Laravel 5.1 Newsletter every month with cronjob - php

Question

I want to be able to send an automated email to all my users with the top 5 projects of my application. I wanna do this with a cron job on my server.
I have constructed my function in my Marketing class. I created an artisan command but I just have no idea if my method will work. I have no idea how I can get the data in my variables to send in the mail.
I am not sure if my variable $name, $email, $projects will work in the mail and if the mail will actually be sent every month. I just don't think this code will work. And I don't have time to wait a month to test it out :p
My SendNewslettterCommand:
public function handle()
{
foreach(User::all() as $user)
{
$name = $user->name;
$email = $user->email;
$projects = "a query to find top 5 projects of the week";
$Marketing = new Marketing;
$Marketing->sendNewsletter($name, $email, $projects);
}
}
My sendNewsletter function in my Marketing class:
public function sendNewsletter($name, $email, $projects)
{
// In template content you write your dynamic content if you use <mc:edit> tags.
$template_content = [];
$message = array(
'subject' => 'SP*RK - TOP 5 projecten van de maand!',
'from_email' => 'noreply#spark.com',
'from_name' => 'SP*RK',
'to' => array(
array(
'email' => $email,
'name' => $name,
'type' => 'to'
)
),
'merge_vars' => array(
array(
'rcpt' => $email,
'vars' => array(
array(
'name' => 'NAME',
'content' => $name
),
array(
'name' => 'PROJECTS',
'content' => $projects
)
)
)
)
);
MandrillMail::messages()->sendTemplate('newsletter', $template_content, $message);
}
If this is all correct my next steps would be to register my command in artisan by editing app/start/artisan.php and adding:
Artisan::add(new SendNewsletterCommand);
After this I should my command to my crontab
Is this correct or not?
