Testing your design in all the different email clients out there is the most frustrating part of sending email campaigns. Our design and spam testing tool changes all that by doing the hard work for you.
Preview in 20+ Desktop, Web & Mobile Email Clients
See screenshots of exactly how your email will look in more than 20 of the most popular desktop, web and mobile email clients like Outlook 2007, Windows Live Hotmail, Gmail, Lotus Notes, iPhone, BlackBerry and many more.
Image Blocking, Preview Window & Browser Variations
Most of the popular email clients enforce image blocking and sometimes the same email client renders your emails differently in Firefox or IE. Not only will we take screenshots of your design, but we'll take multiple versions with images on, images off and we'll even show you how it renders in both Firefox and Internet Explorer.

Spam Filter Testing & Analysis

Getting your email delivered isn't just about choosing a great email service provider. Your content might be triggering filters and not being read.
Instead of just scanning your content for "spammy words", we’ll pass your email through real spam filters and tell you which ones it passes, and which failed (though unfortunately we can't find out why).
We’ll also run your email through a number of key spam firewalls - the gatekeepers for most ISP’s and large corporations.
