Testing your design in all the different email clients out there has got to be the most frustrating and time consuming part of sending email campaigns. Our design and spam testing tool changes all that by doing the hard work for you. For a small fee you'll get all this with a single click...
Screenshots in all the major email clients
See screenshots of exactly how your email will look in more than 15 of the most popular email clients like Outlook 2007, Windows Live Hotmail, Yahoo, Gmail, Lotus Notes and many more.

Image blocking and preview pane ready
Most of the popular email clients enforce image blocking and preview panes these days. Not only will we take screenshots of your design, but we'll take multiple versions with images on, images off and even how your design looks in the horizontal or vertical preview pane.

Your email tested against spam filters and firewalls
Instead of just scanning your content for "spammy words", we’ll pass your email through real spam filters and tell you exactly why you failed. We’ll also run your email through a number of key spam firewalls - the gatekeepers for most ISP’s and large corporations.

But can't I just do this myself for free?
Sure, but it sucks. You'll need to create test accounts at all the free ISP's above like Hotmail and Yahoo, sign up (and pay) for other ISP's like Earthlink and Comcast, set up a few virtual machines to cover different operating systems and purchase and install each of the spam filters we test in. Total cost, just under $10,000.
Or, you can click your mouse once and we'll do the lot for you.
Do I have to be a customer to use it?
Nope. As long as you have a free account with us, you can use our testing tool to get your design just right with no obligation to use Campaign Monitor for anything else.
