Here’s the code I used inside an HTML block under the existing RSS feed. There’s a whole bunch of inline CSS in there to make it match the style of the other RSS feed. That middle section with all the <table> tags was so the photos showed up correctly in emails (a lot of email services don’t render “max-width” and other basic CSS elements). Below this code I’ll go ahead and post a template.
{% set rec_posts = blog_recent_posts('20346648495', 2) %}
{% for rec_post in rec_posts %}

You can find the blog ID by going to your hubspot blog page, and it’s in the URL at the part where it says “blog=”, for example “blog=20346648495” and that number is your blog ID.
