There sure are a lot of "new media" experts that don't seem to know the basics of marketing, nor "old media" communication.
You cannot deliver the most efficient marketing solution if you don't know anything about marketing.
#12 is spot on. I know some fantastic "cold sales" sales people. From life insurance to gutter-toppers, the best sales people also tend to be easily talked into buying.
This is a fantastically fun post. I don't think I am the best salesperson, but I can recall a few of these in my past.
I file every email, quickly. While I admit to having several accounts in active use, it is rare for any of them to have more than a dozen emails, even though I receive several hundred emails each day.
One thing I have learned. Have one folder to file in. Searching emails is easy, all you need is a "from" name, a date range, or a word in the subject line. The time it takes to file emails in one of dozens of organizing folders is a waste.
