What people say
"I tried one of those 'free' WordPress newsletter plug-ins. Several hours later, I still couldn't get it to work. Talk about a costly endeavor! Tribulant, on the other hand, worked from the get-go. And the customer support is among the best I've ever seen. My advice: End your search here. You've found your WordPress newsletter plug-in."
