Email Marketing for Multisite | WordPress.org

Hello! I am looking for recommendation for email marketing plugin/program for our multisite install. We use multi site to manage our spa and retail business, separate businesses but parallel users. We would like to be able to send emails to users across network but also segment users based on the subsite for more niche promotions. I am looking into Mailpoet and Newsletter, do they have these capabilities? Any recommendations? Thank you in advance for any assistance.
