When I browse the inbox on iPhones and iPads, I see a short preview of the text below the subject line. Gmail also does the same thing (though I don't know if this works the same way).
Is it some way I can influence what text that should be used for the preview, instead of simply using the first sentence(s) in the mail?
Background: I am updating a newsletter that sends out news stories automatically. Usually, the subject line is identical to the header text, so the preview text is redundant. I want to make it show some of the text of the actual article instead.
