If you write about books in your newsletter, this one's for you: Buttondown now supports Bookshop.org embeds.
Paste a Bookshop.org link into your email on its own line and Buttondown will automatically render it as a rich embed with the book's cover art, title, and author. No configuration, no shortcodes — just drop in the URL.
On the web (like in your archives), we use Bookshop's official widget so readers can browse and buy right from your page. In email (because, well, email sometimes sucks), we pull metadata from the Open Library API to render a clean card with the cover image and details.
Bookshop.org supports independent bookstores with every purchase, so your readers get a nice reading experience and local bookshops get a little love too.
To get started, just paste a Bookshop.org URL next time you're drafting an email. (Looking for something to test with? Try out Lessons in Magic and Disaster).
