Sending Emails with Order Based properties

I tried making a rich text module with a custom property that worked through a custom property called ‘sales_rep’ and ‘sales_rep_email’ in the email as text, and they didn’t show up either. Is it possible to use order properties in emails, or am I missing something?

The HTML text was written like this:

<p>

{{ order.sales_rep }}

{{ order.sales_rep_email}}

<p>

Hi @AWills_123 -
I believe “Order” object is unavailable as a personalization token in HubSpot marketing emails. Please check this knowledgebase article for supported object/property.If you want to achieve this, I recommend creating a custom contact property and setting up workflows to populate its values based on the ‘order’ value. Additionally, use the new contact personalization token in your emails.
Hope it helps. Thanks.

Thank you, I just have one other question, how would I set up this workflow to use the ‘order’ value?
