YellowLab Stop Core Emails adds a focused settings page under Settings > Stop Core Emails, where administrators can disable selected native WordPress email notifications.
You can manage email notifications for:
<ul>
<li>automatic plugin updates</li>
<li>automatic theme updates</li>
<li>automatic WordPress core updates</li>
<li>available core update notices</li>
<li>new user notifications sent to administrators</li>
<li>user password changes</li>
<li>password change notices sent to administrators</li>
<li>user email address changes</li>
<li>site administrator email address changes</li>
<li>new comments</li>
<li>comments waiting for moderation</li>
<li>critical error and recovery mode messages</li>
</ul>
The plugin does not block updates, user actions, comments, or recovery features. It only disables the selected email notifications.
After activation, open Settings > Stop Core Emails or use the Settings link on the Plugins screen.

Disable WordPress Core Update Email

The simplicity of the plugin helps it be lightweight & easy to use.

That also means the one line of active PHP code that it consists of (it then being what WordPress recommends in its current documentation per https://wordpress.org/support/article/configuring-automatic-background-updates/#disable-emails-via-filter) is likely to continue to work exactly as expected unless WordPress were to completely overhaul its setup regarding this (with there appearing to be no plans for this.) Especially considering it's using a filter so it's even more flexible if things were to change in the future (won't outright break things due to a code error beyond WordPress doing a fundamental change to a core function like add_filter or __return_false & that'd then break the majority of plugins & themes out there [they'd need a good reason for doing so & it appears they obviously have no plans for doing that either.])

Does exactly what it says it does (even 5 years since last update)
