Hi

Thank you for your question.

There are three stages to include additional information in both the plain text and HTML versions of the email:

• Modify the file where the email is built, in this case in includes/modules/create_account.php
• Add additional language define statements, in this case in includes/languages/english/create_account.php
• Modify the HTML email template to include additional information, in this case in email/email_template_welcome.html

A step-by-step guide is available - Customise Zen Cart Welcome Email – Add Company Name.

Adjust the information within the language defines and the location of the additional information in the email message as required.

Hope this helps,
Kerrin
