Gmail’s caching doesn’t keep us from tracking the unique opens, since the pixel must be downloaded at least once, so no worries here. Each time the recipient opens the email, the image is downloaded, which allows us to track opens. The opens statistics are also calculated by using an image: a transparent and unique pixel is placed into the message. The number of recipients based in California should also increase… Open tracking – with Mailjet, everything works as usual You should therefore expect the proportion of “other” user agents to surge. Of course, we are looking for a workaround, but there isn’t much hope. There is no way to bypass these two unfortunate side effects. We also indicate which User-Agent was used to access the email: just like for the geolocation, the fact that Google now sits in between us and the recipient keeps us from obtaining this information. We base this information on the IP address the images are downloaded from. Now, however, because all images are sucked up by Google, any Gmail and Google Apps user will appear to be at Mountain View, in California… Many services (Mailjet included) have the capability to display the geographic location of the recipient when they open their emails. The end of geolocation and user agent tracking Of course, this comes with a few side effects. To bypass this risk, Gmail decided to copy all the images on its own servers, in order to ensure security. Google didn’t display the images to protect its users against malicious content. The recipient had to click to see the full message. This is no longer the case: from now on, all images will be displayed by default. Remember the message below? This is what Gmail was displaying by default, for any email containing images. Our team immediately implemented a workaround. One particular issue was raised: the tracking for multiple opens. There are however a few downsides you should be aware of. This change is excellent news for email marketing. Yesterday, an official announcement by Google gave us the real explanation: the famous webmail will now display all images by default. A few days ago, some observers noted that Gmail was now caching all images contained within emails.
