new_network_admin_email_content filter

So, you’re diving into WordPress hooks, huh? That’s awesome! Hooks are like the secret sauce that lets you tweak WordPress without touching the core files. Today, we’re talking about the new_network_admin_email_content filter. It’s a handy one that lets you customize the email content sent to the network admin when their email address is changed.

To use the new_network_admin_email_content filter, first, you gotta register it using add_filter. Just drop this code into the functions.php of your active theme or, even better, a custom WordPress Plugin. At WePlugins, we always recommend the plugin approach. It keeps your tweaks safe during theme updates.

If you ever need to remove a filter, just use remove_filter to yank out the new_network_admin_email_content filter.

• $email_text: (string) Text in the email.
