How to set Importance of email notification using email script?

[rpoola]

I am using same notification in different scenarios. In one scenario, I need to send notification marking importance as High. I tried below syntax and few other but did not work. 

email.setHeader("Importance", "high");

You would probably need to make two different notifications for this. You can set the importance on the notification record itself:

Thank you for the quick response, Elijah. I understood the above approach works.

I would like to use same notification and set Importance in Email script. Do you know the syntax I can use to achieve that.

I'm not sure that you can do that from there. I also wasn't able to find anything online that said otherwise.

I'm using the script proposed in the solution to this question to send emails:  Forwarding the email to another instance

To that script, I added the line below to mark the send as high importance:

mail.importance = "high";
