Laravel with Mailgun timed messages - php

Question

I have found a way to delay sending e-mail through Mailgun API. I am wondering if external HTML can be used somehow to include in the mail?
Now I am doing it like this:
$mgClient->sendMessage($domain, array(
'from' => 'XY<webmaster#xy.com>',
'to' => 'XY<xy#xy.com>',
'subject' => trans('content.subject_confirm_event_registration'),
'html' => '<myHtmlCode />',
'o:deliverytime' => Carbon::now()->hours(2)->toRfc2822String()
));
But the problem is when I try anything complex, which has like 100 lines of code, it doesn't look well, and I would like a solution where I can put external file in it so that it looks like this:
$mgClient->sendMessage($domain, array(
'from' => 'XY<webmaster#xy.com>',
'to' => 'XY<xy#xy.com>',
'subject' => trans('content.subject_confirm_event_registration'),
'html' => file.blade.php
'o:deliverytime' => Carbon::now()->hours(2)->toRfc2822String()
));

You can manually render a view by using view()->render().
Illuminate\View\View::render() returns the string contents of the view. It is also used inside the class' __toString() method which allows you to echo a View object.
$mgClient->sendMessage($domain, array(
'from' => 'XY<webmaster#xy.com>',
'to' => 'XY<xy#xy.com>',
'subject' => trans('content.subject_confirm_event_registration'),
'html' => view('some.template', $data)->render()
'o:deliverytime' => Carbon::now()->hours(2)->toRfc2822String()
));
