css – Show email template with original woocommerce size

I'm using a customization plugin for WooCommerce emails and I have a problem when I see the emails from my cell phone, it changes the size of the email, it gets bigger adjusting to the screen, and I want it to show up in its original size, I explain myself with two captures:

In the first capture is how I want it to look, and in the second capture is how it looks, from the mobile.

I have to assume that it has something to do with CSS, but I do not know what to edit so that it is displayed in its original size and does not adapt to the screen or is "enlarged".

Thanks greetings.
