mailgun sending emails to spam for company email id

Question

mailgun is sending mails but the mails are going to spam only for company email id and for gmail, yahoo mail and rediffmail its going to inbox how can i fix this? please help.

i have tested for the content of the using mail tester but it but it tells mail is not spam having junk i got 9.2 out of 10

$this->load->library('email');
$config= array();
$config= $this->mail_config();
$config['mailtype'] = 'html';
$this->email->initialize($config);
$this->email->from($template->from_email);
$this->email->to($email);
$this->email->bcc($template->bcc);
$this->email->subject($cust_subject);
$this->email->message($email_content);
$this->email->attach($path);
if($this->email->send()){
$data = 1;
}

i dont understand why it does that only for the company email id , when it works fine for gmail, yahoo mail and rediffmail

A primary reason your messages are getting sorted into spam is the sorting and filtering processes of the recipient's mailserver.
