Creating Scriptable Templates
You can make scriptable templates in a text or HTML editor outside NetSuite, or use the Text Editor on the Template subtab of the template record. If you create a scriptable template outside NetSuite, save it as a plain text (.txt) or HTML (.html or .htm) file.
When updating system email templates (at Setup > Company > Company Management > System Email Templates) you can update the standard scriptable version of a system email template, by editing the template appended with 2.0.
If you want to write your own email or fax from a transaction or entity record, select the template type in the Template Format field, then use the Field Type and Insert Field lists to add fields to your message.
If you use the UK Edition, your business address and VAT number go in the footer of all emails you send outside your company to comply with UK law.
