5 min readYour Preheader Is About To Be Hijacked
Jay Schwedelson and Daniel Murray open with a startling prediction: within the next six months, 50% of email pre-headers won't be the ones marketers wrote. Instead, AI will extract content directly from the email body and insert it into that prime real estate. The episode focuses on a shift that is already happening quietly in Gmail, Apple Mail, and Microsoft Copilot — and it changes how every email needs to be built.
What AI Summaries Are Actually Doing

AI tools like Copilot (now with 30 million paid users, up 10 million in a single month) scan incoming emails for what the industry calls "live text." This is plain, readable text embedded in the HTML code — the kind of hyperlink text that looks like it came from 1994. The AI then pulls the most important information from that live text and displays it either as a summary at the top of the inbox or directly into the pre-header slot, overwriting whatever the marketer originally wrote.
