Hi, I am trying to send email to about 75,000 subscribers using Maildrill API. For the first campaign, I realised that the sending limits were set to defaults i.e. 100 at a time etc.. so I paused that campaign, copied it, marked previous campaign as sent. Reset the settings to 5,000 at one time and 10,000 in a minute. (I did this Globally as well as client's Group level). But even after doing that, the mails are still sent at really low rate. Server has 8 GB RAM. PHP-FPM settings have been optimised as well. I am on PHP 7.2 and PCNTL is not enabled. Also, one more issue. I even enabled Temporary queue table in the main main_custom.php but that isn't working either. (I do not see a temporary table as mentioned in the article) Any pointers?
