    TimFeid\SlackLaravelMail\SlackMailServiceProvider::class,

Config

Add the following config to your services.php config file.

    'slackmail' => [
        // The endpoint to your webhook
        'endpoint' => env('SLACKMAIL_ENDPOINT', 'https://hooks.slack.com/services/..../....'),
        // The driver for which you would like to store emails
        // Drivers are 'cache' and 'file' for now
        'driver' => env('SLACKMAIL_DRIVER', 'cache'),
        // Cache settings, will always use your default cache driver for now
        'cache' => [
            // Remove if you would not like to use cache()->tags()
            'tag' => 'slack-mail',
            // Time you want to keep emails for in minutes
            'ttl' => 60,
        ],
        'file' => [
            // File location you would like to save your emails
            'location' => storage_path('/mail'),
        ],
        // From user for your Slack message
        'from' => 'Emails',
        // Channel you'd like to send your messages to
        // @username to send private messages from @Slackbot
        'channel' => env('SLACKMAIL_TO', '#emails'),
        // Fields you would like to show up in your message
        'fields' => [
            'subject',
            'to',
            'cc',
            'bcc',
            'from',
            'attachments',
        ],
    ],

Dot File (.env)

As you can probably tell, .env is encouraged for a per-environment setup

    SLACKMAIL_ENDPOINT="https://hooks.slack.com/services..."
    SLACKMAIL_DRIVER="cache"
    SLACKMAIL_TO="@username"
    
    MAIL_DRIVER="slack" # Activate slackmail as your mail driver

Route

Add this route to your routes file. The route can be set up however you'd like, but it must have slackmail as the name ->name('slackmail')

    if (!app()->environment('production')) {
        Route::get('/slack-mail/{name}', '\TimFeid\SlackLaravelMail\Controllers\SlackMailController@slackMail')
            ->name('slackmail');
    }

Extending the fields

You'll want to create service provider that extends SlackMailServiceProvider and overwrite the registerSlackFields method.

<?php

namespace App\Providers;

use App\Services\Slack\SlackFields;
use TimFeid\SlackLaravelMail\SlackMailServiceProvider as BaseProvider;

class SlackMailServiceProvider extends BaseProvider
{
    public function registerSlackFields()
    {
        $this->app->singleton('slackmail.fields', SlackFields::class);
    }
}

Example SlackFields class

<?php

namespace App\Services\Slack;

use TimFeid\SlackLaravelMail\SlackFields as BaseSlackFields;

class SlackFields extends BaseSlackFields
{
    public function buildSendgridField()
    {
        return [
            'title' => 'Sendgrid Headers',
            'value' => '```'.json_encode([
                'categories' => $this->message->getCategories(),
                'custom_args' => $this->message->getArguments(),
            ], JSON_PRETTY_PRINT).'```',
        ];
    }
}
