Has anyone tried automating email development?

I work for a medium/large agency. We have a huge client base and email is starting to become the base of all of our products that we offer our clients. We recently had a 10x increased workload. Instead of hiring a ton of developers to hand code everything, we templated out our products. But still it's not enough to keep the time spent.

We currently use adobe products throughout the agency and I don't see that changing seeing as how we work with designers/copywriteres daily. Has anyone tried automatiion?

We already implemented automation on the design side. They use photoshop and excell to feed in information for graphics. Wondering if this could be done with code.

Any advice is appreciated. Thanks email friends!
