What actually counts as an AI agent in marketing tools?

My line: does it decide the next step itself? An automation runs steps someone designed in advance, even if one of those steps calls an AI model to write a subject line. An agent gets a goal, picks which tools or actions to use, looks at the result and decides what to do next, and keeps going until it's done or stuck. By that test most of the "agents" in marketing tools right now are automations with a prompt in the middle. Not a bad thing, they're more predictable. Just worth asking the vendor what it can actually do without you approving each step.
