How to Test Your WooCommerce Emails: Insights and Obstacles to Overcome
Blog post from Mailtrap
WooCommerce’s built-in Email Preview feature can help merchants inspect the appearance, subject line, body, and formatting of transactional email templates, but it does not test deliverability, spam filtering, blacklist status, or compatibility across devices and email clients. The guide distinguishes email rendering tests from email-sending tests, emphasizing that both are important for customer-facing messages such as order confirmations and shipping updates. It recommends using the WP Mail SMTP plugin with Mailtrap Email Sandbox credentials to route WordPress test emails into a controlled inbox, where users can review HTML issues, spam scores, and other delivery-related details before messages reach real recipients. It also describes an alternative PHPMailer-based SMTP configuration for integrating the sandbox through WordPress, while concluding that effective WooCommerce email testing should address both visual presentation and reliable delivery.
