Pro: the weekly summary

In Redirects > Settings > Weekly summary switch on Send the weekly summary and, if you want, write the address in Send to (empty: the administration email of the site). Once a week you receive the addresses that answered “page not found” for the first time, the most visited first, with the page that links to each one and the link to the log. A week without new broken links sends nothing.

Send the summary now shows what it looks like. The summary leaves with the email of your site: if it does not arrive, NOP Mail shows why.
