How do you get over the Amazon SES sending rate initially? If you have a forum with say 20,000 emails that need to go out for newsletter they reduce the total you can send AND how many you can send per second. I was able to overcome the amount problem but the rate of sending was too fast on Xenforo and always tripped up SES by going too fast. How did you throttle the send rate to go slow enough until SES allowed higher send rates per second?
