If the SEO By 10Web plugin is not installed in your WP dashboard, go to the 10Web Dashboard and enable the SEO service. In your WP dashboard, go to SEO by 10Web, click on Settings, then to the 404 Monitoring tab. Here you have the option to enable this setting or disable it. When enabled, the not found pages will automatically be added to the redirects list under the Redirects section. You can set automatic deletion of your 404 redirects after 30 days, choose where you want to redirect the 404, the status code you want it to redirect with, and to send an email each time a new 404 has been created. Once you have filled in and customized, click save.
