GOOD email marketing is like mastering the 15-second soundbite

Here’s a startling bit of research, done by EmailLabs and written up in MarketingSherpa, for all of you folks responsible for crafting email campaigns and newsletters:

This [past] fall tens of millions of emails from permission mailers were tested for a brand new metric: actual read time.
Turns out 15-20 seconds was the average. Consider the last email campaign or newsletter you sent. Could a typical reader skim the entire thing, digest the graphics, and decide to click on the best item for them in just 15-20 seconds?

Yes, people. You read that right. The read time of your precious prose is, on average, a lousy 15 seconds... 20 seconds, tops!

You labor so hard over that e-newsletter: spending countless hours writing it, then perfecting it, then testing it, then further refining it... and to what end? The bloody inconsiderate recipient spends a mere 15 seconds absorbing it! How rude!

So, what to do? Email marketers must become masters of the 15-second soundbite. The conventional wisdom in email marketing of short sentences, short paragraphs, placing the call-to-action so it appears above-the-fold in the preview pane, etc. etc. — just won't come close to cutting it any more.

Based on this study, I've been totally rethinking how we're doing our regular "communiques" to our clients & partners. Perhaps we should ditch our current approach of a roughly-monthly, short-and-sharp 400-word e-newsletter? I think we'll test another approach: where I strive to deliver a single idea or tip that offers real value to the recipient and coaxes that person into engaging in a dialogue with me — within a mere 80 words! (This paragraph, including this parenthetical note, is 80 words.)

Bite-sized chunks of relevant advice, personalized to that individual client's situation, sent on more regular intervals than our current "communique"... Sound like a plan? (Actually it sounds like an extranet blog, but done less frequently and delivered via email instead of RSS.)
