Is northropgrumman.com a valid email domain?
northropgrumman.com has no MX record, so mail falls back to the domain's own address record. Most senders still deliver, but it is a fragile setup.
It is not a free provider and is not on our disposable list, so addresses here usually belong to a company, school or other organisation.
No SPF record was found. No DMARC policy was found either.

What this means for your email list
What this means for addresses at this domain
The domain accepts mail, but whether a given person's mailbox exists depends on that organisation. Company domains often have staff who left, role mailboxes like info@ and sales@, and sometimes catch-all rules that accept everything. Verify the individual address before you send.
Sender authentication
northropgrumman.com has no DMARC policy, so receivers have no instruction on what to do with mail that fails authentication. Large mailbox providers now expect bulk senders to publish one.
