Ask HN: What's the best way to do a listserv in 2018?

I'm about to start a series of founder events here in Brooklyn, like a monthly get together and happy hour. I wanted to create a listserv-style group for everyone to join. Something where users could bbe given a web destination where they can get a little information about the group, fill out a form to apply, and then manage subscriptions to get discussions (in classic listserv style) or just announcements of the upcoming events only. I know there's Google Groups and Yahoo Groups and Facebook and various social media solutions, but in the spirit of the times I'd like to pick a solution that I have a little more ownership and control of. With that said I don't feel like actually building/coding it. Any advice?
