How to Opt Out of Bombora

Bombora is the company that invented the B2B intent data category. Through a cooperative network of over 5,000 B2B publishers, Bombora tracks which topics businesses are actively researching and sells those signals to sales and marketing platforms. If a vendor has ever contacted you at exactly the moment your team was evaluating their product category, Bombora's data likely played a role. Here is how to opt out — and what opting out actually means for a platform that operates very differently from traditional data brokers.

What Is Bombora and How Does It Work?

Bombora, headquartered in New York City, operates a unique data cooperative model. Rather than scraping the web or buying data from third parties, Bombora partners with a network of B2B media publishers — industry blogs, trade publications, research sites, and content platforms. These publishers share anonymized content consumption data with Bombora in exchange for aggregated market insights.

Here is what makes Bombora different from most data brokers:

• Company-level data, not individual-level: Bombora claims it never tracks or stores personal information at the individual level. Instead, it groups browsing behavior by company. The output is a signal like "Company X is showing elevated interest in cybersecurity solutions" rather than "John Smith at Company X read three articles about firewalls."
• Cooperative data model: The publishers in Bombora's co-op are the ones collecting the raw data. They are responsible for obtaining user consent and providing opt-out mechanisms on their own sites.
• Topic surge signals: Bombora measures when a company's research activity on a specific topic exceeds its historical baseline. These "surge" signals are what get sold to platforms like 6sense, Demandbase, and dozens of other B2B marketing tools.

The types of data flowing through Bombora's system include:

• Company-level intent signals: Which topics a business is researching, how intensely, and for how long
• IP-based company identification: Mapping IP addresses to company names to attribute browsing activity
• Cookie and device identifiers: Used to connect browsing sessions across publisher sites within the co-op network
• Content consumption patterns: Which articles, whitepapers, and resources are being consumed, aggregated by company

What Does Opting Out of Bombora Actually Do?

Here is what opting out does and does not accomplish:

What It Does

• Drops an opt-out cookie that tells Bombora's tracking scripts to exclude your browsing data from their co-op aggregation
• Removes your device from contributing to your company's intent signals
• Complies with your preference not to have your browsing behavior tracked across Bombora's publisher network

What It Does Not Do

• Remove a personal profile: Unlike ZoomInfo or Apollo.io, there is no individual dossier with your name, email, and phone number to delete. Bombora's data model does not work that way.
• Stop your company from being tracked: Other employees at your company will continue to generate intent signals. Your individual opt-out only removes your device's contribution to the aggregate.
• Affect data already delivered: Intent signals that have already been sent to Bombora's customers (6sense, Demandbase, etc.) cannot be recalled.
• Persist across browser changes: Since the opt-out is cookie-based, clearing your cookies, switching browsers, or using a new device will require you to opt out again.

How to Opt Out of Bombora: Step-by-Step

Bombora offers several ways to opt out of their data collection:

Method 1: Online Opt-Out

1. Visit bombora.com:

   Navigate to bombora.com and scroll to the footer of the page. Look for links labeled Privacy Policy, Do Not Sell My Info, or Your Privacy Choices.

2. Navigate to the privacy or opt-out page:

   Click through to Bombora's privacy page where opt-out options are listed. Follow the instructions to submit a cookie-based opt-out or a formal privacy request.

3. Complete any required forms:

   Provide your name and email address if prompted. Bombora may ask for the basis of your request (CCPA, GDPR, or general preference).

4. Confirm via email if required:

   Check your inbox for a verification email and click the confirmation link to finalize your request.

Method 2: Email Request

For a more direct approach, send an email to:

• Email: privacy@bombora.com

In your email, include:

• Your full name
• Your email address
• A clear statement that you want to opt out of Bombora's data collection and processing
• The legal basis for your request (CCPA right to opt out, GDPR right to object, or general privacy preference)

Method 3: Opt Out Through Individual Publishers

Because Bombora's co-op model places data collection responsibility on the publishers themselves, you can also opt out at the source. When you visit B2B media sites and industry publications, look for:

• Cookie consent banners — decline or customize tracking preferences
• Privacy settings pages — disable third-party data sharing
• "Do Not Sell" links in footers — submit individual opt-out requests

This approach is more labor-intensive but can be effective because it prevents data from entering Bombora's pipeline in the first place.

Keeping Your Opt-Out Active

To maintain your opt-out over time:

• Be selective about clearing cookies — use browser tools that let you preserve specific opt-out cookies while clearing others
• Install a privacy browser extension that blocks third-party tracking scripts, including Bombora's, before they execute
• Use a VPN or IP masking tool to prevent IP-based company identification, which operates independently of cookies
• Periodically revisit your opt-out — set a reminder every few months to verify that your opt-out is still active

Bombora in the Broader B2B Data Ecosystem

Bombora does not operate in isolation. Its intent data feeds directly into major B2B platforms including Demandbase, 6sense, Madison Logic, TechTarget, and many CRM and marketing automation systems. Even if you opt out of Bombora, these downstream platforms may still have your data from other sources. To meaningfully reduce your B2B data exposure, you need to opt out across the entire chain:

• Demandbase: ABM platform that uses Bombora intent signals combined with its own data
• 6sense: AI-powered ABM platform with its own intent data collection
• ZoomInfo: The largest B2B contact database with individual-level profiles
• Apollo.io: Sales engagement platform with 275M+ contacts
• Clearbit: Data enrichment platform now owned by HubSpot

Automate It with PrivacyOn

Managing cookie-based opt-outs, emailing privacy teams, re-submitting requests after browser resets, and tracking which platforms feed data to which other platforms is an ongoing burden. PrivacyOn automates opt-out requests across 100+ data brokers, including B2B intent data platforms like Bombora and the downstream services that consume their data. PrivacyOn continuously monitors for data reappearance and re-submits removal requests when needed, so a single enrollment provides persistent protection without the manual upkeep.
