I couldn’t get my old eFax account working, so I did what most of us do when that happens in a time crunch… create a new trial account. Here is the email eFax shot over in an effort to aid in retention of trialers to buyers.

In this case, the idea is that the more people who have this fax number for you, the more likely you are to keep paying for it.
eFax simply took the time to tell trialers what behavior they desired.

Could something as slap-me-on-the-forehead simple work for your business?

It works for Sean at PsychoTactics – he asks for referrals and testimonials
It works for Chuck Green – he asks for folks to buy from his design store to support his free newsletters

Food for thought.
