Seemed like it was worth a try. The price sounded good. Seemed like it could potentially be a better deal than my current one... it wasn't.
First of all, they took a time-tested, carefully vetted list which had 0 complaints for the past 4 months and
demonstrated that their bounce rates were 4x higher than I was used to. Then, they suspended my account after 800 emails were sent (out of 32,000). Not very impressive. Not worth the time and effort, and it was free. They were even bouncing emails sent to old friends whose emails I knew for a fact were correct.
