Apple Intelligence generates an AI summary of every email before the subscriber opens it. A second summary appears inside the email when they tap Summarize, immediately above the Unsubscribe button. Rolling out since October 2024, affecting a growing share of every email list.
AI replaces the sender's preheader with a generated summary. The subscriber reads the AI's version before deciding to open.
When the subscriber taps Summarize, an AI paragraph appears immediately above the Unsubscribe button. One tap. Permanent.
