Auto mail notification basis of email ID mentioned in User Story description

[Arvind]

Hello All,

I am trying to do JIRA automation to have email notification basis of email Id mentioned in User story description (abc@gmail.com). I am using below smart values to initiate the email notification to specific person email Id. However failed to do so. Can anyone suggest the workaround for same.

{{issue.description.match("[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}")}}
