No test emails
Email Intel does not send a message to the target address to manufacture a delivery outcome.
Software early access Email verification API
An API for the records binary tools
leave unresolved.
Email Intel is an evidence-first email verification API for B2B workflows where syntax and SMTP behavior are not enough. Instead of forcing every address into valid or invalid, the response preserves confidence, supporting and contradicting signals, and an operational recommendation.

01 / The decision
A catch-all server response is not a mailbox verdict.
On an accept-all domain, the mail server accepts every address during verification. A real mailbox and a fictional one can produce the same response, so a binary API either admits uncertainty or hides it inside a score.
Email Intel combines domain infrastructure, public naming patterns, identity and company evidence, authentication posture, and—where a customer explicitly connects it—their own consented delivery outcomes. Weak or contradictory evidence returns review, not manufactured certainty.
01Explicit recommendation
Route each record to use, suppress, correct, review, or recheck.
↗02Explainable evidence
Keep the signals and contradictions behind the result instead of storing only a black-box score.
↗03Catch-all resolution fields
When a domain accepts everything, the response still says whether the mailbox was resolved and at what confidence.
↗04Workflow-ready output
Use synchronous decisions for forms and CRM actions, or batch scoped lists for review.
↗02 / Operating boundaries
Useful because the limits
are visible.
Unknown is supported
When the available evidence cannot discriminate, the API can return an inconclusive state your workflow can route safely.
Method before marketing claims
We do not publish a head-to-head accuracy claim until a replacement benchmark uses observed customer delivery outcomes.
03 / Questions buyers ask
Clear answers before
you commit.
What makes this email verification API different?
The response is designed for a decision audit trail: result, confidence, catch-all resolution fields, and optional weighted signals. It does not include a per-signal timestamp. The focus is the catch-all and ambiguous B2B segment ordinary binary verification handles poorly.
Does the API send test emails?
No. The target mailbox does not receive a test message from the verification workflow. Consented customer delivery outcomes may strengthen later decisions only when that customer connects its own data.
Can I use it with HubSpot?
Yes. Start with a scoped audit or API workflow, validate the decision policy, and then map results into HubSpot properties and automation. That sequence avoids automating an unproven rule across the CRM.
