I does not make a difference, at least from my point of view. I think those personal emails are warranted if my first contact with a company was human, like I reached out and contacted someone from the sales team. But "personal" responses to an obviously automated process like signup is just dishonest. If the founder responds to support requests - fine. Send me a personal response once I have a support request, but not as a signup confirmation.
