How to make a mailing list with a limit on the number of letters in Laravel?

Question

Laravel

I'm trying to make a newsletter about new announcements.
- 1000 addresses
- smtp limit 30 emails/minute.
Laravel has queues - their main goal is to be able to re-execute if something goes wrong. It’s better not to load all 1000 tasks into the queue for sending emails right away due to restrictions.
1) Of course, there are all sorts of sleep, delay(now()->addMinutes(10)), Mail::later($when, new OrderShipped($order)) and other methods - but do they all load PHP during idle time?
2) You can immediately load all 1000 messages into the queue, but most of them will not be sent and you will have to resend them later.
3) Therefore, it will be most optimal to write the code in such a way as to add 20-30 letters to the queue per minute due to the cron task. Well, then the queue is sent out.
Tell me, did I figure it out correctly or is this splitting into small packets for sending not necessary and can I somehow regulate the number of tasks performed (sent letters) using some settings?

No, they don't load.
You got it wrong. I recommend re-reading the queue documentation thoughtfully. The most difficult way is Rate Limiting .
