Key Points

  • Why did we make it? Playwire’s new Hashed Email API is an innovative solution to the problem of audience identification that has emerged as a result of the impending elimination of third-party cookies.
  • What is it? The solution encrypts individual email addresses into a secure 32-digit code that enables publishers to identify and track users across platforms and channels.
  • What makes it unique? In addition to all the good stuff hashed email provides, Playwire sweetens the deal with simple, user-friendly code, seamless integration with our DMP, and direct connections to identity providers like LiveRamp and The Trade Desk.
  • How do you get it? You can access the publisher-facing version by implementing a single line of code on your website or app.

Great news: we’re doing it again. 

(It = blowing your mind with a kick-ass new feature.)

In the haze of chaos that ensued since Google announced the end of third-party cookies, one solution has emerged triumphant: Hashed Email.

Never heard of her? Allow us to introduce you.

Hashed email is a process that transforms an online visitor’s email into an unrecognizable code of letters and numbers.

For publishers, the emergence of hashed email is huge. It presents an opportunity to track users across browsers and devices in a secure way, protecting your users’ personal data and shielding your site from legal risk.

It’s easy to see why there’s a ton of excitement about it in the ad tech industry, and why our team had to get on board ASAP.

But, as usual, Playwire wasn’t content to create just another standard hashed email solution for our publishers. You know we had to add our special sauce.

So what is our new Hashed Email API? And what makes it stand out from the crowd?

Keep reading and we’ll tell you.

What Makes Playwire’s Hashed Email API Solution Unique?

Our new Hashed Email API has all the benefits and functionalities you can expect from a quality hashed email solution, and then some.

Of course, there’s —

  • Multiple device tracking
  • Multiple browser tracking
  • Increased reliability
  • Better audience segmentation
  • Privacy law compliance

All of this makes hashed email preferable to cookies. And it’s pretty standard for most email hashing solutions.

But here’s how we take it even further —

  • Simple, elegant code: Our line of code is easy to implement. With a single line, our publishers can identify users across multiple sites and channels, unlocking critical data.
  • Direct integration with our DMP: With a straight line from the Playwire Hashed Email API to our proprietary data management platform, you can access highly sophisticated segmentation tools that help you deliver more value to your audience and premium advertisers looking to buy inventory across your site.

  • Collaboration with major identity providers: You can’t maximize your revenue without unlocking the full spend from advertisers. And our solution does that by working with the largest identity providers — like LiveRamp and The Trade Desk — who your buyers already rely on to target your users. 

Surely we don’t need to spell it out for you, but we love to brag. So we will.

The benefits you get from using our Hashed Email API equal —

  • Improved user experience
  • Better engagement
  • Increased CPMs
  • Higher valued inventory and fill rates

(AKA: more $$$ for you)

How Publishers Can Access Playwire’s Hashed Email API


We thought you might be.

Luckily, we made the implementation simple. All you need to do is add the line of code to your site pages, appended to the ad tag code we will have you place on your site during the onboarding process with us.

Additionally, once you’re using Playwire’s Data Layer, you can use the same object with the Hashed Email API as well.

Because why overcomplicate things?

Once you’ve implemented the code on your site, you can enable integrations with identity partners like LiveRamp in the RAMP Platform

Then, the fun begins.

Doesn’t seem simple to you? No worries. Our support team is here to help you with whatever is on your mind.
