Removing all the success emails on updating plugins
There is a code or plugin to remove all the e-mails for when a plugin has successfully been updated. I have made a separate tutorial for this aspect: Disable Auto-update emails on success tutorial.
Auto update plugins
Another option for turning on / Enabling updates is to use code that can be added to a code snippet plugin or the functions.php file of the child theme.
/* Enable all major core updates */
add_filter( ‘allow_major_auto_core_updates’, ‘__return_true’ );
/* Enable updating plugins */
add_filter( ‘auto_update_plugin’, ‘__return_true’ );
/* Enable updating themes */
add_filter( ‘auto_update_theme’, ‘__return_true’ );
/* Disable sending email on updates */
add_filter( ‘auto_core_update_send_email’, ‘__return_false’ );
