Can Google Use Your Gmail to Show You Ads Now? What Changed on October 16 and Who It Affects

Yes, since October 16, 2026 it can, with one condition: you have to connect Gmail or Google Photos to another Google service that shows personalized ads, such as Personal Intelligence in Google Search. The new privacy policy says Google does not show ads based on your content from Drive, Gmail and Photos "unless you choose to make data from these services available" to a service that supports personalized ads. The feature is open to personal accounts only, and paid Google Workspace accounts are excluded. If your company's correspondence runs through free gmail.com accounts, check the three settings below today, and seriously consider moving work email to an account on your company's own domain.

What exactly changed in Google's privacy policy?

Since July 1, 2021 the privacy policy said, with no exception: "We don't show you personalized ads based on your content from Drive, Gmail, or Photos." The version in force from October 16, 2026 adds an exception to that same sentence: unless you choose to make data from these services available to other Google services that support personalized ads. The policy also adds an explicit example: Search may process some of the data you allow it to access to personalize content, "including ads."

Put simply: your inbox stays out of advertising as long as it stands alone. Once you connect it to Google Search, what Search infers from your email becomes material that can shape the ads you see. The change went in quietly, and few people noticed until tech sites reported it about a week later.

What is Personal Intelligence, and who can turn it on?

Google launched the feature in AI Mode in Search on January 22, 2026 for Google AI Pro and Ultra subscribers in the US, in English. Today the official help page says it is available in more than 190 countries and territories and in more than 80 languages, and it requires:

• That you are 18 or older.
• That the account is personal; work, enterprise and education accounts are excluded.
• That you turn on "Personalized Recommendations" in your Google Account, then choose to connect the apps yourself.

The apps that can be connected today are Gmail, Google Calendar (US and English only) and Google Photos (not available in every region). Connecting is opt-in, and Google says it does not train its models directly on your inbox.

Can advertisers see my emails?

No. The help page says advertisers have no access to connected content, and that ads "will not be based directly" on your inbox or your photo library. An older rule still holds: no personalized ads based on sensitive categories such as race, religion or health. But the important word is "directly." Search draws summaries and inferences from your email, and those inferences are what may shape the ads. If your inbox holds quotations, contracts and supplier correspondence, you are letting Google draw meaning from them even though nobody reads the message itself.

Why does this matter to a business owner in particular?

Many small businesses in Saudi Arabia start with a free gmail.com account for the owner or for sales, and the account grows until it carries customer invoices, contact details and price quotes. In Google's eyes that account is "personal," so the new exception applies to it if someone on your team turns the connection on. For paid Google Workspace accounts, Google states in its privacy commitments for Workspace and Google Cloud: "We never use your data for ads targeting," and it does not process customer data to build ads profiles. The difference, then, is not the service itself but the type of account you run your business from.

There is your customers' side too: work email holds their names, numbers and the details of their dealings with you, and connecting it to an advertising service is a decision the business should make deliberately, not one an employee makes while trying a new feature on their phone. If you want to review your business's obligations toward customer data, start with our practical guide to the Personal Data Protection Law.

3 steps to take today

1. Check the connection: in your Google Account open Search Services Personalization, then Additional Personal Intelligence, then Connected Content Apps, and disconnect Gmail and Google Photos if they are connected on an account that holds work data. In Gmail settings, review "Smart features in other Google products."
2. Delete the old history: disconnecting an app does not delete what was already saved in Search Services History. Go to myactivity.google.com and delete the activity if you want it gone, and review your ad settings in My Ad Center.
3. Separate work from personal: move company email to accounts on your own domain in Google Workspace or Microsoft 365, and write a short policy that bars connecting work accounts to any AI feature without the administrator's approval.

So should I leave Gmail?

No need to panic. The change does not switch itself on, and it does not touch your account unless someone turns the connection on. But it is a reminder of a simple rule: free services are funded by advertising, and every new AI feature needs your data to work, so read what you are agreeing to before you tap "Connect." We covered the same idea for connected apps in Who Can Get Into Your Company's Microsoft 365 Without a Password?

The Origami view

We see a lesson in this change that is bigger than Gmail: the line between business data and personal use has to be drawn in the settings and in company policy, not left to each employee's taste. When we build systems for clients that connect to email or to AI models, we decide from the start which data leaves, where it goes and with what permission. If you want your company's accounts and connected tools reviewed, or your work email moved into a properly controlled business environment, get in touch.
