How to insert a line break in a markdown Notification

I'm using Laravel's Notifications system to send a welcome email when users register. Everything works great, except I can't for the life of me figure out how to insert a line break in the greeting.

This is my code:

namespace App\Notifications\Auth;

use Illuminate\Notifications\Notification;
use Illuminate\Notifications\Messages\MailMessage;


class UserRegistered extends Notification
{

    public function via($notifiable)
    {
        return ['mail'];
    }

    public function toMail($notifiable)
    {
        return (new MailMessage)
            ->subject('Welcome to website!')
            ->greeting('Welcome '. $notifiable->name .'!')
            ->line('## Sub heading line')
            ->line('Paragraph line')
            ->markdown('mail.welcome');
    }
}

I want to put a break here ->greeting('Welcome '. $notifiable->name .'!') between the welcome and the name. Anyone know how I can do this? I've tried double space as described on markdown documentation. I've tried using nl2br(). I've tried \n. I've tried <br>. Nothing works.

You can just do following:

public function toMail($notifiable)
{
    $name = $notifiable->name;
    return (new MailMessage)
        ->subject('Welcome to website!')
        ->greeting(new HtmlString("Welcome<br>$name!"))
        ->markdown('mail.welcome');
}

This doesn't require to edit any templates.

First of all, make sure to render the string as HTML in your mail view:

{!! $greeting !!}

As mentioned in the answer above, this makes it possible to use <br> inside of ->greeting().

Nevertheless, it's better to use nl2br(). This renders \n as a new line in the HTML mail as well as in the plaintext mail. (Otherwise the <br> is not rendered in the plaintext mail!)

Note: nl2br() only works with a string in double quotes, not single quotes!

Use it in your notification like this:

public function toMail($notifiable)
{
    $name = $notifiable->name;
    return (new MailMessage)
        ->subject('Welcome to website!')
        ->greeting(nl2br("Welcome\n$name!"))
        ->markdown('mail.welcome');
}

Output as HTML:

<p>Welcome<br> 
Username!</p>

Output as plaintext:

Welcome
Username!

Got it to work. Turns out is was in the markdown where the issue lay because of Laravel's escaping HTML when using {{ }}. You have to prevent escaping by using {!! !!}: Using double curly brace in Laravel Collective

For those interested my greeting line is now ->greeting('Welcome<br>'. $notifiable->name .'!')

and in my markdown template it's

{{-- Greeting --}}
@if (! empty($greeting))
# {!! $greeting !!}
@endif
