What is an outsourced newsletter?

All I can say is that the nurseries/garden centers in my area have been soured on the whole idea of them. I came up with the idea of a gardening tabloid focused on this region and when I waltzed it around to get business support they all shunned me. They thought I was offering "yet another" customized newsletter for their business. Evidentally they get hit on frequently and I never got to explain myself. The only way to convince them of the difference was to just publish without them and show them.
