OnAudience Opt Out Guide: Email, Cookies and Mobile IDs

To opt out of OnAudience, open its official opt-out page and choose the route that matches your information: email-linked data, the current browser’s cookie or a mobile advertising ID. The email route requires a confirmation link. Browser choices must be repeated across browsers and after deleting the opt-out cookie. A mobile request needs the correct AdID or IDFA.

This OnAudience opt out guide reflects the public controls checked on September 26, 2026. The current page includes an email option, so older instructions saying the service only accepts device identifiers are incomplete. We inspected the page and expanded its controls without submitting an email address, mobile ID or consumer request.

Which OnAudience opt-out should you use?

OnAudience offers audience data and advertising-related products. Its opt-out page presents three separate choices rather than one universal name-removal form. Think of those choices as different matching keys: an email address, a browser cookie and a mobile identifier each describe a different scope.

If you use several browsers and devices, more than one option may be relevant. An email confirmation does not establish that every mobile ID associated with your household was processed. Likewise, a browser cookie preference should not be interpreted as deletion of every record held under an email address.

The official opt-out page is the best starting point for these current choices. It links related privacy notices, but a privacy policy by itself is not the same thing as completing one of the actual controls.

How do you opt out of email-linked data?

Expand “Opt out of OnAudience products by email.” The page describes this route as opting out of OnAudience processing linked to the email address you enter. It presents an email field and an “Opt me out” control. Use an address you control and want the provider to match.

Enter the relevant address

Check the spelling before submitting your own request. If you have several addresses, do not assume one will automatically cover the others. Use only addresses that belong to you or for which you have authority, and ask the provider how to handle multiple identities if the situation is unclear.

Confirm through the email

The provider says it sends a confirmation message with a link that must be clicked to complete the process. A form submission alone is therefore not the final step. Check spam if the email does not arrive within the few minutes described by the page, and use the published support route if needed.

Keep the confirmation record

Save the message and the completion response you actually receive. Our research did not trigger an email, so the exact sender, link expiry and final success wording were not verified. Do not rely on a screenshot of an empty public form as proof that your own request is complete.

This email option is important because the older “Do Not Sell My Personal Info” page focuses on device-oriented matching. Where instructions differ in emphasis, use the current route that explicitly describes the data you want addressed. If necessary, ask the privacy team whether the completed email opt-out covers the particular product involved.

How do browser and mobile opt-outs work?

The browser section explains that clicking its opt-out control places an opt-out cookie in the current browser. According to OnAudience, that cookie blocks placement of its cookies. The page warns that deleting browser cookies means opting out again, and that different browsers and devices need separate action.

A browser setting is not a cross-device account setting. Work and personal browser profiles, private windows and another computer can have different storage. Check the control in the environment where you intend to retain the preference. If it does not persist, ask for assistance rather than repeatedly clearing the very cookie that records the choice.

For mobile advertising data, expand “Opt out of OnAudience Mobile ID.” The observed controls offer AdID and IDFA selections plus a required device-ID field. The page links instructions for finding the identifier on Android and iOS. Device settings and permissions can affect whether a usable identifier is available.

• Choose the route that matches the data rather than submitting random identifiers.
• For email, finish the confirmation-link step.
• For browser cookies, repeat the action in each relevant browser.
• For mobile data, pair the correct platform choice with the actual device ID.
• Keep a dated record of the confirmation or problem you encounter.

Do not use someone else’s identifier to fill a required field. If your device cannot expose an identifier, contact the privacy team and describe the limitation. Installing an unfamiliar app or weakening privacy settings just to reveal a value may not be necessary; ask what alternative evidence the provider accepts.

What if a form fails or no email arrives?

The opt-out page publishes privacy@onaudience.com for privacy and opt-out questions. It also contains a technical-error instruction referring to hello@onaudience.com.

Use the address appropriate to the problem, and explain which of the three routes failed, the date and any visible error message.

For email confirmation, check the exact address submitted and your spam folder first. Avoid repeated rapid submissions that make it harder to identify the relevant message. If you receive an unexpected request email, verify that you initiated the action before following a link.

The page includes success and error text in its underlying content. Those messages can be part of the form template even before a user submits anything. Their presence in source text is not evidence that a request was sent or completed. This guide distinguishes visible controls from actual personal submission results.

For a mobile failure, confirm the selected identifier type and avoid copying extra spaces. Ask the provider how to proceed if the identifier has changed since the activity you are concerned about. There is no basis here to promise that a newly generated ID will locate every older record.

How do you check scope and prevent lost preferences?

Save the email confirmation for email-linked processing. For a browser preference, revisit the opt-out page in the same browser and check the status it presents. For mobile data, keep the completion message tied to the ID used. These are different checks, and none should be substituted for the others.

The provider’s email instructions describe message delivery within a few minutes but do not establish a universal back-end deletion deadline. The cookie action is a preference mechanism, not proof of total historical erasure. If you want deletion or access beyond the advertised opt-out scope, ask the privacy team to clarify the applicable process.

A new email address, another device or cleared browser storage can create a different situation later. Record which environments you covered and revisit preferences when you change them. Continued advertising alone does not prove that a specific opt-out failed, since other providers and contextual ads may still be involved.

For related audience-data routes, see the Lotame opt-out guide and Eyeota opt-out guide. The data broker opt-out list, general removal guide and opt-out topic hub help organize separate requests. To investigate public people-search listings as a different task, run a free data broker scan; it does not audit OnAudience’s email, cookie or mobile-ID systems.

Frequently asked questions

Is there now an email opt-out option?

Yes. The current official page has a products-by-email section with an email field and confirmation-link instructions. That observation supersedes an assumption that only mobile or cookie identifiers can be used for every product.

Does the email route cover every device?

The page describes processing linked to the supplied email. It separately provides cookie and mobile-ID controls. Do not infer complete household or device coverage from one email confirmation.

Why must I opt out again after deleting cookies?

The browser route stores the preference in an opt-out cookie. Removing that cookie can remove the stored choice, which is why the provider tells users to repeat the action after clearing cookies.

Is a reset mobile ID enough to delete old records?

A reset changes the identifier. It does not prove that historical records tied to the old identifier were erased. Ask the provider how to address the earlier ID when that is your concern.

What if I want access rather than advertising opt-out?

Contact privacy@onaudience.com and specify the right and relevant product. The three public opt-out controls should not be treated as proof that an access request has been submitted.

Sources and verification

Official sources checked September 26, 2026: OnAudience’s opt-out page and Do Not Sell My Personal Info page. Expanded browser evidence records the current controls. No personal email, identifier, confirmation link or completed removal was tested, and no turnaround or cross-product result is promised.
