My company exists to solve this problem at scale for the web hosting industry. It’s too bad that self-hosting isn’t viable because of IP reputation problems, but it’s a reality that is unlikely to change any time soon. I’d say if you want to continue self-hosting, just let go of the delivery part. Use a service like SendGrid; it probably won’t cost you anything and it’s easy to set up.
