I really like the very simple and navigational UI of Mailsfinder - Best Email Finder and Verification Tool. It helps me easily navigate through all the options on the UI front. Another thing I love is that the credits roll over, which is a really good feature. If I have, say, 50,000 credits and only use 20,000, the remaining 30,000 roll over to the next month. I also find it very easy to set up, as there's nothing complicated about it. Review collected by and hosted on G2.com.

I feel like they could add domain search because right now, it is not there. If I just have a domain name, then I want to have a list of emails through that domain. So that's the feature that I want in Mailsfinder. Review collected by and hosted on G2.com.
