How to send personalized emails within email group to subscribers

Is it possible to send a personalized email to an email group.
I am using an email template which have a subscriber_name in it.

{% set u = frappe.get_doc("Email Group Member", subscriber_name) %}
Hi {{ u.subscriber_name }}

It only personalized the name of first email group member and was sent to all.
Consider a list of subscribers as , ,
They all are addresses as Hi Eric. instead of each one getting a personalized name.

Can anyone give any suggestions pleaseā€¦
Thank you
