Proofing HTML5 banners to clients

Hi 🙂 I was just wondering how people are proofing out their HTML5 banner ads?

I know I can upload to a server and give a link, but for many banners this is an inefficient process.

I've looked into AdPiler, Ziflow, Filestate, Review Studio - however these are all quite expensive and have more features than we need, such as commenting and reviewing in the workflow. We have a studio workflow already that isn't to be altered.

I'm just looking for a tool to show HTML5 banners and possibly static eDM mocks, without all the extras and at a decent price point. Does anyone know of something?

Thanks!
