Performance statistics - compendiums
The 2012 Email Marketing Benchmark Guide is the latest iteration of Sherpa's annual stat fest for email marketers, with 194 pages and over 170 charts and tables. This one includes data from a survey of 2700+ marketers.
The Email Marketing Factbook is a 67 page, 39 chart report which includes data on consumer behavior, response rates, current practices and tactics, etc.
Collates individual statistics across 30+ relevant categories. Also runs its own occasional surveys, for example on compensation in the email marketing industry. Unlike all of the above, it's free.
Produces two reports with statistics of interest to email marketers:
- The Email Marketing Census 2012 is an 83-page look at UK marketer attitudes, opinions and practices regarding email marketing issues, interspersed with commentary from experts.

Performance statistics - North America and International
You'll need to browse through their press releases to find links to quarterly "Email Trends and Benchmarks" reports on open rates, click rates and inbox deliverability, often broken down by industry. These are calculated based on the emails sent out by this ESP's customers

Email client popularity, based on data collected from this email service provider's user base.
Notes: Email client tracking is only possible for those clients and webmail services that record an open (i.e. download a tracking image). Given the prevalence of image blocking, this can lead to skewed results. Be sure to read the caveats offered by the reporting services above.
