If you want to display values after sending mail

return View("Contact", contact);

If you want to clear values then Either set values empty manually like contact.Subject = "";...etc and return as above OR you can create new contact object and pass it with view

return View("Contact", new Contact());

You need to pass your view model back to the view at the end of the ActionResult.

return View("Contact", contact);
