I've configured Amazon SES and obtained the first level of increased sending rate. So my limits are now 10,000 emails/day, 5 emails/second. My question is: do I need to enforce those rates within my own application (i.e. ensure no more than 5 emails are sent to the SMTP server per second) or can I rely on the server queuing any mail beyond the rate and sending it with a delay?
Of course, I recognise the need to still average out to those rates, but I have a function in my app that sends out ~ 1,500 emails in a 'batch', and I just need to know if I need to throttle it, or if I can just let it run through as quickly at it can.
