supportEmail.send(to: ["support@test.com"], subject: "Support", from: self) { result, error in
    switch result {
    case .cancelled:
        print("Message cancelled")
    case .failed:
        print("Message failed")
    case .saved:
        print("Message saved")
    case .sent:
        print("Message sent")
