No.
GreatFire: mail.google.com from mainland China is unreliable — 100% of the last 6 conclusive tests showed interference.
Hong Kong and Macao are not in this GreatFire mainland set.
How the options compare
| Option | What reports say | What to do |
|---|---|---|
| Hotel or café Wi-Fi | No | Mainland hotel Wi-Fi is the same reachability set GreatFire measures. Do not wait until the hotel network to open Gmail. |
| Gmail Offline in Chrome | Partially | Help: Chrome only, not Incognito. Enable offline mail at home. Mail sent offline sits in Outbox until the browser is online again. |
| Forwarding set at home | Partially | Help: on a computer, Settings → See all settings → Forwarding and POP/IMAP → Add a forwarding address. Spam is not forwarded. |

Hotel or café Wi-Fi: GreatFire — Is https://mail.google.com blocked in mainland China?
Gmail Offline in Chrome: Set up & use Gmail offline
Forwarding set at home: Automatically forward Gmail messages to another account
Before you fly
Open Gmail in a browser → Settings → See all settings → Forwarding and POP/IMAP or Forwarding → Add a forwarding address. Open the other inbox, click the verification link, refresh Gmail, then select Forward a copy of incoming mail to. Help recommends Keep Gmail’s copy in the Inbox. Save Changes. The Gmail app does not have this screen.

Open Chrome — not Incognito. Go to Gmail offline settings → check Enable offline mail → choose how many days of messages to sync → Save changes. Bookmark mail.google.com. Help: a message you send offline is stored in Outbox and sends when Chrome is online again.

Download PDFs, photos, and tickets from mail to the phone or wallet app on home Wi-Fi. A Docs or Drive link inside an old message still needs those Google hosts.
What travelers get wrong
Pitfalls 1
Turning on Offline in Incognito or in Safari
Help only lists Chrome, and not Incognito.
The assumption was “offline mail is in Gmail, so any browser keeps it.” Help: Gmail Offline is a Chrome window that is not Incognito. Safari, Firefox, and Incognito do not keep that store.
View sources (1)
Use a normal Chrome window at home, check Enable offline mail, and bookmark mail.google.com.
Pitfalls 2
Tapping a Docs link because the old message still opens
A cached message is not a live Google host.
The assumption was “the email is on the phone, so the Doc will open.” GreatFire marks docs.google.com blocked on the same Google host set as mail.
Open the file at home and keep a copy on the phone. The link in the message is not the file.
Frequently asked questions
Is Gmail blocked, or does it just load slowly?
GreatFire labels https mail.google.com from mainland China as intermittent: access is unreliable, and 100% of the last 6 conclusive tests showed interference. That is filtering, not a slow inbox.
Does Gmail work in Hong Kong or Macao?
The GreatFire numbers on this URL are mainland China. Hong Kong and Macao are not in that mainland set.
When did Gmail’s web mail stop loading on the mainland?
GreatFire, 29 December 2014: Chinese users had already been unable to open Gmail’s web interface since that summer. From 26 December 2014 the GFW also blocked large numbers of Gmail IMAP, SMTP and POP3 addresses. That is the 2014 cutover, not a 2026 client test.
Is Google Workspace mail a different product on this trip?
Workspace Help walks users through the same Gmail screens: Settings → See all settings → Forwarding and POP/IMAP for forwarding, and the Offline tab to Enable offline mail in Chrome. Those are Gmail settings, not a separate mainland store.
