Don't all mail

Hi

I have created a small plugin to get a notification whenever Tablepress table has been updated but I dont get any mail when I try to implement multiple mail addresses.

My code is:

add_action( 'tablepress_event_saved_table', 'pabrady_tablepress_save_notification', 10, 1 );
function pabrady_tablepress_save_notification( $table_id ) {
  $frontend_controller = TablePress::load_controller( 'frontend' );
  $frontend_controller->init_shortcodes();
  add_filter( 'tablepress_edit_link_below_table', '__return_false' );
  $table_html = do_shortcode( "[table id={$table_id} print_name=true /]" );
  $mail_text = "Tabell med ID {$table_id} har uppdaterats: {$table_html}.";
  $headers = array('Content-Type: text/html; charset=UTF-8');

  $multiple_recipients = array('test1@home.se','test2@home.se','test3@home.se'); 

  foreach($multiple_recipients as $to)
  wp_mail($to,'Tablepress tabell har uppdaterats',$mail_text,$headers);
}

I dont get any error whats so ever but I only get 1 of 3 mail sent to above mail addresses and its no 2 of the 3 I get so I dont understand why the other 2 is not sent or recieved. I have an email log and there I can see all 3 as sent.
No mail is arrived as spam either.

Any idea whats wrong or how the solution should look like?
