holy smokes google is going to further grow their monopoly and try to take over the advertising market with this. They'll cache and own even more of your data and keep it out of the hands of spammers - in turn spammers will have to buy into google to get data about you. This isn't for us, this was done to make money off of us.

Google is a corporation. Everything they do is to make money.

The images they're caching aren't mine, anyway, and in many cases they're unsolicited. Sure there's the evil aspect to this (they own advertising), but there is the potential good of obfuscating your actually private data - the IP you check your mail from, when you check it, anything you send back with an HTTP request - from marketers. On solely that note, I'm all for it. But I'm also one of those who like the new Tabs setup, and rarely loaded images for emails from people I don't know.

it does, indeed, send the request when it is actually opened. see: https://news.ycombinator.com/item?id=6895876

/me goes to go find and turn on the "block third party images" feature.

Seems pretty trivial for marketers to work around by making each image request a unique URL per-recipient. Assuming Google's proxy fetches the image when the user opens the email, you could use that technique to find out when a user reads the sent mail. You wouldn't get the IP address like you would with conventional bugging, but you could still find out how many users read the mail and what time they did so.

Mmm, it sounds like Google might deduplicate the images....

I thought that at first too, but to deduplicate, they still need to first issue a request for each, download, and compare. So the requests have already been made, and the marketer received their information.

Holy crap. If I'm reading this right, this basically destroys all pixel tracking, so no more email open stats, no nothing.

Not quite. According to testers in the other thread[1], Google pulls images on mail open. This means marketers will get more accurate email open stats because now the default behavior is to load images. However, they don't get cookies, IP, etc so they lose some of that capability. Not all bad for marketers and spammers. I tried to opt-out of external content in Settings > General but unfortunately it's still loading…

Very interesting. And seems like it doesn't affect most mobile users since they use a default client, for the most part.

I think it caches them the moment the email is sent?

That is only possible if the URL is identical. If senders use unique URLs per recipient, Google could guess at which images are identical based on surrounding e-mail content, patterns in URL components, and/or statistical sampling of some of the URLs, but a 100% accurate deduplication would either require identical URLs or a lot of bandwidth to read 100% of URLs.

If they wait until the user opens the email to cache the image, then it's actually BETTER for marketers.

This essentially allows the marketer to track whether the email was opened by default.

Try again. :)

So instead of my work mailing lists having accurate stats via ye olde tracking pixel, now only google does, which they will sell to their own chosen marketers and clients paying google's rate. This isn't the privacy and common-sense win you think it is.

> which they will sell ...

Citation? I was not aware of this.

Why aren't images and other content included in the email itself? It seems silly to send a link to an image rather than the image itself.

Images are the "ping" marketers use to track opens. So you'd have an image link back to `http://mysite.com/tracking?email=joe@stuff.com` which will alert them that Joe actually opened the email. This can give them a conversion rate: for the 5000 people we emailed, 230 of them opened the email, and 67 actually followed the link back to the site.
