Frequently Asked Questions

What does TowerData do?

TowerData helps you learn more about your customers so you can personalize content and generally make your customers happier. We provide demographic and lifestyle data (age, gender, marital status, income, etc., click here to see all) on U.S. consumer email addresses.


Where does TowerData get its data?

TowerData aggregates consumer data from data providers, cleanses it and maps it to emails, and ultimately makes it accessible through our easy to use Append portal and API. We partner with dozens of large and small data companies to aggregate data that we ultimately anonymize and tie to email addresses. We source it from only legitimate data bureaus who adhere to the highest consumer privacy standards -- sources that give consumers appropriate notice and choice about sharing their information and have opted in to make their data accesible.

Is my list of customers' email addresses safe?

Our data center is SAS-70 Type II certified. Please contact us if you need more details. We DO NOT contact the people you upload by any means. We DO NOT sell email addresses or other personally identifiable data you upload, or provide it to third parties. We do use the data you upload for logging, matching, linking, and inference purposes. This enables us to log our performance and improve our match rates, and also means that you'll see higher match rates down the line.

What are your match rates?

We have at least one data point on 80% of U.S. emails. To view our match rates on a data point by data point level, just type in 100 in the “number of emails” field on the pricing page. You'll see the estimated match rate percentages.

How is price calculated?

Our pricing calculator gives you a quick estimate of how much data we have on your list. We take the estimated no. of matches (i.e. our average match rates) and multiply it by the field price for each data field you selected. Every list is like a unique snowflake, so prices will vary: higher if we have more matches on your list, lower if we have less. You only pay for data we match to your list.

What’s an estimated match?

The “estimated matches” column indicates the number of matches we expect to make on your list for that given data point. We calculate this according to our average match rate % for US consumer email addresses. i.e: Gender has a 79% match rate on average. For a list of 10,000 emails, we estimate we will match 7,900 with Gender data.

What is a field price?

Each data field we have (eg. age, gender, occupation) has a price. You only pay this price when we match that data field to an email address in your list. Most are just a penny per match.

What companies do you work with?

We work with small to medium businesses, large corporations, agencies, B2B platforms and more. Our clients are generally B2C companies (or represent/work with B2C companies), who know little about their customers beyond their email address.

What about international emails?

No, we only provide information on US-based email addresses. Privacy laws vary too much from country to country, and all our data sources are US based.

What about business emails?

No, we only provide information on personal consumer email addresses. In other words, we know alex@gmail.com, not alex@towerdata.com.
