AWS End User Messaging adds registration improvements for faster, higher-quality submissions

AWS End User Messaging now makes it easier to complete messaging registrations correctly the first time, with clearer guidance, explicit field requirements, and help avoiding the most common rejection reasons. Registrations ask for compliance evidence such as opt-in proof and sample messages, and submissions are often delayed or denied when that evidence is incomplete or a required field is missed. These improvements give you worked examples, surface exactly which fields you must provide, and walk you through the content that most often causes denials.
