Proofy vs Kickbox Email Verification: Which is best for you?

Being able to delete email addresses that are closed or change regularly is very useful for lists containing several thousand contacts.

Proofy.io offers responsive support, fast and accurate email verification, and good overall value, though one drawback is that I sometimes end up paying for a high number of invalid emails

I like the capabilities of Kickbox Email Verification.

It also took quite a long time to clean lists with bad emails inside when compared to other services like Bouncer who is one of the slower ones.
