# Advanced Custom Fields (ACF) by WP Engine

When you use YayMail Pro with [Advanced Custom Fields](https://wordpress.org/plugins/advanced-custom-fields/) plugin (by WP Engine), you can add a custom field into your order and display that information in emails through YayMail.

First, you need to create a Field Group, and note that, in Settings > Location Rules, select Post Type is equal to **Order** as shown in the image below:

After placing an order, you can see these fields displayed in the order:

To add the custom field information to YayMail's template, please select a real order, then select Shortcode > Order Meta and and use those shortcodes accordingly.
