I run a service that emails users new vulnerabilities custom to their stack on a weekly basis, but I'm finding very limited options out there for good email tracking and analytics. The mail service I use has the basics like opens and link tracking but is there any service out there that can do a bit more? I'm looking for data such as inferring scroll depth, per email address tracking, just wondering what the state of the art is in the space.
I'm a developer who works on a large News website. Our service has remained fairly stagnant for a while but I'm wondering what the ultimate news experience looks like for you, considering modern technology. What are News sites missing?
