How to Opt Out of TowerData (AtData)

TowerData, now operating under the name AtData, is a data broker that specializes in email intelligence. The company collects personal information — including your name, email address, postal address, age, gender, and more — from surveys, online forms, cookies, and partnerships with other data providers. This data is then sold to marketers who use it for targeted advertising campaigns. Here's how to remove your information from their database.

What Is TowerData (AtData)?

AtData (formerly TowerData, and before that, Instant Data) is an email-centric data services company. Their core product takes an email address and enriches it with demographic and behavioral data — giving marketers detailed profiles they can use for targeted ads and outreach.

The types of data TowerData/AtData may have about you include:

  • Full name
  • Email addresses
  • Current and past postal addresses
  • Phone numbers
  • Age and date of birth
  • Gender
  • Names of family members
  • Social media profiles
  • Consumer interests and purchasing behavior

They collect this information from opt-in subscriptions, public information sources, online forms you may have filled out, and partnerships with other data providers.

Use a Disposable Email

When contacting any data broker to opt out, always use a disposable email address — not your primary one. Data brokers have been known to add your contact information to new marketing databases when you reach out, even if the purpose is to request removal.

How to Opt Out of TowerData/AtData

Method 1: Use the Official Opt-Out Form

AtData provides a direct opt-out page. Follow these steps:

  1. Navigate to https://instantdata.atdata.com/optout
  2. Enter your email address in the form
  3. Fill in your full name
  4. Enter your complete postal address
  5. Complete the CAPTCHA verification
  6. Click Submit

After submitting, AtData should confirm the removal of your email and postal address from their records. The process is typically immediate, but allow up to 30 days for complete removal from all systems and partner databases.

Method 2: Use the "Do Not Sell" Link

You can also opt out through TowerData's main website:

  1. Go to towerdata.com
  2. Scroll to the bottom of the page
  3. Click "Do Not Sell My Personal Information" in the footer
  4. You'll be redirected to a removal form
  5. Fill in your personal details and submit

Method 3: Email Request (CCPA/State Law)

If you're a resident of California, Minnesota, Colorado, Virginia, Connecticut, or another state with a consumer data privacy law, you can send a direct email citing your legal right to deletion:

  1. Send an email to AtData's privacy contact address (found in their privacy policy)
  2. Include your full name, email address, and postal address
  3. Cite your state's privacy law (e.g., CCPA, MCDPA, CPA) and request deletion of all personal data
  4. Request confirmation of deletion within 45 days

California Residents

California's DELETE Request and Opt-out Platform (DROP) lets you submit a single deletion request to 500+ registered data brokers. Starting August 1, 2026, brokers must delete your data within 90 days. Visit privacy.ca.gov/drop to use this free tool.

Verify Your Removal

After submitting your opt-out request, take these steps to confirm your data has been removed:

  1. Wait 30 days for the removal to propagate through all systems
  2. Check back by visiting the AtData opt-out page and searching for your information
  3. Document everything — save screenshots of your opt-out submission and any confirmation messages you receive

Why Your Data May Reappear

Even after a successful opt-out, your information can reappear in TowerData's database. Here's why:

  • Data partner re-imports — AtData sources data from multiple partners. If a partner still has your information, it can be re-imported during routine database updates.
  • New data collection — if you fill out a new online form, survey, or contest entry that feeds into AtData's data pipeline, your information enters their system again
  • Public records — changes like moving to a new address, registering to vote, or purchasing property generate new public records that data brokers can scrape

This is why one-time opt-outs aren't enough. You need ongoing monitoring to ensure your data stays removed.

The Automated Solution

Manually opting out of TowerData is just one site among the 200+ data brokers that likely have your information. The average person's data appears on over 200 data broker websites, and each one has its own opt-out process.

PrivacyOn simplifies this by handling the entire process:

  • Scans 100+ data broker sites for your personal information, including email intelligence brokers like TowerData
  • Submits opt-out requests automatically on your behalf
  • Monitors 24/7 and re-submits removal requests when your data reappears
  • Dark web monitoring alerts you when your email, passwords, or other data surfaces in breaches
  • Family plans protect up to 5 household members starting at $8.33/month

Other Email Data Brokers to Opt Out Of

TowerData/AtData isn't the only email intelligence broker. Consider also opting out of:

  • Acxiom — one of the largest data brokers; opt out at their consumer choices page
  • Epsilon — a major marketing data broker; opt out through their consumer preference page
  • Oracle Data Cloud (formerly BlueKai) — opt out through Oracle's data cloud privacy page
  • LexisNexis — opt out through their consumer disclosure page

Each of these brokers has its own opt-out process, or you can use PrivacyOn to handle all of them automatically.

Protect Your Email Address Going Forward

To minimize future data collection, adopt these habits:

  • Use email aliases — services like Apple's Hide My Email, Firefox Relay, or SimpleLogin let you create unique addresses for each service you sign up for
  • Avoid using your primary email for contests, surveys, or free trials — these are prime data collection points for brokers
  • Read privacy policies before submitting your email — look for language about sharing data with "partners" or "affiliates"
  • Use a dedicated "junk" email for any situation where you suspect your address might be sold

Take Control of Your Data

TowerData/AtData profits from collecting and selling your personal information to marketers. You have the right to opt out and demand deletion of your data. Whether you handle the process manually or use PrivacyOn to automate it, taking action ensures your email address and personal details aren't being traded without your consent.
