The trust reason is theoretical - in practice, I would trust most decently large services especially for unimportant marketing emails (main use case).

My primary motivation in doing this was to learn to use AWS and Serverless framework and also because I really enjoy working on pet projects :)

Could you explain why email isn't trusted? It's encrypted (vs SMS) so I'd imagine it's a far more secure way of communicating sensitive information (e.g. bank statements or one time passwords).
