Fingerprint, from Litmus

Email client usage statistics
for your mailing list.

There has been no way to get accurate, up-to-date statistics on email client usage. Until now.

Fingerprint shows you which email clients your readers are using.

Knowing which email clients are popular means you can be certain your messages are being displayed as you intended. Get actionable statistics within 24 hours of sending your next campaign.

How does it work?

You'll be given a single line of HTML code to add to your email newsletter template. The next time you send out a campaign, Fingerprint's patent pending technology will deliver near-realtime statistics, showing you exactly which email clients your customers are using.

What can Fingerprint tell you?

Fingerprint can tell you things it was previously impossible to know. It can answer questions such as...

  • Which email clients should I be testing our campaigns with?
  • How many people read our emails on their BlackBerry or iPhone?
  • How many of our readers have upgraded to Outlook 2007?
  • How many people really use Lotus Notes?
  • Which web browsers do our readers use when they read our emails online?
  • Are our webmail subscribers reading our emails online, or in software clients on the desktop?
