On October 16, 2026, Google's updated privacy policy took effect. The ad personalization section now includes a caveat: data from Gmail, Google Drive and Google Photos can influence ads if the user has chosen to make it available to other Google services. This does not mean advertisers have gained access to your inbox or photo library.
- When: the policy is effective October 16, 2026.
- How: only with connected apps and personalization enabled.
- Who gets the data: advertisers do not. Google uses the context inside its own systems.
- Sensitive categories: race, religion, health and sexual orientation remain excluded.
What exactly changed
The policy used to contain a simple promise: Google does not show personalized ads based on content from Drive, Gmail or Google Photos. It now adds an exception:
"We don't show you personalized ads based on your content from Drive, Gmail, or Google Photos, unless you choose to make data from these services available to other Google services that support personalized ads."
Formally, that is one clause. In practice, it opens the door to a scenario Google is already building through Personal Intelligence: a user connects Gmail and Photos to AI search, and context from those apps helps shape answers and, by extension, ads. This is not about ads inside the inbox, but about which ads Google shows across its services.
| Question | Before October 16 | After October 16 |
|---|---|---|
| Can ads be personalized using Gmail, Drive and Photos | No | Yes, if the user connected the apps to Google services |
| Do advertisers get access to the content | No | No |
| Are sensitive categories used | No | No |
| Is there a new Google Ads targeting option | — | No |
Where Personal Intelligence fits
Google launched Personal Intelligence in January 2026 as an opt-in feature for Gemini and AI Mode. It can connect Gmail, Google Photos, YouTube and Search so the assistant understands context better: finding a booking in email, trip details in photos, past purchases. Connections are off by default, and the user chooses which apps to link.
That is the route the new policy language refers to. When data from Gmail or Photos is made available to a service that supports ad personalization, Google may use derived signals — summaries, excerpts, inferences — to make answers and ads more relevant.
Important limits:
- The feature is not available to everyone: it is a beta for personal accounts of users 18+, not for Workspace business, enterprise or education accounts.
- According to The Next Web, at the time of publication Personal Intelligence was not available in the EEA, Switzerland, the UK or Nigeria. Availability depends on the country and account.
- Connecting is voluntary. Users can disconnect apps, but Search Services History may retain data already collected.
What Google says about ads
Google's help centre gives a direct answer:
"Ads will not be based directly on your Gmail inbox or your Google Photos library. If you connect your content apps, Search may reference summaries, excerpts and inferences from these sources to personalize your experience. That same info may be used to show you ads."
The difference between "directly" and "indirectly" matters here. Google does not hand emails or photos to advertisers and says it does not build an ad on the contents of the inbox as such. But derived signals from connected apps can influence which ad is shown.
Google also stresses that ads remain tied to the query, the context of the response and the user's interests. Sensitive categories — race, religion, health, sexual orientation — are not used for personalization. Advertisers do not receive the content, name or email address.
What it means for targeting
For a media buyer, there is no new button. Google has not announced an audience of "people with Personal Intelligence enabled", targeting by email subject or access to photos. This is a change in ad personalization, not in audience selection.
What may change:
- Ad relevance. A user with connected apps may see more contextual products and offers. That can affect CTR and conversion, but it is not directly configurable.
- Differences between users. The opt-in audience may behave differently, but you cannot isolate it in the ad account.
- AI Mode and search. In scenarios where the answer is built on connected context, ads may be closer to the conversation. The effect on classic search campaigns is not guaranteed.
- Reporting and attribution. Google has not announced new reports or parameters. A causal link to the policy change cannot be proven from the numbers.
For e-commerce, this is more about the quality of personalization than a new targeting source. For lead gen and regulated verticals, even more so: sensitive categories remain off-limits, and advertisers get no data. Anyone promising "Gmail targeting" is not describing a new Google Ads feature.
If you are just starting, the basics of campaign setup are in the Google Ads beginner guide. For context on AI search and its effect on traffic, see the Google AI Mode breakdown.
Risks and limitations
- Headlines run ahead of the facts. "Google reads your email for ads" sounds scarier than opt-in and derived signals. But the change should not be downplayed either: the policy really did get broader.
- User trust. The louder the story, the more people may turn personalization off. For advertisers, that could mean less signal, not more.
- Retention after disconnect. Disconnecting an app does not delete data from Search Services History; Google warns that the history may persist.
- Sensitive inferences. Google prohibits the use of sensitive categories, but users may not trust the models to be careful. Advertisers certainly must not try to work around those limits.
- Regulation. The feature is not yet available in the EEA, the UK or Switzerland; scrutiny and consent debates are likely.
- Unpredictability. Personalization can be wrong or over-personalized. Ads do not automatically get better — they get different.
What advertisers should do
- Do not rebuild campaigns. There are no new targeting options; drastic changes based on one policy update are not justified.
- Do not promise clients "access to Gmail". The data is not passed to advertisers, and no such setting exists in Google Ads.
- Audit consent and first-party data. Especially if you upload customer lists or work with sensitive categories.
- Watch performance by geo and campaign type. But do not attribute every fluctuation to the policy: auctions, creatives, seasonality and moderation also matter.
- Check your own settings. Data & privacy → Personalization settings → Manage Personalized Recommendations in Search Services → Connected Content Apps. This is privacy hygiene, not a media tactic.
- Update client explanations. Keep the distinction clear: Google uses context internally; advertisers get settings and reports, not inboxes.
FAQ
Does Google now read my email to show ads?
Not in that form. The policy allows data from Gmail, Drive and Photos to be used if you connected those apps to Google services with personalization. Google says ads will not be based directly on the contents of your inbox or photo library.
What changed on October 16?
The policy added an exception: the ban on personalization using Gmail, Drive and Photos does not apply if the user made the data available to other Google services that support personalized ads.
Is it on by default?
No. Connecting apps in Personal Intelligence is opt-in. The user chooses which apps to link and can disconnect them.
Will advertisers see my emails or photos?
No. Google says advertisers do not get access to Gmail, Drive or Photos, or to the user's name or email address without permission.
Is there Gmail targeting in Google Ads?
No. No new audiences, settings or reports have appeared. The change affects ad personalization, not audience selection.
Which countries does it cover?
Personal Intelligence availability depends on the country and account. According to The Next Web, at the time of publication it was not available in the EEA, Switzerland, the UK or Nigeria.
How do I turn it off?
In your Google Account: Data & privacy → Personalization settings → Manage Personalized Recommendations in Search Services → Connected Content Apps. You can disconnect Workspace and Google Photos there. Search Services History may remain.
Does it apply to Workspace accounts?
No. Personal Intelligence is for personal accounts; Workspace business, enterprise and education accounts are not part of this beta.
Are sensitive categories still excluded?
Yes. Race, religion, health and sexual orientation are not used for ad personalization, according to both the policy and Google's help centre.
Should I change my Google Ads strategy?
Not unless you have a separate performance signal. Monitor campaigns, but do not sell clients the myth of "email targeting".
Bottom line
The change is real but narrower than the headlines: Google expanded ad personalization to data users choose to connect through Personal Intelligence, while keeping direct advertiser access and sensitive categories off-limits. For media buyers, it is not a new targeting lever; it is another shift toward context-based personalization on Google's side. Watch performance, audit consent and do not promise clients access to data that does not exist.
