Transactional email and HUBL

juanchi-onlinua — Fri, 14 Nov 2025 19:04:00 GMT

Hi, can HUBL be used in transactional email templates (via a custom module)? I can't find any information about it, and it's not recognizing my conditionals, e.g.:

custom mod: test-hubl

{% set monto_raw = personalization_token('custom.monto_descuento', '') %} {% set monto_str = (monto_raw ~ '')|trim %} {% if monto_str == '' %} No vino monto_descuento {% else %} {% set monto_num = monto_str |replace(',', '.') |regex_replace('[^0-9.-]', '') |float %} {% if monto_num > 1 %} Mayor a 1 {% else %} No es mayor a 1 {% endif %} {% endif %}

Hi @juanchi-onlinua,

Yes, HubL can be used in email in particular when the "programmable email" feature is turned on.

https://developers.hubspot.com/docs/cms/start-building/features/data-driven-content/emails-with-programmable-content

However, the "programmable email" feature is in beta (it has been in beta for at least a few years now), so there have been issues mentioned with this functionality where HubL is not working 100% like it would be in website modules.

Hi @juanchi-onlinua

Yes, you can do this, but the feature is still in beta. Here is the doc link, which can guide you better -
