I want something very simple but for some reason i can’t get it working
my extractor works and is shown in the email where
{foreach event.fields field} {field.key}: ${field.value} is used
my extractor name is check\_user
How to use it in the email subject?
${event.fields.check\_user} ??
It seems the docs are under development but im getting crazy not managing something that simple…
Thanks!

Ok a part of my mistake was event.fields
Correct value is ${message.fields.check\_user}.
Then my value shows up in the email body but NOT in the subject…
Is this even possible?
