Laravel How to return custom error message for newsletter

Question

I'm using the spatie/laravel-newsletter -package for my laravel -app and I want to make a check if a User already has subscribed for the newsletter. When a user is subscribed I want to return/display a custom error message, like "You have already subscribed" - or something like that, how is that possible?

Here is my check:

    if (Newsletter::isSubscribed(request()->email)) {
        // return custom message here?!
    }

Any suggestions?

You could flash a session variable with the error message and display it in your view :

if (Newsletter::isSubscribed(request()->email)) {
    return redirect('/your-url')->with('errorIsSubscribed', 'You have already subscribed');
}

And then display it in your blade view like so :

@if (session('errorIsSubscribed'))
    {{ session('errorIsSubscribed') }}
@endif
