Businesses using AWS for email marketing or communications must comply with CAN-SPAM and similar laws or risk account termination on top of regulatory penalties.
AWS's AUP binds all customers โ from individual developers to large enterprises โ to a broad set of prohibited use categories, and makes customers responsible for ensuring their own end-users comply. AWS retains the unilateral right to investigate suspected violations and to suspend or remove access to content or resources without prior notice, which can cause immediate service disruption. If you host applications or services on AWS, you should review whether your own terms of service pass these obligations through to your end-users, as failure to do so creates direct liability under your AWS contract.
