Currently working as tested with Mailtrack. Thank you.
Used to work well but now I can't see the "crossed red-eye" icon. It used to reassure me that it's doing it's job. Any idea @Omar Qureshi?
Was good, but unfortunately no longer updated or supported. I've just found Email Privacy Protector which seems to better anyway.
This is a great addition to any browser in the age of political ad targeting. Everyone should install it.
Can't see the red eye anymore after switching between my accounts on the same device.
Still great after all these years. Thanks Omar.
I don't actually have a way to verify whether or not this works as intended, but I do see the red icon letting me know that trackers are detected, and it doesn't seem to have any negative impact on the format of my emails.
I have been using this for about 4 days and it has shown which Amazon sellers and their "backers" who is watching where I forward a mail. I like to protect our IP addresses and more. Thank you to the developer and will be more aware now.
please add support to outlook.office.com as well
From a display standpoint, PixelBlock is easy to understand and takes not effort on the user other than a simple install. The reason for the low review is due to PixelBlock clearly not working after basic user testing. I installed PixelBlock on my primary email account; Under a secondary, external account, I installed a free email tracker -- in this case Mailtrack -- and sent my primary account a tracked email; Immediately after opening the tracked email from the primary account, the secondary account received a response that the email had been opened. This was tested 3x for basic consistency. I've emailed the developer (omar.w.qureshi [at] gmail.com) a screenshot showing one occurrence to help their team (as well as clearly describing above with app used); however, I will be uninstalling PixelBlock as it clearly does not work as designed.
