With WordPress 5.5 release you may have experienced new random daily emails you may have been receiving for every WordPress’s self-hosted theme and plugin updates.
Here is how to stop email notification for theme and plugin update:
Copy below code in your domain theme’s functions.php file… It will look something like this…
// Disable auto-update email notifications for plugins. add_filter( 'auto_plugin_update_send_email', '__return_false' ); // Disable auto-update email notifications for themes. add_filter( 'auto_theme_update_send_email', '__return_false' );
Hope it helps,
Thanks & Regards
