I'm in a roughly similar (if lower in scale) situation. I maintain a popular iOS app that frequently gets emails from people confusing my email address with the official support email from the service my app is a third-party tool for. I get emails on the order of maybe 3-4 a week.
I have a TextExpander snippet auto-reply. Takes me maybe 10 seconds to reply to a given email. It's hard to give advice without knowing the rough volume of the emails the author deals with; I can imagine situations where this would be a perfectly viable strategy, or times when even that would be an unreasonable amount of work.
