“During 2012, our email program for a large national retailer was hit with unexpected and severe bulking issues due to rapid and mysterious changes in inboxing rules of several major email providers. This was an urgent matter as these customers made up nearly 30% of our regular audience. Data Axle’s deliverability team helped us track down and address the causes. Their tests, advice and recommended data scrubs helped us bring our inboxing back up to nearly 100% per email blast. Since then, their ongoing weekly deliverability reports and team member outreach help us maintain our sender reputation and avoid potential problems with bulking and other deliverability issues.”
