wp_mail() is not working on server

I am breaking my head from last 1 hour but not getting any idea that what’s going wrong with my code…

I am developing my own plugin and I am using wp_mail() function for sending mail in that but it’s not sending mail it seems.

I tried to use PHP Mailer which is working fine but I want to use wp_mail().. this is my code..

  $from = "abc@gmail.com";
    $headers[] = "From:" . $from;
    $send = wp_mail("myemail@gmail.com", "hiii", "hiiii",$headers);
      if($send) {
          echo "send";
        return false;
       } else {
           echo $send;
        return true;
       }

Can any body help me to figure out my mistake… I am testing it on my server only…

Thanks in advance.

Since PHP Mailer is working fine do you have the same credentials setup for wp_mail? If you’re using an authenticated SMTP for PHP Mailer then you’ll possibly need a plugin to get the authentication into wp_mail. There are a few different ones that all work but one is https://wordpress.org/plugins/wp-mail-smtp/ for example.
