As digital marketing shifts toward privacy-first solutions and third-party cookies fade away, hashed emails have become one of the most powerful identity tools available today. They allow marketers to recognize users across devices and platforms—without revealing the actual email address.
What Is a Hashed Email?
A hashed email is a user’s email address that’s been encrypted using algorithms like SHA-256 or MD5.
This HEM or Hashed Emails can be used to:
1. Recognize users across different devices
2. Match customer profiles in a secure way
3. Enrich leads without accessing raw email addresses
Why Hashed Emails Matter More Than Ever
With the loss of third-party cookies, advertisers need reliable, permission-based identity signals. Hashed emails solve this by providing:
• High match rates across platforms like Meta, Google, LinkedIn
• Persistent identity across mobile, desktop, apps, and CTV
• Better attribution and audience building
1. Identity Resolution & Customer Matching
How Marketers Use It
1. A user enters their email on a website or form.
2. The email is normalized and hashed.
3. The hashed email is sent to an identity provider like DataZapp via bulk upload or API.
4. DataZapp’s identity graph matches the hash to a known consumer or business profile.
Why It’s Important
• Connects mobile → desktop → CTV → apps into one profile
• Links online activity with offline details
• Works even when cookies are gone
• Enables retargeting and lookalike audiences
2. Real-Time Data Enrichment Using Hashed Emails
Marketers use hashed emails to instantly enrich a user with powerful data signals. DataZapp can match a hashed email to:
• Age, gender, household income
• Homeowner & property data

• Political voter & donor information
• Consumer lifestyle interests
• Updated email & phone numbers

DataZapp delivers this in real time, often within seconds—while competitors require days and charge 5–10× more.
