Ask HN: Gmail spam filtering suddenly marking everything as spam?
Spam/Filtering Outage Symptoms
- Many report a sudden change: legit emails (USPS, HR, system, newsletters) marked as spam or “suspicious,” sometimes delayed 7–10 minutes.
- “Never mark as spam” and Priority Inbox importance markers appear to be ignored or reset for some accounts.
- Others see the opposite: obvious spam (419 scams, fake package deliveries, phishing about cloud payments, “legal boner tea”) landing in Primary or “Important & Unread.”
- Google’s status page links to a spam-filtering incident; some note banners saying messages couldn’t be scanned, with “Looks/Seems safe” prompts.
Tabs & Classification (Primary/Promotions/etc.)
- Promotions/Updates/Social categorization is widely reported “down”: promotions show up in Primary or aren’t separated at all.
- Some say this has been broken for months; one claim ties tab classification to a toggle that also opts email content into AI training, leading them to turn it off and rely on heavy unsubscribing.
- Another commenter asserts that tie-in “never happened” and was misinformation; a rebuttal says the issue is in court and unresolved.
User Impact
- Missed or delayed 2FA, account verification, HR and school enrollment emails.
- Increased noise in inboxes pushes people to disable notifications, further reducing email’s role for time‑critical communication.
- A few see no issue at all, suggesting the problem may be localized or settings-dependent.
Mitigation Strategies Discussed
- Short term: frequently check spam, mark legit mail as “not spam,” star key senders; some expect Google to roll back a bad model in 24–48 hours.
- Using multiple accounts, Gmail “+aliases,” custom domains with wildcard addresses, and services like “Hide My Email” to track and kill compromised addresses.
- Some disable Gmail spam filtering entirely and rely on local clients (Thunderbird, rspamd, SpamSieve, Bayesian filters) or self‑hosted mail servers.
Views on Gmail & Alternatives
- Several say this outage highlights how exceptionally good Gmail’s spam filtering usually is; others argue it has long been too aggressive with false positives.
- Some see it as a final nudge to migrate to providers like Proton or self‑hosting, for both reliability and privacy, though others note most mail still traverses “big corp” servers.
