Why you have to disable the downloading of images in your mailbox

You may not know it, but by the time you open an email in your inbox, there is a good chance that its announcer will be notified and receive an acknowledgment, not only telling him that you have opened his message, but also the time you read it. How? 'Or' What ? Quite simply because of the images contained in the message.

This technique is nothing new. Called Pixel tracking or pixel-spy, it is very often set up to track you even in your mailbox. It relies on the insertion of the link to an image or an invisible pixel, stored on a remote server, directly in the body of the message. When the message is opened, your messaging application will then download these images from the servers where they are stored to display them in the body of the message.

Without you being informed, the sender of the message receives a notification allowing him to know when the message was opened by the recipient and possibly your geographic location. This precious information is then used to better target future shipments and to feed statistics.

Fortunately, it is possible to prevent this by disabling automatic downloading of images in the messages you receive. In addition to strengthening your protection against tracking, you will save your mobile data if you collect your mail in 4G.

Block email downloads from Gmail

Whether you use the web version or the iOS / Android application of Gmail, you can easily turn off automatic image downloading.

To do this, go to the settings box then in longlet General, access the menu imagery, and choose to Ask for confirmation before displaying external images.

When you open a message, no image contained in the body of the email will be downloaded.

You will have to click on the button View images, just under the subject line of the email, to download the images contained in the shipment.

Block uploading of images to Mail on iPhone

If you are using the native diOS mail client, open them Rglages, and go to the dedicated menu Mail. Then deactivate the option Load images so that these are no longer automatically downloaded when a message is opened.

You can, if you wish, decide to display them by pressing the mention Load all images, displayed at the top of the message.

Then click on Privacy Management Center, then on Privacy Center settings.

Make sure the line Do not download images automatically in HTML email messages is well coch.

If you use Outlook.com webmail, there is basically nothing you can do. On its support page, Microsoft explains that its platform automatically secures the download of external images that may be contained in an email, using an image proxy.
