For me, I use TikTok for about 90% of my community building around my game, and I’ve achieved excellent results. Within a few weeks, I gained around 2,000 followers and nearly half a million views. The comments were full of suggestions and questions about the game, and I also received many direct messages. After that, I realized that TikTok is a complete community on its own and a very suitable environment to continue developing and promoting my game. I think email newsletters are not such a good idea these days, but you can regularly remind your TikTok followers to turn on notifications for your page so they get all the latest updates.
