Do you know of any Google App or Chrome plugin that lets you measure opens and clicks for emails sent through gmail. Gmail Meter gives high level analytics but not those at a campaign level.<p>We have an export feature in http://FlashIssue.com in our product that lets you create a newsletter and send it via Gmail. We want to add some campaign analytics to the campaign?<p>Someone else suggested yesware.com but that doesnt provide reporting either.<p>Is there a reason that nobody has created an analytics package for Gmail. We are finding that users are frequently using Gmail to send personal newsletter campaigns.
