If your first email got stuck in a spam filter, chances are your second one will too. Yes, I agree, companies that are likely to get unsolicited email from current or potential customers should check their spam filters daily, but it's an easy thing to overlook.
What I would do in your situation is call them, and start the conversation with "I sent you an email a couple of weeks ago, and I haven't heard back yet; could it have gotten stuck in your spam filter?" Give them a chance to recover.
Also, being where it is (central Jersey), Anedio could have been without power for a week or more as a result of Sandy.
