Fastmail + 1Password have quite a similar feature, the difference being that you can control it all from your normal email address (the feature is built into fastmail, using JMAP, so that 1password basically calls out to FM and implements a few API calls to generate a random secret email.) Very cool, glad to see more people doing so!
