"Dynamic" here just means the image is generated or personalized at the moment someone opens the email not a static file you upload at send time. Could be a countdown timer, a live price, a seasonal or motion effect on your product photo, whatever.

The use case I'm thinking about specifically: brands that sell physical products, like tools, outdoor gear, apparel, kitchen stuff, you name it AND run email in-house.

These brands usually have great product imagery but their emails are… static. Same hero image, same layout, every send.

So what happened when you added some effect or interactivity?
