If you're running programmatic ads in your emails through Kit Ads, you'll need to include a subscriber opt-out link for preference-based ads in every email that contains programmatic ads. We also strongly recommend updating your privacy policy to mention preference-based advertising.

These steps protect your subscribers' privacy and help keep you in compliance with applicable data privacy regulations.

Every email that contains programmatic ads must include an opt-out link so subscribers can opt out of preference-based, personalized ads.

This opt-out link doesn't remove ads from your emails entirely. Subscribers who opt out will simply receive non-personalized ads instead of ads targeted to their preferences.

We also strongly recommend adding language about preference-based advertising to your privacy policy.

Including an opt-out link for preference-based ads is a legal compliance requirement that protects consumer privacy. It also signals transparency and helps build trust with your audience.

Without this link, you risk serving personalized ads to subscribers without giving them a way to opt out — which could put you in violation of applicable data privacy regulations.

Open the email template(s) you use to run Kit Ads. You'll need to add the opt-out link to every email template that contains an Ad Slot.
​

In the footer area of your email, add the following snippet:

{{ck.privacy_notice}}

This snippet automatically generates a link in your sent emails, directing subscribers to a simple form where they can manage their ad preferences.

Make sure you add this snippet to every email template that includes an Ad Slot — including any Broadcast and Sequence emails that run programmatic ads.

We strongly recommend reviewing your website's privacy policy to make sure it covers preference-based advertising. Clear language about this practice matters for both compliance and transparency.

Here's an example of language you could include. We recommend consulting a legal professional to confirm it's appropriate for your specific situation.

Interest-Based Advertising

We work with third parties to serve advertisements and perform related services across the web and in mobile applications. You can learn more about interest-based ads, or opt out of having your web browsing information used for behavioral advertising purposes by companies that participate in the Digital Advertising Alliance, by visiting www.aboutads.info/choices.

Opting Out of Targeted Advertising, Sharing, and Sales

We process personal information to understand and improve your experience with our Services and to serve you relevant advertisements. Some of these activities may be considered "sales" or "sharing" of your personal information or "targeted advertising" under certain privacy laws. To opt out of preference-based advertising, use the form linked below. Note that opting out won't stop ads from appearing in your emails entirely — those ads will just be selected randomly rather than based on your preferences.

If your emails contain programmatic ads but don't include the required opt-out link by the compliance deadline, programmatic ads will be automatically removed from those emails. Your emails will still send as normal — they just won't include programmatic ads until you're back in compliance.

That means you'll miss out on ad revenue until the opt-out link is added.

To resume earning programmatic ad revenue, add the {{ck.privacy_notice}} snippet to your email templates and your ads will start running again.

Do I need to manually add the opt-out link, or will it be automatically included?

You'll need to manually add the {{ck.privacy_notice}} snippet to your email templates. It won't be added automatically.

Will my emails be blocked from sending if I don't include the opt-out link?

No — your emails will still send as normal. After the compliance deadline, however, programmatic ads will be automatically removed from emails that don't include the opt-out link, and you won't earn ad revenue from those emails.

What about emails I've already scheduled?

If you have scheduled emails that contain Ad Slots, you'll need to update them to include the opt-out link. If you have a large number of emails that need updating, email help@kit.com and we'll help you out.

What happens to subscribers who opt out of preference-based ads?

They'll still see ads in your emails, but those ads will be randomly selected (within your brand preferences) rather than personalized to their interests. They may also see fewer ads overall, since our system can no longer match them with the most relevant options.

My privacy policy already mentions interest-based advertising. Do I still need to update it?

If your privacy policy already covers preference-based advertising, you may be good to go. That said, we recommend checking with a legal professional to confirm your language covers your specific situation.

What legal consequences could I face if I don't comply?

Without the opt-out link, you risk serving personalized ads to subscribers without giving them the ability to opt out, which could put you in violation of applicable data privacy regulations. Adding the link protects both you and your audience.
