I am getting a ton of great feedback on the Tip Of The Day email series. People reply to the emails daily with questions. Some people want more information, some people want less. Some people don't want to click through to a longer article.
So here is what I am thinking:
1. Make sure there is a nice "nugget" in the body of the email
2. Put links to the full article in case people do want to read more
These are small adjustments and I will continually incorporate the feedback. The most important thing though is please keep asking questions. Reply to the emails.
