Or, is there a way to clone/copy the actions?

Hey there,

You can add multiple recipients to an email alert by separating them with a comma. Here's our email alert setup guide which walks you through the setup:

Let me know if you need any additional help!

I'm looking to re-use the email action/template for scenarios. Is being able to "clone" the alerts on the roadmap for future product enhancement?

I know there's no built-in function to clone alerts, but is there a way to, say, edit a config/XML file to accomplish this?

The alerts are stored in the database which gets a bit complicated once you get in there. The data isn't stored in such a way to make it easy to duplicate entries.
