I have Magento 2.1.5 and would like to know if there is an possibility to send newsletter per customer group.
I reckon you are referring to Customer Segmentation.
CS is a native Magento EE feature but it doesn't come in Magento CE package. You may need to buy a thirdparty extension.
I hope that somebody will develop a Magento 2.1 extension, which allows to send newsletters and price lists, incl. Newsletter template to specific customers groups
Absolutely. Magento marketplace is the best place to check this. Try it here: https://marketplace.magento.com/catalogsearch/result/?cat=8&q=newsletter
