Email Cop

I use this for all my local installs. It's so helpful and necessary. We recommend it to all our GiveWP users so they can test their emails on staging or locally without worrying that they'll end up blasting their donors. 

So great and easy and does its job well. Thanks!

A simple WordPress admin tool for inspecting rewrite rules. View a listing of all your rewrite rules, see which rewrite rules match a given URL (and the priorities they match in), or filter by different sources of rewrite rules. Perform a soft flush of your rewrite rules to regenerate them.
<a href="https://github.com/Automattic/Rewrite-Rules-Inspector/" rel="nofollow ugc">Developed on GitHub</a> — pull requests are always welcome. Please leave feedback, questions, bug reports, and feature requests in the GitHub issues.
<h3>Where to find it</h3>
Go to <code>Tools → Rewrite Rules</code> in the WordPress admin.
<h3>URL Tester</h3>
Quickly test any URL (or path) against your site’s rewrite rules:
<ul>
<li>See whether the URL would be a 404 or which rule would match first (the one WordPress uses).</li>
<li>View the list of all matching rules, in match priority order.</li>
<li>Inspect the query variables extracted from the match and the resulting final query WordPress would run.</li>
</ul>
Works with full URLs or paths and automatically handles sites installed in a subdirectory.
<h3>Permastructs</h3>
Browse a table of all permastructs that WordPress is aware of, including:
<ul>
<li>Name — the permastruct key (e.g. for posts, taxonomies, authors).</li>
<li>Structure — the permalink structure pattern used to generate rules.</li>
<li>Description — a human-friendly summary of what the permastruct controls.</li>
</ul>
