Hi all, I run a news letter with AWS SES and the complaint rate is reaching 0.05%. They expect 0.1% complaint rate. I have received zero complaints email from SES in last 1 months but this rate isn't going down. ALl of my email required double opt-in and ubsubscribe link. I have no idea why this complaints rate isn'g going down and worry I may get suspend. I only send around 15K email per month. AWS support is no helpful because the tech support isn't free and around few hundres dollars a month :(. Any one has experience with using SES and dealing with complaints rate?
