Increase in eMail opens with longer subject lines...

You will get see an increase in Email opens with longer subject lines. Remember, your subject line needs to open the dialogue and encourage further interaction. Because you have a matter of microseconds to garner enough interest for an open, relevance trumps brevity, no matter what the subject line gurus tell you each day. Though they should be as brief as possible, do not sacrifice relevance to your audience, just to save a few characters.
