Mailgun and Laravel?

Question

Laravel

Good afternoon! I have several questions. To send many identical emails using laravel's mailgun, I simply pass in an array of addresses. Applies to letters that are not personalized. What if I need to send 20-30k personalized emails, the only difference in the email is the username.
Will mailgun block me if I send 20-30k requests to it overnight? Another question is how large an array of addresses can I send along with a letter, are there any restrictions?
Also, if I send 20k messages in a loop, but I do it using queues, can I time out?
I searched on the mailgun site, but either did not see or do not have this information. Thank you!

Answer 1

Regarding limits on simultaneous sending - 1000 recipients per request.

Answer 2

It's best to split around 800 addresses, and send about 40 requests.
