When you share a Buttondown archive link on Bluesky, it can now render as an enhanced link card carrying your publication's name, avatar, and a themed cover, instead of the plain title-and-snippet Bluesky shows by default.
This is powered by standard.site, a community-built standard for describing publications on the AT Protocol (the network underneath Bluesky). Buttondown publishes a small record to your own Bluesky account describing your publication, plus one for each publicly-archived email — and Bluesky uses those to render the nicer card.
To turn it on, head to Settings → Integrations, open the Bluesky integration, and click Create publication under "Enhanced link cards." From then on, both the links Buttondown auto-posts to Bluesky and the ones you (or your readers) paste in by hand will render as enhanced cards.
A couple of things worth knowing:
- You'll need your Bluesky account connected and your archive set to public — enhanced cards describe your public archive, so they only apply to emails that are publicly archived.
- Bluesky pins a card's contents when it's posted, so this applies to future posts and shares. Links you've already shared keep the card they had.
- The records live in your own Bluesky account and carry only enough to identify each article and link back to it — never your email's content. Disconnect any time and the cards you've already posted keep working.
