Stephanie Miller from Return Path was one of five esteemed panelists at last week’s Buzz2009 webinar on the magic behind viral marketing. Her insights and expertise in e-mail marketing shone brightly in that discussion among social media mavens led by Twitter guru Guy Kawasaki. It makes sense, too, since e-mail is the original social networking tool.

There was lots of interest in the room and beyond in using e-mail to position companies well for firestorms of buzz, sales and cred.

As a follow-up, Stephanie was kind enough to offer three resources for e-mail success:

• Know if your e-mail reached the inbox.  Messages blocked by the spam filters do not earn a response. Period. Find out if your messages are reaching the inbox consistently by tracking your sender reputation.  Free snapshot at www.senderscore.org

• Calculate the cost of missing e-mail. About 20% of legitimate, permission-based marketing email never reaches the inbox.  Calculate the cost of this to your business with this free tool.
