In the last episode, sending reminder emails was slow, and I didn’t want the whole request/command to sit there waiting on mail. So in this episode I move that work to Laravel queues and make it very, very fast from the user’s/command’s perspective. I install Laravel Horizon so I can actually see what’s happening with a clean UI (pending, completed, failed), and then I switch my queue connection to Redis because Horizon only works with Redis. After that, I create jobs and dispatch them so the heavy work runs in the background while my command finishes instantly. I also show a super important real-world detail: rate limits. If you fire multiple email jobs at the same time, some providers will throw “too many emails per second” (Mailtrap free plan did for me). So I delay jobs (like adding 1 second or even 5 seconds) to control throughput, and I explain why chunking/limiting matters depending on your provider. Finally, I deploy everything to Cloudways, install Supervisor, and run Horizon as a Supervisor job so it stays alive in production. End result: emails are queued, processed reliably in the background, and you can monitor failures and retries properly.
