KnowWho Opt Out: Email Deletion and Privacy Requests

To opt out of KnowWho processing or request deletion, email privacyandsecurity@knowwho.com and specify the personal information and action involved. KnowWho's published policy expressly accepts rights requests at that address. Its linked Do Not Sell form could not open securely during our November 9, 2026 check, so this guide uses the verified email alternative.

KnowWho provides government-contact and public-affairs data services. It is not the advertising company at quorum.inc covered by our separate Quorum guide.

We inspected KnowWho's public policy and links without submitting personal information. The instructions describe available request routes, not a tested deletion result or a promise to erase official government records.

Identify the KnowWho record and your goal

A KnowWho-related concern can involve a customer account, marketing communications or professional contact information. Start with the message, notice or record that brought the company to your attention. Keep enough context to explain why you believe KnowWho holds the information, without collecting unrelated personal documents.

The policy allows requests concerning access, correction, deletion, restrictions and direct-marketing processing, subject to applicable law and exceptions. It also distinguishes ordinary promotional communications from operational messages connected with an existing relationship. Be explicit about the action you want.

Use the opt-out guide hub for other companies. Similar names are not reliable evidence of a shared controller, and a privacy request should go to the organization responsible for the particular record.

Follow the official email request route

1. Read the current served privacy page

Open KnowWho's privacy policy and find Data Subject Rights and Your Choices. The policy publishes privacyandsecurity@knowwho.com as the rights-request email. Its California section provides additional verification and authorized-agent information.

The page is served on kw1.knowwho.com and its footer identifies KnowWho.

A legacy copyright or older policy page is not proof that a request has been processed. We checked the currently served content; we cannot infer an unpublished revision date or improved workflow from its continued availability.

2. Explain the request in plain language

Send a message to the published privacy mailbox with a specific subject, such as KnowWho privacy request: deletion and marketing objection. Identify your name and relevant email address. If the concern is a professional record, add the work role or company context needed to distinguish you from someone with the same name.

A useful message asks the company to stop direct-marketing processing and to delete the specified information where applicable. Ask it to confirm which records the response covers, whether any verification is needed and whether any information must be retained. You can request correction instead if the main problem is an inaccurate role or contact detail.

The policy says California identity checks may include name and email, depending on the request and sensitivity. It does not establish one identical verification packet for every case. Do not attach a driver's license or other sensitive document simply because another provider's opt-out process asks for one.

3. Keep a record and respond to matching checks

Save the message, submission date and address used. Watch for a reply in that mailbox and check spam folders. Verify that a request for more information comes from a legitimate channel before providing it.

If the request concerns a professional listing, distinguish your private contact details from official business details. Ask what the company can suppress or correct, and what originates in a public source. A request to KnowWho does not by itself change a government office's website or public directory.

What if the linked form fails?

The policy links a Do Not Sell destination at go.knowwho.com.

Its secure URL failed with a TLS connection error during our inspection. We did not submit information through an insecure fallback, and we cannot document a working form, field labels or a receipt from that route.

The email alternative is not a guessed customer-support address: the privacy policy expressly says rights can be exercised by email. Use that route and mention the form problem if relevant. Ask the team to identify a current secure form if it prefers one.

KnowWho's policy also lists general contact details, including 1-888-566-9946 and a postal contact. Because the privacy mailbox directly addresses rights requests, it is the clearest starting point for the workflow documented here. We did not call or mail the company and do not claim those channels were operationally tested.

• Start from the official policy, not a third-party removal advertisement.
• Use the specific privacy mailbox named in the rights section.
• Keep the identity details proportional to the requested action.
• Record an acknowledgment or request reference if one is issued.
• Follow up about any unresolved scope or verification question.

Timing, retained data and reappearance

KnowWho's policy says it will respond within the period required by applicable law. It does not give one universal number of days for every region and request on the checked rights section. Ask the company to confirm the applicable response date rather than relying on an unsupported estimate from a generic guide.

The policy allows exceptions where information is needed for legal obligations or other permitted purposes. If deletion is declined or limited, ask which information remains and why. A marketing suppression action can be narrower than deleting account, transaction or service records.

Public professional data can change as a person moves roles or a government office updates its website. Ask whether a response addresses an old entry, continuing use, or both. Retain the original correspondence so a later appearance can be described with a date and source instead of starting an entirely ambiguous request.

The Pop Acta guide covers a separate political-audience workflow, and the Data Trust guide covers another political-data source. Those services need their own requests when relevant; a KnowWho confirmation does not establish their current records.

Our general data-broker removal guide explains how to organize multiple requests. For supported public exposure sources, start a CrabClear scan, while keeping KnowWho's direct response as the evidence for this specific action.

If an outdated source also appears in search results, the Google personal-information guide explains the separate search-result request and its source-page limits.

Questions about KnowWho opt-out

Is this the same company as the Quorum advertising guide?

No. The existing advertising guide expressly covers quorum.inc.

KnowWho's site identifies a public-affairs business associated with Quorum. Use the KnowWho privacy route for the records described here rather than sending the request to an unrelated advertising-data mailbox.

Can I unsubscribe instead of asking for deletion?

You can use an unsubscribe instruction to stop promotional messages, but do not assume that it also deletes every stored record. If deletion or correction is your goal, make that request separately and ask what the response covers.

Can someone make the request for me?

The California section allows an authorized agent with signed written permission and possible additional verification. Follow the provider's current process and avoid pretending to be the person concerned. Ask how to supply necessary authorization securely.

What if I no longer control the listed email address?

Explain that the record is outdated and ask for a suitable verification alternative. Do not claim access to a mailbox you no longer control. A job change may make correction and deletion questions different, so identify both the old record and the desired action clearly.

Does deletion remove official government contact information?

A response from KnowWho cannot establish a change to an independent government website or public record. Contact the original publisher about inaccurate or sensitive material there. Keep the provider request and any source correction as separate work items.

Sources and limits

Last checked November 9, 2026: KnowWho's served privacy policy, its Do Not Sell destination. The policy supports the email route, conditional verification and scope limits. The secure form failed to load, so no form screenshot or successful submission is claimed. No personal data, paid account or removal request was used in this research.
