I suspect a lot of people that never replied would be people the signed up but never got around to trying the product properly or people that immediately saw that it wasn't ever going to solve their problem. Would be interesting to correlate the emails with how engaged the user was after signup. Personally as a user the only time I would try to engage the creators is if the product was very close to my use case but certain aspects didn't work the way I would need. This being for B2B where a potential customer is going to be more engaged, B2C the reply rate to those emails is likely always going to be tiny.
