Great idea. Maybe its time to put the use axios on the back burner.

That is a great point of first giving something valuable and afterwords receiving in return for your effort. Even that is not always true but at least you have created something that may be valuable to someone.

You can try like this:

return (new MailMessage) ->subject('Test') ->markdown('mail.custom-notification', [ 'logo' => 'https://dummyimage.com/200x60/ccc/000.png&text=DEMO+LOGO', ]);

and in the blade:

x-mail::message

Hello

<x-mail::button :url="url('/')"> Action </x-mail::button>

</x-mail::message>
