What fields can be used in email body?

I am trying to find somewhere a list of the fields that can be used in the body of an email.

The current use case is to configure the welcome email to include as unique fields:

  • Name
  • Email
  • Membership level

I’ve been trying to find somewhere a definitive list of what fields can be used in emails (e.g. by using %{fieldname} and have it replaced by the data) but I am not sure if this exists, or even if I am using the right search terms for what Discourse refers to these as, because I’m not finding anything!

Thanks in advance!

The only fields that can be used are the ones that are already in the specific message. There is no broad list of general all purpose fields that can be used anywhere.

Интересно, всё ли ещё так? В моём конкретном случае я хочу, чтобы категория отображалась в теле письма, отправленного пользователем (например, %{category}), наряду с base_url (этот параметр работает в site_texts, но, насколько я могу судить, не работает в теле письма).

Заранее спасибо.
