Email Preview / Installation
Email Preview is a Utility module for Miva Merchant that lets you preview email templates without having to place a test order or wait for emails to come in.
Install the module, then go to MENU > UTILITIES, ADD REMOVE MODULES, and add "Email: Preview Email Templates" to your store.

After the module is installed, navigate to one of your email templates (USER INTERFACE) and click on the ITEMS tab. Find the "emailpreview" item and assign it. After the item is assigned you will see a new preview tab (or if you don't, click the three dots towards the right hand side of the screen to show more tabs.)
