Whitelist Domain for use in Simulated Phishing

We are running a phishing campaign using GoPhish (running in AWS) and SES. How do I have the domain we are using (setup in Route 53) tagged so that it is not inadvertently reported and blocked as a phishing threat? We have moved our domains from Name Cheap to AWS and they had a process for doing that, but its unclear what that process is with AWS.

Thanks in advance!
