We ran the test at ColdIQ to find as many emails as possible with 6 other email finders from a 10000 leads list.

After finding around 7k emails, we checked If Prospeo could find the remaining 3000

Prospeo managed to find the 25% that no one else got. 717 verified emails that only Prospeo could find

Prospeo finds on average 33% more valid emails

In a study conducted by Eric Nowoslawski and Clay.com, Prospeo outperformed its competitors, securing an impressive lead with 33% more email discoveries.

Built-in accurate email verification

When Prospeo.io tag an email as valid, the email was freshly verified and have a less than 2% bounce risk.

As most email verifier uses old-school methods and outdated algorithm to verify email addresses, using other verification tools on top of our valid email will cause you to lose on valid email.

We advise against re-verifying our email: it will cost you more, will making you lose exclusive valid email.

Below is how other email verifier will tag real emails (that responded to a live email, truly valid):
