如何将wp_mail更改为订阅者电子邮件ID

I am trying to setup a landing page on wordpress with a plugin - Coming Soon CC. It has a subscription box. Every time someone sign up for the newsletter I get an email from wordpress@mydomain.com with the notification. How can I change it in a way that I get a mail from the subscriber's mail id itself instead of wordpress@mydomian.com.In other words that it fetch's and sends a mail from the subscribers email id instead of wp_mail. This is what I found in the plugin files -

/**
 * [ajax_newsletter_subscribe description]
 * @return [type] [description]
 */
public function ajax_newsletter_subscribe() {

    check_ajax_referer( 'cc-cs-newsletter-subscribe' );

    $to_email = $this->get_option('newsletter', 'email') ? $this->get_option('newsletter', 'email') : get_option( 'admin_email' );

    if(filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {

        $sent = wp_mail(
            $to_email,
            __('You have a new subscriber!', $this->plugin_slug),
            sprintf(__("Hello,

A new user has subscribed through your Coming Soon page.

Subscriber's email: %s", $this->plugin_slug), $_POST['email'])
        );

        if($sent) {
            print json_encode(array('status' => 'ok'));
            die();
        }
    }

    print json_encode(array('status' => 'error'));
    die();
}

You can set the email $headers, among which From:

$headers = array();
$headers[] = 'From: ' . $_POST['email'] . ' <' . $_POST['email'] . '>';

$sent = wp_mail(
    $to_email,
    __( 'You have a new subscriber!', $this->plugin_slug ),
    sprintf( __( "Hello,

A new user has subscribed through your Coming Soon page.

Subscriber's email: %s", $this->plugin_slug ), $_POST['email'] ),
    $headers
);
