Never assume, he said, that:
-All eyeballs are created equal
-The last click should get all the credit (There are many activities that are valuable which don't drive specific conversions, like thanking renewing customers or sending birthday wishes)
-Targeting does not matter with inexpensive media like email (It does! Consider that relevancy is the single biggest driver of both inbox placement and response.)
-The winning version for clicks may not be the winner on conversion
-All your customers will utilize your preference center (Marriott advises not to expect more than 20% to visit.)
- Your customers won't notice if you collect data and don't use it (They will!)
- Your best channel is ALWAYs your best channel (e.g.: if your content is "stale" after 24 hours then a text may be better than email)
- Channels work alone (It's not a single exposure that motivates action).
