Assignees field is not getting any emails, when creating a new issue or when updating an issue.

[Vishal]

Is there any other kind of multiple "assignees" fields that we can use that can sent out emails ??

HI @Vishal ,

Basically there is no field supports Multiple assignees in Jira

But if you want you can create "Multiple User Picker" custom field and use that in your notification scheme
