Acceptable complaint and spam rates for EmailOctopus Connect
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.
