When a milestone is created resources are automatically added to the milestone tasks but I am facing issue to send email to the resources. I used "send email" option but if a task has 3 resources then everyone is receiving 3 emails rather than 1 email per user.

Resources to the tasks are added dynamically using workflow rule on task by assigning the user group.in send email recipients list I can't directly choose resources field however I have to choose the user group which I had assigned dynamically < link object > resource fields is showing blank.

Can someone share example of config to send email to task resources and everyone should get only 1 email
