About the e-mail, yes. The company should post the proper addresses on their website, and expects the e-mail to be sent to those addresses. Lets say (keeping it simple) the addresses are: email@example.com
OK, now these addresses are on their website, or maybe there are no addresses on the website.
In the first case, where is an e-mail addressed to "specs needed" or "help" routed? In todays world where companies may receive thousands of e-mails a day, probably to a person that does nothing but reads e-mails all day. You may get an answer in a few weeks. But that person costs money--so the e-mail is routed to another place, the dead letter office, more commonly know as deleted.
In the second place, if the address doesn't pinpoint a specific department, the same thing happens. As I said, when a company receives thousands of e-mails a day, they don't care if a few of those e-mails go unanswered. After all, they have thousands of customers--lose a few here, gain a few there--they don't care.
