YOUR NEWSLETTER HAS TWO READERS NOW
Summary from the TLDR Marketing newsletter
Your newsletter now has two readers: the human subscriber and the AI that may summarize, prioritize, or retrieve your email on the subscriber's behalf. AI summaries in Apple Mail, Outlook, and Yahoo can replace your preview text or condense your content, potentially changing what readers notice and whether they click. A Twilio and Inbox Monster test found that subject lines and live text near the top of an email helped shape Apple's summaries, while images and alt text provided less useful information. Test how your newsletter appears in these inboxes, make your main stories and sponsor messages clear in live text, and measure engagement through multiple signals rather than relying on open rates alone.
