You may have heard this week that Google made some changes to the way Gmail displays images in their emails. Previously, Gmail would make a request for an image every time an email was opened, but now they temporarily store those images, including the one we use for open tracking.
What does this mean for our users?
To facilitate open tracking in emails, we embed a transparent image (1x1 pixel) in each email, hosted on our servers. When you open the email, JangoSMTP knows that unique image has been accessed, and can then tell the sender their email has been opened. While using cached images is great idea for Gmail, it does create a problem for any Email Service Provider (ESP). Mainly that, with this new image caching system in place, location tracking won't be available for Gmail addresses.
However, there are always two sides to the coin – we have done some tests here at the office and actually are happy to see that open tracking appears to be more accurate with Gmail addresses now. Additionally, this should not affect POP or IMAP mail clients in anyway. For forwarded messages or multiple opens, Google will need to load the image at least that first time before they can cache it. When a customer comes back and re-opens the email, or forwards it to additional address, that’s where you’ll possibly miss some of the tracking, but that doesn't affect that first/unique open.

Remember, this doesn't affect the number of subscribers actually reading your email, it simply makes the unique
opens more accurate.
