Google changed its Gmail ads promise. Here is the wording, old and new.

Picture the welcome email your salon sends a new client. It thanks her by name, confirms her first appointment, mentions the color service she booked and offers a discount on her next visit. It sits in her Gmail. For almost a decade, Google's public answer to "does that email shape the ads she sees?" was a flat no.

On October 16, 2026, Google added a narrower answer. It applies only to people who choose to connect Gmail to Google's search services, and it is worth reading word for word, because a lot of what is being said about it online goes further than the text does. In Part 1 we looked at Amazon removing product names from its order emails. This part is about the inbox those emails land in.

The 2017 promise

On June 23, 2017, Diane Greene, then CEO of Google Cloud, announced that consumer Gmail would line up with the business version, G Suite, on ads. The sentence people remember is this one:

"Consumer Gmail content will not be used or scanned for any ads personalization after this change."

That pledge is why "Google reads your email to target ads" has been wrong as a blanket statement since 2017, and it still is.

What Google added on October 16, 2026

Google did not take the 2017 post down. It added an update at the top of the same page, dated October 16, 2026:

"As we've continued to make Google products more personalized and helpful, we've added features that enable users to choose to connect apps like Workspace apps to other Google services. If users choose to enable these new features, data from Workspace Apps will be processed to personalize other Google experiences, and depending on a user's settings, that same subset of data can also be used to show ads."

The update links to a Google Search help page about connecting what Google calls content apps (today Gmail and Google Calendar, plus Google Photos) to Search services such as AI Mode, Maps and Shopping. Its answer to the question "will my Gmail inbox or Google Photos library be used to serve ads?" reads, in full:

"Ads will not be based directly on your Gmail inbox or your Google Photos library. If you connect your content apps to Search Services, Search may reference summaries, excerpts and inferences from these sources to personalize your experience and do things for you. That same info may be used to show you ads, so they are even more helpful for you."

Opt-in, and what that limits

The new rule applies to people who opt in. The help page is direct about it: "You get to choose if you want to connect your content apps to Search Services." It adds that you can still use AI Mode without connecting anything, and that "You can adjust your settings, including disconnecting content apps from Search services, at any time."

The same page sets other limits. Connecting is open to users 18 and older who are signed in to a personal Google account, in supported countries. Google says "advertisers will not have access to your Gmail inbox or Google Photos," and that it "doesn't show you personalized ads based on sensitive categories, such as race, religion, sexual orientation, or health."

2. 2The referenceSearch "may reference summaries, excerpts and inferences" from the inbox
3. 3The answerAI Mode and other Search services personalize what they show
4. 4The ad"That same info may be used to show you ads"

So what does this mean for a business that sends email? A few things, said carefully.

First, most of your customers have not connected anything, and the old pledge still describes their inbox. We do not know how many people have opted in, and Google has not said.

Second, for the ones who have, Google's wording allows an inference drawn from their mail to inform the ads they see in Search services. PPC Land reported that Google confirmed around October 16 that it had started testing ads in AI Mode for people who connect apps this way. We found no named Google spokesperson quote on that test, so treat it as reported.

Third, nothing in the text says your email, specifically, will be used to show your customer a competitor's ad. Google has not published how any one email feeds an inference, and we will not guess. The wording does mean that, for a connected user, what sits in the inbox may now inform the ads they see. You can plan around that much.

Where your best offers should live

None of this is a reason to stop sending email. Email is still the cheapest way most studios, spas and gyms reach a customer who already said yes. The lesson is about where the offer lives. If your best deal exists only as a line in an email, it lives in a building someone else runs, under rules that changed this month and can change again.

1. Give every offer a home page

   Each promotion gets its own page on your website with the price, what is included, the end date and the locations. The email links to it.

2. Put members' perks behind your own login

   Renewal pricing, referral credits and class-pack balances belong in your app or member portal, where the customer sees them on your terms.

3. Use SMS for the time-sensitive ones

   A same-week opening or a last-chance renewal can go by text to people who opted in, pointing to the same page.

4. Write emails that work as pointers

   Assume a summary may reach your customer before your words do. Lead with the offer and the link, so the summary still sends them home.

Say a five-location med spa runs a spring package. If the details live on a page it owns, that page works the same whether the customer read the email, saw a summary of it or never opened it. If the details live only in the email, the inbox decides how much of it she sees.

Next, in Part 3, we look at the other rules Google sets for the inbox: who may send, how the Promotions tab ranks mail, and the ad slot at the top of it. For how AI summaries change what your customer sees first, read Your email gets read by an agent first.
