You can put this in your child theme's functions.php file:

// product suggestion in order mail
function order_mail_product_suggestion($atts) {
    $atts=shortcode_atts(
        array(
            'id' => '',
        ), $atts, 'order_mail_product_suggestion');
    $orderId = esc_attr($atts['id']);
    $order = wc_get_order( (int)$orderId );
    $items = $order->get_items();
    $cat = array();
    $pid = array();
    foreach ( $items as $item ) {
        $pid[] = $item->get_product_id();
        $terms = wp_get_post_terms($item->get_product_id(),'product_cat',array('fields'=>'ids'));
        foreach ( $terms as $term ) {
            $cat[] = $term;
        }
    }
    $uniuqcat = array_unique($cat);
    $uniuqpid = array_unique($pid);
    $html = '';
    $args = array(
        'post_type'             => 'product',
        'stock'                 => 1,
        'post_status'           => 'publish',
        'ignore_sticky_posts'   => 1,
        'posts_per_page'        => '20',
        'tax_query'             => array(
            array(
                'taxonomy'      => 'product_cat',
                'field' => 'term_id',
                'terms'         => implode(',', $uniuqcat),
                'operator'      => 'IN'
            ),
            array(
                'taxonomy'      => 'product_visibility',
                'field'         => 'slug',
                'terms'         => 'exclude-from-catalog',
                'operator'      => 'NOT IN'
            )
        )
    );
    $loop = new WC_Product_Query($args);
    $products = $loop->get_products();
    if ($products) {
        $html .= '
';
            $html .= '

';
            $html .= '';
                $html .= '';
                    $html .= '';
                            $i=0;
                            foreach ( $products as $product ) {
                                if (in_array($product->get_id(), $pid)) {
                                    continue;
                                }
                                $html .= '';
                $html .= '';
            $html .= '
';
                                if (has_post_thumbnail( $product->get_id() )) {
                                    $html .= get_the_post_thumbnail($product->get_id(), 'shop_catalog');
                                } else {
                                    $html .= '';
                                }
                                $html .= '
'.esc_attr($product->get_title() ? $product->get_title() : $product->get_id()).'
';
                                $html .= '

';
                                $i++;
                                if($i==4) break;
                            }
                    $html .= '
';
        $html .= '
';
    }
    // now return the preapred html
    return $html;
}
// register shortcode
add_shortcode('email_product_suggestion', 'order_mail_product_suggestion');

And then call the function in email templates like this:-

// Product suggestions
$order = $email->object;
if ( $order ) {
   $id = $order->get_id();
   echo do_shortcode( '[email_product_suggestion id="'.$id.'" ]' );
}

This will show products from the category where the current order item belongs, and exclude items that are already in the order.
