Hi everyone,  
How can I filter URL Field before the email action?

Example:

URL: [https://discuss.elastic.co/](https://discuss.elastic.co/)

URL\_FILTER: [https://discuss](https://discuss)[.]elastic[.]co/

I'm not sure what you are referring too, but if `URL` is a field obtained from the input query, you can use a scripted field using painless to process the field before it gets passed to the email action. In the email action simply use the scripted field instead of the actual one.
