For me, I never respond to e-vites. Instead, I RSVP via an email to the actual person. The Automated Invitation sites are very unattractive to me not for ease-of-use, reasons. I don't use those channels because to do so is not only sending an RSVP to the host, it's also telling the website that you'll be attending, as well as their advertisers, their business partners, and other downstream marketers, etc. Let's not confuse social conventions and etiquette with usage of the Ad Revenue oriented vehicles through which were asked to attend.
