When working with WordPress email functions, you might come across situations where your site (or a plugin) tries to send an email without a proper recipient. This can lead to errors, wasted server resources, or even deliverability issues.

By default, WordPress automatically checks for updates, installs some updates in the background, and allows file editing directly from the dashboard. While this is convenient for some, many developers and site owners prefer to have full control over when updates happen and who can edit files.
