The email marketing world has many great minds and as a result excellent blogs, websites and newsletters. Below are some of my most frequented web based stops as I look to my peers for learnings, case studies and ideas.
2 places that provide a great starting point are both from EmailMarketingReports.com, the preferred home page for many in the email marketing industry (it should be noted that the site's publisher was a contributor in The Truth About Email Marketing). The site has noted some of the best thought leaders, newsletters and blogs which make it easier for you to decide where to dive in.
Now on to some of my recommendations:
Websites
