Yes, you should certainly be sending folks a welcome email, but additive to the welcome email there are probably some high value targets signing up who would justify a personal contact, right? "james.smith@example.com" <-- automatic welcome email "james.smith@nytimes.com" <-- automatic welcome email + CEO quickly tells James that he enjoyed that article on the whatever and that if James has any questions he'd, oh, be happy to hop on a call or whatnot. You can even heuristically figure out who the high-value targets are likely to be and forward that directly to the people who would be writing that email. That's also five minutes of work if you know names, email addresses, or domains corresponding to folks you know you'd like to talk to. But, since you're unlikely to get a bazillion registrations on day one, simply tailing (or having someone sitting in MailChimp and refreshing every 5 / 15 minutes) with a visual inspection is likely to catch enough value to make it worthwhile.
