I like how you can enter many email addresses to see if they are legit.I also enjoy how it instantly brings up if the data is valid or not. They have a nice look, which is always important to everyone. Review collected by and hosted on G2.com.

I don't like the customer service they have, it is usually very slow. They take time to answer. There isn't a lot to differentiate from other companies who do the same thing. Review collected by and hosted on G2.com.
