How to offer inbox to your customer in php using Sendgrid

To set up email parsing with SendGrid, follow these steps:

1. Create a free account on sendgrid.com.
2. Once logged in, navigate to https://app.sendgrid.com/settings/parse and configure your domain.
3. Ensure that you create an MX record in your DNS with the following details:

• Hostname: mailincoming.yourdomain.com
• Priority: 10
• Destination: mx.sendgrid.net

1. Configure mailincoming.yourdomain.com inside SendGrid and enter the webhook URL.
2. With these steps completed, you can now send emails to any address, such as aaa@mailingcoming.yourdomain.com, and receive the webhook content without any issues.

Be sure the check the box labeled “Post the raw, full MIME message.” when setting up SendGrid.

You can use the following package may be

1. Laravel inbox

Let me explain how to setup sendgrid with laravel inbox package.

Install the package then change the setup as follow

 
return [

    'driver' => env('MAILBOX_DRIVER', 'sendgrid'),
    'model' => \BeyondCode\Mailbox\InboundEmail::class,
    'path' => 'laravel-mailbox',
    'store_incoming_emails_for_days' => 7,
    'only_store_matching_emails' => false,
    'basic_auth' => [
        'username' => env('MAILBOX_HTTP_USERNAME', 'laravel-mailbox'),
        'password' => env('MAILBOX_HTTP_PASSWORD','123456'),
    ],

    'services' => [

        'sendgrid' => [
            'key' => env('MAILBOX_SENDGRID_KEY'),
        ],

    ],

];

Your typical AppServiceProvider should be like this

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use BeyondCode\Mailbox\InboundEmail;
use BeyondCode\Mailbox\Facades\Mailbox;


class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return  void
     */
    public function boot()
    {
        Mailbox::from('{username}@mailincoming.yourdomain.com', function (InboundEmail $email) {
            echo $email->subject();
            echo $email->html();
            echo "Jell";
            foreach ($email->attachments() as $attachment) {
                $filename = $attachment->getFilename();
                $attachment->saveContent(storage_path($filename));
            }
        });
    }
}

Make sure you read the setup wehbook url correctly read the documentation.

the MAILBOX_HTTP_PASSWORD environment variable. The default username is "laravel-mailbox", but you can change it using the MAILBOX_HTTP_USERNAME environment variable. :::

You can then set your MAILBOX_DRIVER to "sendgrid".

Next you will need to configure SendGrid Inbound parse, to send incoming emails to your application at /laravel-mailbox/sendgrid. Use the username and the password that you generated for the URL.

If your application is at https://awesome-laravel.com, it would be https://laravel-mailbox:YOUR-GENERATED-PASSWORD@awesome-laravel.com/laravel-mailbox/sendgrid.

But if you don’t like it or confusing laravel inbox url then you can build something like this

namespace App\Http\Controllers;

use BeyondCode\Mailbox\Drivers\SendGrid;
use Illuminate\Http\Request;
use SendGrid\Client;


class InboxController extends Controller
{
    public function getInbox()
    {

        $content = request()->getContent();
        $content1 =json_decode($content);
        $email = new \SendGrid\Mail\Mail();
        $email->setFrom($_POST['from_email']);
        $email->setSubject($_POST['subject']);
        $email->addTo($_POST['to_email']);
        $email->addContent("text/plain", $_POST['text']);
        $from = $email->getFrom();
        $subject = $email->getSubject();
        echo $from;
    }

}
