To customize the default email message that is sent to new customers after they sign up, you will need to be familiar with HTML and PHP coding. Please follow the instructions below:
1. Using an FTP program (eg. Filezilla), download the file …/catalog/includes/languages/<language>/create_account.php.
Note: The <language> should be replaced with the actual language you are altering. Also, if you support multiple languages then you may be required to change each of the files within the corresponding language directory.
2. Using a text editor (eg. Notepad), make your edits and save the changes.
3. Upload the create_account.php file back to …/catalog/includes/languages/<language>/ on the remote server.
