Paul Kincaid-Smith wrote an open letter to Gmail about their experiences with the Gmail FBL and how the data from Gmail helped Sendgrid find problem customers.
I know a lot of folks are frustrated with Gmail not returning more than statistics, but there is a place for this type of feedback within a comprehensive compliance desk.
Late last year Gmail started caching images on their servers, breaking open tracking in some circumstances. This image caching was good for senders, in that images were back on by default. But it was also bad for senders because it broke dynamic content and didn’t allow for tracking of multiple opens by the same recipient.
According to a new blog post by Moveable Ink this issue has now been resolved and Google is respecting cache headers so senders who are using dynamic content or want to track multiple opens can do so.
I’m wondering if people are seeing any changes in open rates now that gmail defaulted to on.
Anyone got any quick feedback?
