other SMTP providers

If your provider is not listed, you can configure a standard SMTP connection manually.

• SMTP Password (password to log in to your mail account)

These details are typically available in the provider’s email configuration or account settings.
