I'm sending the emails directly from my server with the unix "mail" utility.

Ending up in spam is actually what most concerns me about this idea, and in fact this concern was what led me to choose the "you don't pay unless someone clicks on a link" pricing--I was worried that some of the emails might eventually start ending up in spam after a few customers and wanted to make sure I wouldn't be charging people if that happened.

I'm planning to see what works once/if the phishing emails actually start ending up in spam.
