Initially, Amazon will limit you to sending 10k emails per day and 5 emails per second.
but there is an easy way to request an increase.
Step 1: Login to your Amazon Console like usual.
Step 2: Look on the RIGHT SIDE. there is a text that reads " Request An Increase "
Or you can visit http://aws.amazon.com/ses/extendedaccessrequest/ directly and submit the information.
They just want to know about you a bit more before trusting you with more emails. Just explain to them about your
business. How you get your optins and tell them about how it would greatly impact your business running smoother and you can save money.
