Yes. You can verify any @Ca.gov address in real time with a direct SMTP handshake that provides 99.7% accuracy. Ca.gov is operated by State of California, 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.
ca.gov publishes 1 MX record. The primary mail exchanger is state-ca-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 |
|---|---|---|---|
| 50 | state-ca-gov.mail.protection.outlook.com | 52.101.11.12 | 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 Ca.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 ca.gov mailboxes deactivated since you collected them.
Expired or full ca.gov inboxes hard-bounce. A live SMTP check catches them before you hit send.
Low bounce rates keep you trusted by ca.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.
Ca.gov is State of California, registered through get.gov and first seen Oct 1, 1997.
The domain ca.gov is the official web domain for the State of California, the most populous state in the United States. California's state government, headquartered in Sacramento, administers a vast array of public services including education, transportation, environmental protection, healthcare, and public safety for nearly 40 million residents.
As a .gov domain, ca.gov implements SPF, DKIM, and DMARC to authenticate official state communications. California's state government follows CISA guidelines and has adopted strict DMARC policies to prevent email spoofing. Given the state's large population and extensive government services, phishing attempts impersonating California agencies represent a significant threat to residents.
California state mail servers do not operate in catch-all mode. The SMTP infrastructure validates recipients and rejects messages to invalid addresses. The state's email environment employs greylisting, rate limiting, and advanced connection filtering to manage the high volume of inbound messages.
Email deliverability to ca.gov requires complete compliance with authentication standards. California's state email gateways use enterprise-grade spam filtering, content analysis, and sender reputation evaluation. Senders must maintain valid SPF, DKIM, and DMARC records and demonstrate consistent, legitimate sending behavior to reach California state government inboxes.
