Store owner does not always want to send a newsletter to every subscriber. They sometimes wish that only some specific group of people should receive the newsletter. So to facilitate an admin with that functionality, we have introduced 'Advanced Newsletter Sender For Magento 2' extension.
Under the Marketing > Newsletter Queue, we have added a new field, i.e., 'Customer Group.' An admin can select the customer group from the drop-down he wishes to send the newsletter. And only that particular group will receive the newsletter email.
This extension will send newsletter to customers created from front-end only. Those customer accounts that are created from admin panel will not receive the newsletter email.
Admin can send the newsletter to a specific customer group.
