Custom buttons now work in Markdown mode

Custom buttons have been a Fancy Mode feature since we introduced them back in 2024. But what if you're a Markdown die-hard and still want those nice call-to-action buttons in your emails?

Good news: you can now use custom buttons in Markdown mode too. Just drop this into your email:

<buttondown-button href="https://example.com">Check it out</buttondown-button>

You can add alignment and custom colors too:

<buttondown-button href="https://example.com" align="left" color="#ff6b6b">Left aligned, coral</buttondown-button>

If you've already used custom buttons in Fancy Mode, nothing will look different—we're just tidying up the underlying format the next time you edit an email containing them.
