Yes. You can verify any @Nps.gov address in real time with a direct SMTP handshake that provides 99.7% accuracy. Nps.gov is operated by National Park Service, runs 1 mail server, enforces 3 of 3 authentication standards, and is currently responding to SMTP.
Every check returns one of three clear outcomes so you know exactly what to do with the address.
The mailbox exists and accepts mail. Send with confidence, the address is deliverable.
The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.
The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.
nps.gov publishes 1 MX record. The primary mail exchanger is nps-gov.mail.protection.outlook.com, hosted by Microsoft 365, and it is currently reachable and answering SMTP. Mail is routed through these servers in priority order, lowest number first.
| Priority | Hostname | IP | Status |
|---|---|---|---|
| 10 | nps-gov.mail.protection.outlook.com | 52.101.8.50 | Reachable |

Addresses are persistent and real mail reaches a genuine recipient. Individual mailboxes still go stale, so verify each one before you send.
A live SMTP handshake connects to Nps.gov's mail server and asks whether the mailbox exists using the RCPT TO command, without ever transmitting a message. The recipient never sees the check.
Each address runs through 30+ checks including SMTP existence, catch-all detection, role-account filtering, and disposable matching. The same engine has verified billions of addresses since 2012.
Every unverified address is a gamble. Here is what happens when you skip verification and mail a list that has not been cleaned.
People leave companies. Verification flags nps.gov mailboxes deactivated since you collected them.
Expired or full nps.gov inboxes hard-bounce. A live SMTP check catches them before you hit send.
Low bounce rates keep you trusted by nps.gov mail servers and the major mailbox providers.
Verified contacts mean your CRM, lead scoring, and routing all run on addresses that reach a person.
