In your WordPress admin dashboard sidebar go to WooCommerce > Settings. Then click on the Emails tab. Scroll down below the long list of emails and you’ll see a section called “Email sender options”. That sets the email name and address that woocommerce emails are sent from.

Note however that setting the from email there doesn’t mean that WordPress is authorized be the mail server handling your business address to send emails as that address. Those emails therefore may be marked as spam if you do nothing else.

The best thing to do is use an SMTP plugin to setup email sending through SMTP. A plugin such as https://wordpress.org/plugins/fluent-smtp/ This will let you setup WordPress to use a remote email server like Google, AWS, Microsoft, etc. that is hosting your business email address.

I have no affiliation with Fluent, it’s just the free option availabe in the .org plugin directory that I personally prefer.

Furhter, you may need to setup DNS records for SPF, DKIM and DMARC to authorize sending emails. This can seem overwheleming, but there are a number of online guides to help. https://fluentsmtp.com/dmarc-spf-dkim/
