What Email Marketers Are Saying About Gmail’s Image Serving Change
Google caused quite a stir Thursday with the news that it’s serving images in Gmail from its own servers, rather than from the sender’s servers.
As we reported yesterday, Gmail open rates should become more accurate because images are displayed by default. But other data will go away — the user’s location and user agent, for example.
The initial reaction was largely negative, but now that Google has clarified (a bit of) what is happening, some of the main players in the email marketing industry are taking a more measured view of the image caching change.
Here’s a look at some of the reaction we’ve seen since the image caching change was first noticed last week.
Responsys
In a blog post, Responsys’ Kevin Senne writes that the impact on marketers will depend on how long Google chooses to cache the images:
Multiple opens of an email could record lower, but this depends on how long Google decides to cache the image. If the image is cached, the request will stay internally to Google instead of going back to the sender. This could result in somewhat lower total opens, but except for very rare instances, the unique opens are the important number.
Device and location tracking could be susceptible to some impact since Google now eliminates the original IP address field as they cache the original image. What this means is that as long as the image is cached, the location could show up as coming from the Google image servers in California and not the recipient location as intended. This behavior would go on as long as that image was cached.
Return Path
In a blog post this morning, Return Path’s Melinda Plemel says it’s a trade-off for email marketers — better tracking of unique opens, but a loss of user agent information:
The loss of user agent information has implications that could be huge in a world of multiple devices. Gmail’s announcement indicates the loss of user agent information occurs only on web browser and iOS and Android Gmail apps, but not native apps like iOS Mail.
Despite the loss of certain information, the ability to accurately track unique opens will be of benefit to marketers.
Marketers should be aware that this will mean a jump in opens at Gmail in the short term. Over time, open rates should level off and proper benchmarks can be set.
Silverpop
We heard via email from Loren McDonald, VP of Industry Relations at Silverpop, who says it’s “generally positive” that unique opens will be more accurate at the expense of knowing if an email was opened more than once.
But he points out that the other loss of data could have an impact on location-based and other special email promotions:
The biggest concern is around email marketers who utilize services to serve up real-time content (images) that can be different on successive opens – so things like countdown timers, testing images that change once a winner is determined, etc. Additionally, location data will now show as being wherever the Google servers are that are hosting the cached images. Some marketers will serve up unique content to a recipient – say a special event or promotion at a store close to a recipient using the IP data.
AWeber
We heard via email from Justin Premick, Director of Education Products at AWeber, who says time will be the ultimate judge of Google’s change, but feels that the changes should be seen as a mostly positive thing:
Even if the change causes opens at Gmail to be harder to track, that’s not necessarily a terrible change for most marketers. Opens are an easy-to-get metric, but not the most valuable one. Marketers may shift attention away from opens and to actions like clicks, website activity, and conversions by email subscribers.
Regardless of whether the Gmail change makes tracking opens more or less valuable, all marketers should agree that having images on by default is a broadly positive thing. It creates a better experience for the subscriber – who wants to have to turn on images? – and makes email designers’ lives a bit easier by reducing concerns about designing for images-off.
Lastly, this Gmail change makes email feel safer and easier for the end user, which may make them more inclined to sign up for future email subscriptions.
(Note: AWeber’s email arrived in my In box just as I was publishing the original article, so the above was added shortly after posting.)
Movable Ink
We’ll give the final word to Movable Ink’s Michael Nutt, whose blog post on the change emphasizes that it impacts only a small percentage of Gmail users:
After analyzing our data since the changes were implemented late last week, 2% – 5% of the average enterprise B2C email marketer’s subscriber list is affected by Gmail’s changes, since they only affect recipients that open emails through the Gmail.com desktop client, the Android Gmail app, and the iOS Gmail app.
Not all Gmail users are impacted.
The changes have no impact on Gmail users who access their accounts through Mac Mail, the native Mail app on iOS devices, non-Gmail Android apps, non-Gmail Windows apps, Gmail via Outlook, etc.
Judging by these reactions, it seems that yesterday’s initial frenzy over the change was an overreaction, and that the image caching change won’t ultimately be the negative that many suggested it is.
