For email you could self host if you learn a bit about warming up and deliverability, but I agree that’s the only exception where people should just use an online service.
Though for privacy, I do use the custom domain with Purelyemail as the host, but if a site is trashy enough to not allow me to use my email - then I distrust it automatically, and use a Gmail account I don’t care nor use for anything but accepting those email confirmations for account creations, or when stores force me to say an email before adding a coupon or something like that.
