how to pass session id in the email notification - laravel

Am trying to login users through a link in email sent after registration.

In my registration method I have the following code

$user_id = $user->id;
    Session::put('userId', $user_id);
    Auth::login($user_id);
    Auth::attempt(['email' => $request->email, 'password' => $request->password]);
    $email = $request->email;
    if($email != ''){
        $send = app()->make(\Snowfire\Beautymail\Beautymail::class);
        $send->send('emails.welcome', compact('r_message', 'username', 'passwordcode', 'user_id'),
            function($r_message) use ($email, $username) {
                $r_message
                    ->from('adun@demovalley.com')
                    ->to($email, $username)
                    ->subject('Welcome to Admiralty University!');
            });
    }

while I passed the session like this on the like

<a href="">Click here</a>

but I get this error message.

 ErrorException (E_ERROR)
 Route [jamb/66] not defined.

How can I make this to work Thanks in Advance
