I had a Yahoo Group for 8 years and started having problems with it. I then tried Google Groups but it lacked some of the things I needed. I then tried goup.io Free version and really liked it. After a year I switched from free to a pay plan and love it. It allows me to add new members quickly and easily. It really is about what you need in the way of services. But I suggest trying the Free version of groups.io and see how it goes. They make it easy to transfer your group information and data.
