Many would think, why would they need third party bulk email service if they can achieve this by laravel Queues and Jobs. Here I will show you how you can use sendgrid API to achieve this heavy lifting for you - First, Add the sendgrid dependency to your composer.json file, and later install the dependency using command — composer install
This will connect to sendgrid provider using API key and will perform email sending for multiple users at once in a batch of 1000.Create a file App\Services\Sendgrid.php, and add below content to it.
That’s it, you can put this to testing and you would see this working quick and really easy!
