@daytonamess Having your own website should always be priority #1, but it never hurts to have an email list too.
My advice would be that even if you don't have immediate plans to send any newsletters, just set up an email sign-up form anyway so people can add themselves if they want. If nothing else, email can be a last resort for reaching people if/when various other platforms fall short.
