Traditional e-mail is about static content. It’s time to get active with scrolling strips, creative animations, count-down timers, and other widgets that grab attention, engage users and drive them to look again — and click!

  • Real-time content with update-on-open
  • Personalized for relevance
  • Templated for easy implementation
  • Device-aware for mobile presentation
  • Ready to roll — no download required

Let PowerInbox help you serve the right message to the right individual on the right device.


Website functionality inside an email.

No matter the call to action, a click in traditional email means opening up a browser and shifting away from the “flow” of reading your mail. Finally, with a quick browser extension, you can offer a complete, interactive experience for immediate gratification and a spike in engagement.

  • Time-saving as readers interact on the spot
  • Do it all: browse, read, respond… purchase!
  • Personalized for relevance based on previous activity saved in browser cookies
  • Templated for easy implementation in your EMS
  • Widgets galore: menus, video, forms, content navigation… anything you do on a web page.
