Is usa.gov a valid email domain?
usa.gov 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.
SPF is published and ends with ~all. DMARC is set to reject.

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
usa.gov has a strict DMARC policy (reject): mail that fails authentication is refused, which protects its brand from spoofing and means anyone sending as usa.gov must have SPF and DKIM set up correctly.
