I am doing a mail of related products, for each product line I am filtering by product name in a HubDB table, but I have a problem, I cannot operate with the varible line_item, I can only print it on the screen, but I cannot apply filters, compare the variable with another variable
"Please note that using filters on any personalization variables (such as but not limited to contacts, company, and deal variables) is not currently supported for email in HubSpot due to how emails are rendered. Filters can be applied to these properties on HubSpot CMS page and blog templates."
