If you do not want to (or cannot) host your own platform, SendingPros.com is an affordable, hosted option to use with AWS (as well as other SMTP/ESP providers such as Mailgun and Sendgrid or your own SMTP).
I've been in adult mailing and list management for 20+ years and I am always available to help you with set up, warm up, automations, etc. on SendingPros. I can even manage the newsletters for you, if you prefer.
Best of luck! Please contact me with any questions.
