We wanted to send our clients a mail conditioning the text to the value of the the property lang. So it will display the text on the right language. We used this syntax as we saw in the following arcticle, and it should work:
Please note that using personalization variables (contact and company variables) within if statements is not currently supported for email in HubSpot. These variables can be used for logic on HubSpot CMS pages and blog templates.
Apologies for the confusion and inconvenience.
While it is not yet possible, adding conditional and looping HubL support to Hubspot emails is a priority for the team.That said, they are not yet at a stage where we can offer definitive dates.
If you haven't already, I recommend subscribing to the Developer Changelog so that you are notified once this functionality becomes publicly available.
