While doing a little research on email marketing, I came across this nifty site called EmailStatCenter.com.  Since I found it to be helpful, I wanted to pass it along to you guys.  This site is the first centralized online repository of statistics and research specific to the email marketing industry, with a broad range of topics included. 

EmailStatCenter.com provides statistical information for those looking for quick facts, but also provides the name of the reports if you’d like to research further.  Let’s face it, if you’re trying to convince people there’s value to an email marketing program, stats will be extremely helpful in your argument.

Here are some facts that I found particularly interesting:

• Of the largest online retailers that send welcome emails, 69% of them send their welcome emails in HTML, while the remaining 31% sent theirs in text-only format. - Email Experience Council/RetailEmail.Blogspot (September 2006)
• 55.3% of marketers surveyed currently use, or plan on using an outside vendor for email marketing. - Datran Media Research, “The 2007 Email Marketing Survey: Looking Forward” (2007)
