Remove filter callback: method in class

Question

I need to disable this filter:

$message = apply_filters( 'woocommerce_mail_content', $this->style_inline( $message ) );

The style_inline() function exist in a class called WC_Email. So I tried:

remove_filter("woocommerce_mail_content", WC()->WC_Email->style_inline());

But it was a wild guess and it didn't work.

Link to the full apply_filters code: here

Link to the style_online() function: here

Note that to remove a filter callback from the woocommerce_email_content filter, you first need to have it registered via:

add_filter( 'woocommerce_email_content', ...some-custom-callback... );

but it looks like you're trying to remove the inline styles from the message.

I guess you need the text/html content type, so try instead to override the styles with (untested):

add_filter( 'woocommerce_email_styles', '__return_null' );
