Breaking images when I print in Chrome. Spaceholder for image but no image.
Works like a charm. Images come through just fine for me
Seems to just break ALL images in my emails.
it works for me
Just downloaded it today and tested it with an account I know has Sidekick but no red eye and confirmed by the recipient that they received a read notification....will be uninstalling
Works well, but now how about Inbox support?
Was awesome, recently started breaking all images, no red eye. Would love to put this back to 5 stars.
Says that there's tracking elements in emails that I know don't have any. They're from other personal email accounts I use that I know have no tracking elements in it. They may have an image in their signature, such as for social media, but this doesn't mean they are tracking my email. Also, most emails that it does find tracking elements, it says the source is "unknown" so it's not very helpful.
As a professional user, it is one of the best tools to block the email trackers, if you know how to use it.
Works great, no problems with images like some other reviewers are seeing
