The numbers speak for themselves.

In early benchmarks performed against market leaders*, 250ok discovered:

Other vendors are misclassifying deliverable addresses.

Up to 2% of the addresses a leading vendor classified as undeliverable were actually valid addresses.

Send to more: Of a list of 10 million email addresses, this could mean other vendors are telling you not to send to nearly 200,000 deliverable addresses.

On a massive scale.

Other vendors have, on average, 9x the unknown (unmatchable) addresses as 250ok (with a peak of 15x). Of those unknown addresses, up to 75% are deliverable.

Send with more confidence: Increased accuracy in our data and our processes allows you to send to more of the email address others are unable to successfully classify.


250ok is better at finding bad addresses.

We're up to 40% better at identifying undeliverable addresses than leading validation providers.

Send with more confidence: We're better at catching the undeliverable, addresses which could harm your reputation if sent to.

A lot better, actually.

In one test, 99.5% of the addresses one vendor identified as “high risk” were actually Verified Vaild.

Send to more: While others may not have the data to determine real risk, 250ok's Verified Valid can not only find you more deliverable addresses but addresses who have demonstrated recent engagement activity signals.

* Based on research performed by 250ok’s proprietary multi-step validation process on 1,054,000 email addresses against industry-leading email validation vendors, June 2019.
