We had a sender reputation crisis after a list import went badly. Used the bulk verifier to scrub everything, then plugged the API into our signup form. Took deliverability from 73% to 96% over six weeks. Sarah Knowles · Email Marketing Lead

Common Questions About cbre.com
Is cbre.com a disposable or temporary email provider?
No. cbre.com is not a disposable email provider. It is classified as Corporate Email operated by CBRE Group Inc. and addresses on cbre.com are persistent rather than throwaway. Mail sent to a valid cbre.com mailbox reaches a real recipient.
How do I verify if a cbre.com email address is valid?
The fastest way to verify a cbre.com email address is to use our email checker. Enter any @cbre.com mailbox at the top of this page and our system performs a real-time SMTP handshake against cbre.com's mail servers, confirming whether the mailbox exists, is reachable, and is safe to send to. No email is ever delivered during the check.
Can I check if a cbre.com email exists without sending a message?
Yes. Our real-time email verification API connects directly to cbre.com's mail server, opens an SMTP session, and queries the mailbox using the RCPT TO command without ever transmitting an actual email. The server's response confirms whether the cbre.com mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for cbre.com?
cbre.com currently publishes 2 mail exchange (MX) records. The primary MX is mxb-001bfb01.gslb.pphosted.com, which is the first server contacted when other mail systems try to deliver email to a cbre.com address. The full list with priorities and IP addresses is in the MX Records panel above. MX records tell sending servers where to route email for cbre.com.
Does cbre.com use SPF, DKIM, and DMARC email authentication?
cbre.com enforces all three email authentication standards: SPF, DKIM, and DMARC (policy: reject). This is the gold-standard configuration. It means receivers can verify that mail claiming to come from @cbre.com is genuine, and cbre.com's DMARC policy of 'reject' instructs receivers how to handle messages that fail those checks.
Why do emails to cbre.com bounce or get blocked?
Bounces from cbre.com usually fall into three buckets: the mailbox doesn't exist (5xx user unknown), the inbox is full, or your sending domain isn't authenticated to cbre.com's satisfaction. The fastest fix is to run each address through a free email verifier before you send, and to make sure your own SPF, DKIM, and DMARC are configured correctly so cbre.com's receivers trust you.
How can I verify a large list of cbre.com email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of cbre.com addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, cbre.com catch-all detection, role-account detection, and disposable-domain matching. Results typically come back within minutes and previously-failed addresses on your blacklist are reprocessed for free. For continuous high-volume needs, see our unlimited email verification API.
Is it safe to accept signups from cbre.com email addresses?
Yes, with normal hygiene. cbre.com is a legitimate email service and signups from @cbre.com behave like any other real user. Pipe each address through a real-time email verifier API at the moment of signup to catch typos and dead mailboxes, but there is no need to block cbre.com by default.
What email format does cbre.com use for usernames?
Most cbre.com mailboxes follow common patterns like first.last@cbre.com, firstinitiallast@cbre.com, or first@cbre.com, but the actual local-part rules depend on CBRE Group Inc.. The only reliable way to confirm whether a specific @cbre.com address exists is to run it through a free email verification tool. Guessing patterns will produce a high bounce rate and damage your sender reputation.
How is the cbre.com risk score calculated?
The 0-to-100 risk score for cbre.com combines disposable-domain classification, mail-server reachability, MX record presence and depth, SPF / DKIM / DMARC enforcement, DMARC policy strength, SMTP banner response, and domain age. Lower scores mean safer to send to. Disposable domains are pinned at the high end of the scale. The cbre.com score is recomputed on every audit so it always reflects the live state of the domain.
Is cbre.com a valid corporate email domain?
Yes, cbre.com is the official corporate email domain for CBRE Group Inc.. It is used for internal business communications and is not available for public registration.
Is cbre.com a disposable or temporary email provider?
No, cbre.com is a corporate email domain belonging to CBRE Group Inc., used exclusively by employees and authorized personnel.
What mail server does cbre.com use?
cbre.com uses enterprise-grade mail infrastructure. Check the MX records section above for specific mail server details.

B2B marketing to cbre.com requires proper consent. Corporate domains may use catch-all configurations, so verify individual addresses before sending.
