About this Domain
About 126.com
126.com is a free email service operated by NetEase Inc., one of China's largest internet technology companies headquartered in Hangzhou. Launched as part of NetEase's suite of consumer internet products, 126.com provides generous storage, calendar integration, and mobile app access primarily to Chinese-speaking users worldwide.
NetEase enforces SPF and DKIM authentication on outbound mail from 126.com, and publishes DMARC policies to help receiving servers validate message authenticity. Due to the high volume of accounts, 126.com addresses are sometimes targeted by spammers, so messages from verified 126.com senders generally pass standard authentication checks when properly configured.
126.com mail servers employ strict bounce handling and will reject messages to nonexistent addresses with clear SMTP error codes. The service does not operate as a catch-all domain. Senders should be aware that NetEase applies aggressive inbound rate limiting and may temporarily defer connections from unfamiliar sending IPs.
When emailing 126.com users, ensure your sending infrastructure has valid SPF, DKIM, and DMARC records. Maintain clean mailing lists and remove bounced addresses promptly. NetEase may filter messages with excessive links or image-heavy content, so keep formatting balanced and include a plain-text alternative for best deliverability.

Common Questions About 126.com
Is 126.com a disposable or temporary email provider?
No. 126.com is not a disposable email provider. It is classified as Free Email Provider operated by NetEase Inc. and addresses on 126.com are persistent rather than throwaway. Mail sent to a valid 126.com mailbox reaches a real recipient.
How do I verify if a 126.com email address is valid?
The fastest way to verify a 126.com email address is to use our email checker. Enter any @126.com mailbox at the top of this page and our system performs a real-time SMTP handshake against 126.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 126.com email exists without sending a message?
Yes. Our real-time email verification API connects directly to 126.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 126.com mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for 126.com?
126.com currently publishes 4 mail exchange (MX) records. The primary MX is 126mx03.mxmail.netease.com, which is the first server contacted when other mail systems try to deliver email to a 126.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 126.com.
Does 126.com use SPF, DKIM, and DMARC email authentication?
126.com has 2 of the 3 standard email authentication records in place: SPF, and DMARC (policy: none). Adding the missing layer(s) would tighten anti-spoofing protection and improve deliverability for legitimate 126.com mail.
Why do emails to 126.com bounce or get blocked?
Bounces from 126.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 126.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 126.com's receivers trust you.
How can I verify a large list of 126.com email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of 126.com addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, 126.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 126.com email addresses?
Yes, with normal hygiene. 126.com is a legitimate email service and signups from @126.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 126.com by default.
What email format does 126.com use for usernames?
Most 126.com mailboxes follow common patterns like first.last@126.com, firstinitiallast@126.com, or first@126.com, but the actual local-part rules depend on NetEase Inc.. The only reliable way to confirm whether a specific @126.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 126.com risk score calculated?
The 0-to-100 risk score for 126.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 126.com score is recomputed on every audit so it always reflects the live state of the domain.
Is 126.com a valid email domain?
Yes, 126.com is a valid free email domain operated by NetEase Inc.. It provides permanent email accounts to users.
Is 126.com a disposable or temporary email provider?
No, 126.com is not a disposable or temporary email provider. It offers permanent email accounts with standard email features.
What mail server does 126.com use?
126.com uses mail servers operated by NetEase Inc.. Check the MX records section above for specific server details.
Can I send marketing emails to 126.com addresses?
Yes, with proper opt-in consent. Follow email best practices and ensure SPF, DKIM, and DMARC authentication is configured for your sending domain.
How do I verify an email address at 126.com?
Use BulkEmailChecker to verify 126.com addresses via SMTP checks. Verification behavior varies by provider. Our tool handles provider-specific rate limiting automatically.
