You can update your store email in the documents in two ways. Either in the Shopify admin or within the template code.
Change email address in the Shopify admin
If you want to edit or change your store address, you can go to your Shopify admin > Settings > Store Details > Contact information and edit your Sender email. Once this is updated, the app will automatically import the new store address in about 15-30 minutes.
