Is there a way for an Escalation service to get data from an event listener when it is triggered?

[Tyler Brown-Jones]

Hi

I am hoping for the escalation server to be able to capture data once the event listener is triggered, so that i can then use this data to write a bulk email of all issues without an Estimate.

I am currently using Jira Cloud and i am well aware of the restrictions this presents. 

Hope someone can help

Tyler.
