About this report
This report shows the current state of the email client market. It serves as the largest ever study of its kind, with data from almost three million email recipients. To run an analysis like this on your own mailing list, look at the Fingerprint service.

Consumer Data collected from 1,963,046 email recipients using the Fingerprint analysis tool. The mailing list owners classified their mailing list as mainly consumer users. This chart shows the top 10 email clients by market share. Compiled 11 September 2008 (revised 15 September 2008).

Caveats
Email clients are recorded when images are loaded within an email. Some email clients block external images, or are not capable of displaying HTML email. That includes non-current models of Blackberry, and other mobile devices unable to view HTML email. As a result these are not tracked and do not appear in the report.
 
Further to that, the report only shows the top 10 email clients we have detected. In total Litmus can detect over 3,000 different clients. Because of this diversity Litmus recommends analysing your own mailing lists to gain the most accurate information, since results can vary greatly depending on your lists' demographics.
