On: Gmail blows up e-mail marketing by caching all images on Google servers

I wonder whether this applies only to the web UI.

I've seen a couple startups that were working on dynamic email marketing - they fed in the content as an image, e.g. a "one-day promotion", but would change the image content server-side for future email opens to reflect current details. I guess that this breaks that functionality.

Such functionality should be broken - my email archive should be a permanent record of what you sent, not something the sender is able to tweak afterwards.

Google isn't new to this whole "caching" thing. I would expect them to respect whatever cache expiration directives the web server provides.

This raises an important point.
