Hi,
Glad you figured it out.
standard ideal for Amazon SES 14 email per/sec rule?
It depends on your server speed. This setting works on an average server, and will send out 150 emails / minute.
But at the same time it will also process 150 emails to place in the queue, rebuild campaigns and segments. It has to be able to do all under 1 minute, otherwise your cronjobs will pile up, and your server will crash eventually.
Please run the command and time how long it takes to run it. If it’s under 1 minute, you are good to go. If it’s more, then adjust the settings.
