  <pre><code>procedure TfrmMain.btnSendClick(Sender: TObject);
  var
    aMail: TJclEMail;
  begin
    aMail := TJclEMail.Create;
    Screen.Cursor := crHourGlass;
    try
      aMail.Recipients.Add('service@blabla.com');
      aMail.Subject := '[IMPORTANT] blablba';
  
      aMail.Body := 'text text text text';
      aMail.Send(True);
    finally
      Screen.Cursor := crDefault;
      aMail.Free;
    end;
