When using the <a href="http://support.wpengine.com/staging/" rel="nofollow ugc">Staging site</a> on WP Engine, you may want to prevent the staging version of your site from sending emails to your site users. This plugin redirects all emails to the site admin.
This plugin should be activated on your Production site. Don’t worry — it won’t do anything unless it is active on Staging site. Once you create a new copy of your Staging site, the plugin will start taking effect there.
This plugin is compatible with WordPress Multisite. If you’re using it in a Multisite environment, it is recommended to either Network Activate the plugin, or follow the instructions for installing it to the <code>mu-plugins</code> directory.

Redirect Emails on Staging

Redirect any emails that are sent by the staging site to the administrator of the site.

To help conserve resources (and because bots don’t care), WP Engine has a custom 404 page for bots. This plugin removes that customization, which allows themes and plugins to serve their own 404 instead.
