How to Fix “Magento 2 Email Template is Not Defined”
Resolving this error requires checking both the Magento admin panel and the underlying file structure. These steps walk through the most effective solutions.
First, verify email template assignments in the admin panel by navigating to Stores > Configuration > Advanced > System > Mail Sending Settings or the relevant section such as Sales Emails. Ensure each email type is assigned a valid template.
Next, confirm the template exists under Marketing > Communications > Email Templates. If it’s missing, create a new template based on the default Magento template and save it.
If the template is defined in code, check the module or theme directory:app/code/Vendor/Module/view/frontend/email
orapp/design/frontend/Vendor/theme/Magento_Module/email
Make sure the file name matches the identifier used in email_templates.xml.
After correcting files or settings, clear cache and recompile:

Understanding Email Template Configuration in Magento 2
Magento 2 handles email templates through a combination of XML configuration, database entries, and admin assignments. Knowing how these layers interact helps prevent future errors.
Email templates are declared in email_templates.xml, which links a template ID to a physical HTML file. The admin panel then assigns that template to a specific email event, such as order confirmation or shipment notification.
If any one of these layers is missing or inconsistent, Magento throws the “email template is not defined” error. Keeping configuration, files, and admin settings aligned ensures stability across environments.
This understanding also makes collaboration with developers more productive, especially during site updates or theme changes.
Best Practices to Prevent Magento 2 Email Template Errors
Preventing this issue is far easier than fixing it after emails stop sending. These best practices support long-term stability and professional ecommerce operations.
-
Always duplicate default templates before editing
This preserves Magento’s fallback options. -
Use clear, consistent template identifiers
Avoid renaming IDs without updating configuration files. -
Document custom email templates
Maintain internal documentation for custom modules or themes. -
Test emails after deployments
Especially after theme updates or module installations. -
Clear cache after changes
Cached configurations are a common hidden cause of errors.
Applying these habits reduces technical disruptions and keeps customer communication reliable.

Sample Email Template Declaration Example
Seeing how Magento defines email templates in code can make troubleshooting much clearer. Below is a simplified explanation of how templates are registered.
A template is declared in email_templates.xml with a unique ID, label, file name, and module reference. That ID must match what Magento references in configuration or code.
If the ID referenced does not exist in this file or the admin panel, Magento displays the “magento 2 email template is not defined” error. Keeping these references synchronized is essential for error-free email delivery.
This clarity helps bridge the gap between technical configuration and business impact.
Formatting and File Structure Tips for Magento Email Templates
- Clean formatting and proper file structure play an important role in Magento email reliability. Small mistakes can cause large issues.
- Email templates should be saved as
.htmlfiles using UTF-8 encoding. Keep markup clean, avoid unsupported CSS, and test rendering across email clients. - Store templates only in approved Magento directories and avoid duplicating template names across modules. Clear naming conventions make long-term maintenance easier and reduce conflicts.
- Well-organized templates support both technical performance and brand consistency.
