Is it possible to insert field ids into the subject line when creating email templates? I want to show the user their company (account) id: this works in the body but could we use it the subject? ${case.company?keep_before(' ')}

I use fields in my email templates ie "Your update ${transaction.tranid}"

Great, hopefully, the email subject will accept field values!

You should test it. For transactions using the Email then Preview is a quick way

thanks, it worked!
