In short: Asks Tencent's own mail server whether a qq.com, foxmail.com or vip.qq.com mailbox exists, without sending anything, after syntax, domain, disposable and role checks. Limit: A valid result shows Tencent accepted the mailbox today, not that anyone reads it.
To check if a QQ Mail address exists, enter it here. The checker asks Tencent's mail server about the qq.com, foxmail.com or vip.qq.com mailbox at RCPT TO, then disconnects before any message is sent. Tencent rejected made-up qq.com addresses with 550 Mailbox not found. on 12 October and 8 November 2026, so a missing mailbox comes back invalid.

How do I check a whole list of QQ Mail addresses?
- Export the list as a CSV or copy the email column; QQ Mail rows and every other domain can go in together.
- Upload or paste it at /verify. The first 100 email checks are free with a Google sign-in, no card.
- For every list after that, Pro includes unlimited email verification. Fair use: the first 100,000 checks a month at full speed, then slower, never cut off.
How do I check a QQ email address?
- Type or paste one address, such as
[email protected]or[email protected]. - Press Check. The tool checks the syntax and domain, asks Tencent's server about a random address that can't exist, then about yours, and disconnects before anything is sent.
- Read the verdict: valid means Tencent accepted the mailbox and rejected the made-up one, invalid means it said the mailbox was not found, risky means the check didn't get a clear answer.
- If it comes back risky, check again later: with QQ Mail that is usually a cut-short check, not a bad address.
Example
- You enter
- One address:
[email protected]. - You get
- Valid when Tencent accepts the mailbox after rejecting a random address; invalid ("Mailbox not found") when it answers
550 Mailbox not found.; risky only when the check gets no clear answer. - Limits
- Five checks a minute per IP address, one address at a time, no account needed.
How do I check if a QQ email address exists?
Ask Tencent's mail server instead of the mailbox. On 8 November 2026 qq.com, foxmail.com and vip.qq.com all published the MX hosts mx3.qq.com, then mx2.qq.com, then mx1.qq.com. On 12 October 2026 the server answered a made-up qq.com address at RCPT TO with 550 Mailbox not found., and through this checker on 8 November it rejected a fresh made-up address the same way, with a link to Tencent's help page.
So a single QQ mailbox can be confirmed: a rejection comes back invalid ("Mailbox not found") and an acceptance valid. Many QQ addresses use the account number before the @, so a run of digits there is normal, not a sign of a fake. The QQ Mail provider page has the full DNS snapshot.
Are qq.com and foxmail.com the same service?
Yes. Tencent's QQ Mail terms cover @qq.com, @vip.qq.com and @foxmail.com mailboxes under one service, and all three use the same mail servers, so the checker treats them as one provider. Group them together when you segment a Chinese-market list.
The same terms let Tencent end service for mailbox accounts left unused for a long time, without naming a period. With no published window, older QQ addresses are best checked close to the send date.
Can I check a whole list of Chinese addresses?
Yes. Sign in and use the bulk verifier for a CSV or a pasted list; QQ rows get the same mailbox check as here, alongside 163.com, 126.com and everything else.
For NetEase addresses, the 163 email checker works the same way. The email checker handles any other domain.
What can this checker confirm at QQ Mail?
Each row is something the check runs on a QQ Mail address, and the result you can get from it.
| Check | Can we confirm it? | Result when it fails |
|---|---|---|
| Syntax (the address is written correctly) | Yes | Invalid |
| Domain and mail server (MX) | Yes | Invalid, with a typo suggestion where one fits |
| Disposable or role address | Yes | Invalid (disposable) or risky (role) |
| The mailbox exists | Yes: QQ Mail answers at RCPT TO (550 Mailbox not found) | Invalid, "Mailbox not found" |
| A temporary reply or timeout | No answer to read | Risky, worth checking again later |
| Someone reads the inbox | No checker can | Use opens, replies or a small first send |
Our checking server offered a made-up address and disconnected without sending, on 12 or 13 October 2026 and again through this checker on 8 November 2026.

- Enter it here. The checker confirms the syntax and mail servers, then asks Tencent's server about the mailbox without sending. It rejects addresses that don't exist, so a missing mailbox comes back invalid.

- Yes. Tencent's QQ Mail terms cover qq.com, vip.qq.com and foxmail.com mailboxes, and on 8 November 2026 all three used the same mx1 to mx3.qq.com servers.
- Does QQ Mail close unused accounts?
- Tencent's terms let it end service for mailbox accounts left unused for a long time, but they don't name a period.
- Is this checker free?
- Yes, five checks a minute with no account. For a whole list, sign in with Google for 100 free email checks, no card, or use a monthly plan.
