How to send bulk messages using wp mail function?

I was working in custom plugin development. I have created customer table in woocommerce and create form to reminder customer for new offers. I am using wp mail function to send multiple email to customer but its works with single customer mail.

here its my code

form class=formpopup action=# method=post
                            div
                            labelTo/labelinput id=customer_to_mail type=text class=modalform style=width: 70%; value= name=customer_to_mail required/divbr
                            divlabelSubject/labelinput class=modalform style=width: 70%; type=text name=customer_subject required/divbr
                            div class=descrlabelDescription/labeltextarea class=modalform style=width: 70%; height: 150px; name=customer_description required/textarea/divbr
                            input style=margin: 20px auto; display: flex; type=submit name=send-mail value=Send Email
                            ?php
                            $to = array($_POST['customer_to_mail']); //[email protected]
                                    $subject = $_POST['customer_subject'];
                                    $body = $_POST['customer_description'];
                                    $headers = array('Content-Type: text/html; charset=UTF-8');

                                    wp_mail( $to, $subject, $body, $headers ); ?
                        /form

And Js code to automatic give customer email in to field

jQuery(document).ready(function() {
    jQuery('.emlchk').click(function() {
       
        var selectedEmailAddress = '';

                jQuery('.emlchk:checked').each(function() {    // $(':checkbox:checked')
                    jQuery('.checkbox_value').text(this.value + ' ');   

                     var emailAdd = jQuery(#EmailAddressTD_+this.value+).text();

                     selectedEmailAddress = +selectedEmailAddress++emailAdd+;

                });
         jQuery(#customer_to_mail).val(selectedEmailAddress);

    });
});
