Aws are spam hosters

On a daily basis, I get a ton of spam emails all with IP addresses that originate on the Amazon AWS network. For months I have emailing the AWS abuse team the headers and spam emails. Does anyone know how someone is able to manipulate the AWS network to do this and also, how to get this to stop? Thanks.

What kind of email protection do you have? Is it self hosted email service or cloud based service like Gmail?

I have a Hotmail account and am not using it through Outlook.

Use hotmail anti spam filter. There is not much you can do when you are not controlling email server.
