Is it possible to create multi-column newsletters?

Site URL: https://www.unit-12.org/

I've been asked to create a template for my organizations newsletter.

Ideally, my boss wants it to have multiple columns of text side by side (i.e. A main column listing the key stories and a side one listing local news).

However, I can't seem to find a way to make it possible. Any blocks of content I make in the newsletter is always stacked top-to-bottom.

Am I missing anything? Is it really not possible to make a multi-column newsletter on Squarespace?

If so, are there any alternative services to use which can be integrated with Squarespace like Mailchimp?

Thanks.

I'm wondering the same thing - surely Squarespace email marketing has access to 3 column formats right? 

You can use this approach to split form/newsletter into multi columns
