I've been using MV since it debuted. It does exactly what it says it does - verifies millions of emails. Price-wise, it's the best-priced on the market, and can handle very large bulk requests in a reasonable time frame.

We have tried out a number of verification services over the past year. It's been amazing how much faster and more accurate this is so far. The service is great, our bounce rate went down significantly using their service.

Million Verifier is an excellent program I use to keep my email list fresh! The process is quick and delivers a report in 3-categories (good), (risky), and (bad). The cost is very economical for the peace of mind.
