RECOMMENDATIONS
Skip the typical bs -- i.e., generic email blasts to non-segmented lists.

Start with laser focus ...
- Send a highly personalized email to a very specific segment of your list.
- Then optimize by tweaking that send (over time) until you achieve an acceptable open rate (>30% -- average is 20.81%, but we don't believe in 'average', so ...)
- AND, more importantly, tweak that send until you achieve an acceptable click-through-rate (>3%? -- only you know what's acceptable here).
