I'm glossing over email lists quite a bit, but because it's such an important tool for outreach (not to mention one of the things you own online), make sure you have an email signup integrated.
Chris Lema (
chrislema.com) does a great job of segmenting his email lists by frequency (weekly vs. daily) - his blog posts get populated into the email and he doesn't have to slave over each individual message.
If your sales funnel is robust, you can segment your list for the various points of your funnel and eventually you're only hitting the people who are ready to buy with your most aggressive sales content. This keeps your unsubscribe rate low and your conversion rate high.
