I mean this without any intention to be rhetorical, but, how common is sending emails to plan an event? For anyone I meet in real life I either talk to them in real life, message them on discord, or call them on the phone. I've got nothing against email, I use it for a lot of things, but it's just too sluggish for event planning in my experience. Occasionally I might use facebook but that's for big consistent events like hosting a yearly get together because I live closest to a fairly big convention that happens in my city.
