@manton Thank you, Manton, this seems to be exactly what I was hoping for. For a long time, I was adding a description to my newsletter posts (i.e. ones with titles), using a JSON data template. Then I switched to putting the description in the first paragraph and styling it differently using the pseudoclass :first-of-type. Unfortunately, that pseudoclass doesn’t seem to be recognized by most email clients. More recently I started to use a real class <p class="description"> for the first paragraph. Unfortunately, that meant that my description was being displayed in the RSS feed as if it was the first paragraph of the post, indistinguishable from the body. But this looks as if it will solve my problems. I’m looking forward to trying it out. Thanks again.
