Can’t change admin email

I’m guessing you’re referring to the admin email address in WordPress. You can change this admin email address in several ways even without using a confirm email:

• Use phpmyadmin from your hosting control panel. Open the “options” table (has a prefix like “wp_” and change the value of “admin_email” to your address.
• Or go to /wp-admin/options.php. Search for “admin_email” and enter the new address there. Save the form then.
• Or use the plugin: https://wordpress.org/plugins/change-admin-email-setting-without-outbound-email/
