How long should your email newsletter article copy be if you are trying to get readers to click to your site for the whole thing? The answer is: probably longer than you think.
I used to think I could just send out an enticing headline and folks would click. Then I tested the same headline plus one terse line of explanation. Then a reader emailed me saying, "Anne could you give me more details so I know if a particular story is worth my clicking to?" So I started to write longer and longer. Now some summaries in our weekly summaries letter (SherpaWeekly) are up to three short paragraphs long.
The other thing I learned over time is NOT to do the old first-hundred-words-of-the-article routine with an elipsis (...) as the summary. Yes, it's easier than writing an all-new summary, but it's not nearly as effective. You need to tell you reader exactly what they'll get when they click through, and why it's important to them.

This Case Study is a must-read for all business-to-consumer marketers trying to build an opt-in email database. Interactive ad agency execs, who are trying to convince clients to invest online, will also thoroughly appreciate how an online campaign, that was a "little add-on" to a big traditional media buy, ended up making a giant impact on the client-side.
Our favorite bit is when the agency involved predicted how successful the campaign would be. They were waaay offhttp://www.marketingsherpa.com/sample.cfm?contentID=1965
