June 30, 2010 | Posted by Carolyn Pikoulas
With 12 months of data, covering more than 500 million e-mail opens, a company called CampaignMonitor was able to analyze which e-mail clients are gaining and falling the most in popularity. Why should this matter to you?

When you send out an e-mail campaign for your business, it's important to know how your e-mail is being viewed by your recipients. Are your images being displayed correctly from mail client to mail client? How many people are reading your message on the go? By learning about your recipients, you're able to make better decisions on adjusting your message.

Below is the e-mail client market share as of January 2010. As you can see, Outlook, Hotmail and Yahoo! currently hold most of the market, while iPhone usage is growing at a rapid pace.

With our e-mail service, you can see exactly how your e-mail looks in any e-mail client with a click of a button. From there, you can tell if anything in your e-mail needs changed. In addition, we can pass your email through real spam filters and tell you whether or not your message will fail.
