We had a few requests to make the call to action button on the cart page more visible. We’re planning to allow further customisations by the plugins settings in future, but we have 2 good solutions for the time being:
You can style the button using css by the class .email-cart-button and style it how you’d like.
Alternatively you can deep link to Email Cart by visiting your Email Cart URL www.your-site.com/cart/#email-cart This means that you can create a custom link to use anywhere on your Cart page, your Top Nav Menu, Right Sidebar or developers can hook on to any location around your site (See the image for a custom example).
Remember you can enable/disable the built-in Email Cart → button here: WooCommerce > Settings > Email Cart > Show on Cart page [tick]
