Acceptable complaint and spam rates for EmailOctopus Connect

A complaint occurs when an email recipient marks an email message as spam. When using EmailOctopus Connect with AWS, we recommend keeping complain rates <0.1%.

If you have connected your AWS account to EmailOctopus, we rely upon Amazon as the ESP ( email service provider) to monitor and control the variables of spam. 

Regarding  complaint rates, there is not a definite figure that will result in a ban from EmailOctopus or Amazon SES. Generally speaking though, try to keep these around 0.1% or below for your campaigns.
