Handling Multiple Authors in a HubSpot Blog

Here's a scenario we ran into recently on a client's HubSpot blog: a post was clearly written by two people, both authors were assigned in the post settings, and yet the live page only showed one name. No error, no warning - just a quietly missing co-author.

If you've ever published co-authored content in HubSpot and wondered where the second byline went, this one's for you.

What's Actually Happening

Here's the key piece of context: multi-author support is genuinely new. HubSpot only rolled it out in late May 2026. Before that, every blog post had exactly one author - so that's how blog templates were built, to read and display a single name.

That timing is the whole reason this catches people off guard. HubSpot updated their own default blog templates to display multiple authors automatically. But any custom theme - and most agency- or developer-built templates, which were written before the feature existed - still pulls from the old singular author field. So when you assign a second author, HubSpot stores it correctly, but the template never asks for it.

In other words, this is a template problem, not a data problem. You assign the authors the same way you always have (post editor > Settings > Author, up to five per post); the second name is already there - your template just isn't looking for it.

Why It Matters

Author attribution does more than hand out credit:

• Each author gets a HubSpot author page that lists their posts - a co-author who never renders never shows up on theirs.

• Co-authored content signals depth and expertise, which matters for how both readers and search engines judge your content.

• If you're investing in thought leadership from multiple people, every contributor deserves to be seen on the work they helped create.

The Fix

If you're running one of HubSpot's stock templates, you may already be covered - those were updated when the feature shipped. This is really for custom themes and the older templates most of us are actually running.

The fix is to swap the singular author field for HubSpot's author list variable, content.blog_author_list, and loop through it. A simple byline looks like this:

{% set authors = content.blog_author_list if content.blog_author_list and content.blog_author_list|length > 0 else [content.blog_post_author] %}
{% for author in authors %}
  {{ author.display_name }}{% if not loop.last %} and {% endif %}
{% endfor %}

You'll want to make the same swap everywhere an author appears: the byline at the top of the post, the author bio block at the bottom, and the author details on your blog listing and related-post cards. Keeping the singular field as a fallback (as shown above) means your single-author posts keep working exactly as they do today.

A Couple of Things to Watch

• Cap the count if you want to. If you only ever want to show two names, limit the loop with {% if loop.index <= 2 %}.

• Mind the avatars. Authors who selected an avatar but never uploaded one return HubSpot's "unnamed" placeholder image, which 404s into a broken icon. Guard the image so it only renders when a real avatar exists.

Final Thoughts

Multi-author support is one of those features that's been sitting in HubSpot the whole time, just waiting on the template to catch up. If you publish co-authored content - or want to start - it's a quick, high-value update that gives every contributor the credit they've earned.
