Scenario
You’re the only user who can create posts and moderate comments on your WordPress installation.
You have both ‘Email me when anyone posts a comment’ and ‘Email me when a comment is held for moderation’ options checked.
You get an email about a comment awaiting moderation and you approve it.
The problem is that right after that you get a second email letting you know that a new comment has been posted, which of course you already knew about.
Solution
Instead of disabling email notifications for new comments alltogether, you can use this plugin and not receive the redundant emails mentioned above.

This plugin enables WordPress blogs of any size to deliver and track WordPress notification emails reliably, with minimal setup time and zero maintenance. No more SMTP errors or delivery problems with Postmark!
If you don’t already have a free Postmark account, you can get one in minutes. Every account comes with thousands of free email sends.
PLEASE NOTE: This is not official PostMarkApp Plugin. This plugin is a copy of the Official Postmarkapp plugin which had several critical bugs. The Official Plugin developers have not addressed these bugs for some time now, so I created a new plugin to solve those issues.
Issues fixed(from the official version):
<ul>
<li>Fixed the Connection Timeout bug</li>
<li>Fixed the Fatal Error due to incorrect usage of WP_Error object</li>
<li>Fixed the issue while parsing the headers sent as array to the wp_mail function</li>
<li>Fixed the breaking of plaintext when force html option is selected</li>
</ul>
New Features added:
<ul>
<li>Support for adding Cc, Bcc, and Reply-To headers</li>
<li>Support to filter the arguments by other plugins like its done in the actual wp_mail() function of WordPress</li>
<li>Auto import settings from the Postmarkapp approved WordPress plugin for easy migration</li>
</ul>
Roadmap:
<ul>
<li>Support for attachments</li>
<li>Handling special characters in Subject</li>
<li>Ability for dynamic “From” addresses by verifying from PostmarkApp</li>
</ul>
