I'm not able to add a Rule to the AWS SES Ruleset

I'm using a personal account for this, so I'm accessing AWS as a root user.

When I try to create a rule to be able to receive emails with my domain I receive an error in an alert bar saying

"You do not have sufficient access to perform this action."

I have already set up my domain DKIM and set the MX Records to my domain. I honestly have no idea what to do.

Edit: It seems like the following request is returning a 403: https://lambda.us-east-1.amazonaws.com/2015-03-31/functions/?MaxItems=100
