Email Certain Users Based on Ultimate Member field data?

Hi! Delete if not allowed, but I’m trying to figure out ways to send emails to a subset of my site’s members based on their UM field data, e.g. send an email to all members with Profession listed as Writer, members with State listed as California, etc. I see various services/integrations allow for creating email lists based on user roles, but I’d rather not have to assign dozens of user roles for every profession, location, etc. What platforms exist that can do this or what’s the most straightforward way to do this with a plugin like Newsletter or platform like Mailchimp, MailPoet, etc.?

Thanks!
