Watcher custom email alert

I am trying to create an email alert using watcher. For advanced watcher options , do we have any sample templates to follow ? I would like to trigger emails when application date does not match with current date.

How can I get application date into watcher payload? can we only use the ctx.* values in our scripts ? Whenevr I use my application parameters it return only null values I used my apm label values to compare the values but they return null..

@anjana1 there are some templates that you can follow. There are other options you should be able to use in your scripts, including painless scripts.
