Suppress SPAM comment notification
Ticking this checkbox prevents comments that have been marked as SPAM by another plugin from triggering any comment notifications. An example of a compatible plugin is Akismet.
Default Email Format
This sets the default format of emails sent out from WordPress to either Plain Text (no formatting) or HTML Formatting. Please note that this applies to all emails sent via WordPress, including those from other plugins.
Enable Content Shortcodes?
Ticking this will enable shortcodes in the post/page/custom post type content to be rendered before being added to an outgoing email notification. Doing so may cause high CPU usage however.
Allow Usage Tracking?
Ticking this will send some anonymous data when certain elements within the plugin are clicked. It’s completely optional.
