With roughly four in ten opens happening on mobile while iOS and Gmail dominate inboxes, marketers who skimp on responsive design, readable fonts and sender reputation are simply leaving money on the table, because poor mobile formatting drives rapid deletions and unsubscribes, deliverability and reputation issues send one in five emails nowhere, and although mobile promos can spark purchases those orders tend to be smaller unless every touch is optimized.
