Seconding https://groups.io/ https://groups.io/ I'm in a number of amateur radio and computing groups there, and it works well. From the creator: "I’ve started three companies. I started ONElist, an email groups service, in 1997, and it was acquired by Yahoo in 2000 (where it was renamed Yahoo Groups). I started Bloglines, an online RSS aggregator before Google Reader was a thing, in 2003, and it was acquired by Ask Jeeves in 2005. I started Groups.io, an email groups service, in 2014, and I still run it." - https://www.wingedpig.com/about/ https://www.wingedpig.com/about/
