Can I add the post featured image to a specific RSS feed?

Question

I'm currently using the following code:

function featuredtoRSS($content) {
    global $post;
    if ( has_post_thumbnail( $post->ID ) ){
        $content = '<div>' . get_the_post_thumbnail( $post->ID, 'medium', array( 'style' => 'margin-bottom: 15px;' ) ) . '</div>' . $content;
    }
    return $content;
}
add_filter('the_excerpt_rss', 'featuredtoRSS');
add_filter('the_content_feed', 'featuredtoRSS');

Which does work, but I'm running a few MailChimp RSS emails campaigns and am needing one RSS feed to show the featured image (articles feed) and one where I don't want to show the featured image.

My thought is to do this by category, possibly?

Let me know if more clarification is needed!

Thanks!

WPBeginner has a nice article " How to Create Custom RSS Feeds in WordPress" that addresses this from a manageable perspective.

They cover creating custom feeds, and using theme templates to customize what your feeds publish.

Take a look.
