The Gmail for iOS app has received an update that automatically blocks external images in emails from loading. This will help block trackers in emails that load invisible images which help certain email services track whether an email has been opened and viewed or not.
The feature is disabled by default, though you can easily enable it by going into the Gmail app settings. Just select your Gmail account -> Images and then enable the Ask before displaying external images. Gmail has offered this feature on the web and it now bringing the same feature to its iOS client.
You can now choose to be asked before external images are displayed automatically. To enable this for new incoming messages, go to Settings > specific account > Images and select Ask before displaying external images.
This move from Gmail comes after the Superhuman email controversy from July this year in which the service was found tracking when and where emails sent using it were opened. The service used invisible images as trackers in emails sent through it to offer read receipts feature to its users. This led to a huge privacy outcry that eventually led to Superhuman turning this feature off by default. It also removed all location tracking features from its service due to the issue.
