I run cold for an agency. We've used Hunter, NeverBounce, and ZeroBounce. This matches them on accuracy and is meaningfully cheaper at our volume. Switched everything over in March. Priya Nair

Common Questions About berkeley.edu
Is berkeley.edu a disposable or temporary email provider?
No. berkeley.edu is not a disposable email provider. It is classified as Education Email operated by University of California Berkeley and addresses on berkeley.edu are persistent rather than throwaway. Mail sent to a valid berkeley.edu mailbox reaches a real recipient.
How do I verify if a berkeley.edu email address is valid?
The fastest way to verify a berkeley.edu email address is to use our free email checker. Enter any @berkeley.edu mailbox at the top of this page and our system performs a real-time SMTP handshake against berkeley.edu'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 berkeley.edu email exists without sending a message?
Yes. Our real-time email verification API connects directly to berkeley.edu'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 berkeley.edu mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for berkeley.edu?
berkeley.edu currently publishes 5 mail exchange (MX) records. The primary MX is aspmx.l.google.com, which is the first server contacted when other mail systems try to deliver email to a berkeley.edu 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 berkeley.edu.
Does berkeley.edu use SPF, DKIM, and DMARC email authentication?
berkeley.edu 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 @berkeley.edu is genuine, and berkeley.edu's DMARC policy of 'reject' instructs receivers how to handle messages that fail those checks.
Why do emails to berkeley.edu bounce or get blocked?
Bounces from berkeley.edu 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 berkeley.edu'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 berkeley.edu's receivers trust you.
How can I verify a large list of berkeley.edu email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of berkeley.edu addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, berkeley.edu 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 berkeley.edu email addresses?
Yes, with normal hygiene. berkeley.edu is a legitimate email service and signups from @berkeley.edu 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 berkeley.edu by default.
What email format does berkeley.edu use for usernames?
Most berkeley.edu mailboxes follow common patterns like first.last@berkeley.edu, firstinitiallast@berkeley.edu, or first@berkeley.edu, but the actual local-part rules depend on University of California Berkeley. The only reliable way to confirm whether a specific @berkeley.edu 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 berkeley.edu risk score calculated?
The 0-to-100 risk score for berkeley.edu 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 berkeley.edu score is recomputed on every audit so it always reflects the live state of the domain.
