The Custom Fields add-on for Better Notifications for WordPress allows you to add information from custom fields created using Advanced Custom Fields (ACF) from any post type in your notifications.

Both the Free and Pro versions of the ACF plugin are compatible with the BNFW Custom Fields add-on.

You can ‘trigger’ a notification to be sent based on one or more custom fields being updated and can customise the notifications by using the new custom field shortcodes to include the additional post information.
