Great tool. Easy to use and it always works fine. The pricing is very reasonable. What I like most about proofy is that, if you don't use all of your credit in a month, it won't reset as most of the tools do.

Thank you! Have a great day!
I send more than 1,000 cold emails every day. I wouldn't be able to have my emails landed directly in inboxes without thoroughly validating them. Even though there are many email validation tools on the internet, the only one I can vouch for is Proof.
