Trigger an email if time left estimate is more than 50%

[Umid Baratov]

I have 2 fields: Original Estimate and Time remaining in each JIRA ticket. 

I need some help with creating a rule. What I need us an automated email if Time Remaining triggers an email if it is more than 50% from Original Estimate.

Any help is appreciated.

@Alexander Pappert what component do you use to add the "if time spent / original estimate > 0.5" part?
