I send email from my website using HTML and Ajax, the email is sent sometimes but 90% of the time it doesn't deliver. the messages are not even in the email's spam. this is my code I have it on my website for about 2 years but i never tought it's not working please help :

html : 

       <form id="contact-form" class="contact-form" action="#">
            <p class="contact-name">
                <input id="contact_name" type="text" placeholder="Full Name" value="" name="name" />
            </p>
            <p class="contact-email">
                <input id="contact_email" type="text" placeholder="Email Address" value="" name="email" />
            </p>
            <p class="contact-message">
                <textarea id="contact_message" placeholder="Your Message" name="message" rows="10" cols="40"></textarea>
            </p>
            <p class="contact-submit">
                <a id="contact-submit" class="submit" href="#">Send Your Email</a>
            </p>

            <div id="response">

            </div>
        </form>

Ajax (fichier main.js): 

$("#contact-submit").on('click',function() {
    $contact_form = $('#contact-form');

    var fields = $contact_form.serialize();

    $.ajax({
        type: "POST",
        url: "http://musamr.com/wp-content/themes/musamr/include/php/contact.php",
        data: fields,
        dataType: 'json',
        success: function(response) {

            if(response.status){
                $('#contact-form input').val('');
                $('#contact-form textarea').val('');
            }

            $('#response').empty().html(response.html);
        }
    });
    return false;
});

  • Is, assuming you have setup your php email setting prior to using them... then what does your http server log error file say? – arkascha Nov 14 '18 at 14:56
  • have you looked at your mail logs? Many mail providers these days will just blacklist mail coming off private servers for no particular reason - there is a very good chance your mail is simply being rejected by the recipient. This is especially likely if some is going through but not others. software doesn't typically intermittently fail without some knowable factor - in this case the most likely being the recipient mail server – But those new buttons though..

The mail function is extremely unreliable. You should consider using a SMTP server & a library like PHPMAILER to make integration easier.

phpmailer: https://github.com/PHPMailer/PHPMailer

The mail function will attempt to send but more times than not it will go into the users spam folder or the destination may reject it.

Also instead of that regex you can use filter_var('bob@example.com', FILTER_VALIDATE_EMAIL)
