How we compare
Built different.
Most companies relying on email miss on average 25% of their revenue due to poor data. Our API is built to interpret modern identity and email infrastructure stacks to return live, accurate data; helping with fraud prevention, marketing efforts and underwriting.

Why it resolves better
Live verification, not stale lookup tables.
01
No database layer
Results are produced from live provider and mailbox checks instead of stale dumps, recycled enrichment tables, or purchased address inventories.
02
SMTP-only has blind spots
SMTP probing can surface deliverability but it cannot reliably map a mailbox to a real identity once gateways, catch-all behavior, and modern login stacks get involved.
03
Identity checks expose aliases
Relentless Identity correlates provider-side identity evidence with live routing signals, which is why it can resolve aliases and distinguish valid users from generic catch-all responses.

How it works
Three steps. Precise Response.
1
Submit
Provide either a name, company domain pair or an email address.
2
Classify
Performs domain discovery before verifying against the person or given identity.
3
Verify
For finder calls, it'll look for related email domains and for an identity across them. For individual probe calls, it'll confirm wether the particular identity exists or not for the given email domain.
