Verify enriched emails in Clay before you export to outreach

Clay finds and enriches emails at scale, but enrichment providers guess — they don’t confirm deliverability. Add a RocketVerifier "HTTP API" enrichment column so every row gets a live classification and confidence score before it’s exported to Smartlead, Instantly, or your CRM.

Example, inside Clay:

"Find Email (Clay) → RocketVerifier HTTP API column → Filter table where Email Status = "valid" → Send to Smartlead"

Clay calls RocketVerifier's verification API for you and hands back a clean, classified result — no dashboard upload, no manual CSV round-trip.

Get an API key

Add an HTTP API column

In your Clay table, add an enrichment column of type "HTTP API" pointed at /v1/verify with your API key.

Filter before you export

Filter or sort the table on the classification column so only send-safe emails leave Clay for your outreach tool.

Clay "HTTP API" enrichment column:

Method:  POST
URL:     https://api.rocketverifier.com/v1/verify
Headers: Authorization: Bearer rv_live_your_api_key
Body:    { "email": "{{Email}}" }

Map output fields:
  classification → new column "Email Status"
  score          → new column "Confidence Score"

Full setup guides are in the MCP documentation and API reference.

Confidence scores, not guesses

Every result comes back with a 0–100 score and evidence — SMTP response, provider detection, DNS records — so Clay can make the send/skip call.

Idempotent by default

Every write request auto-generates an Idempotency-Key, so a retried or automated call can never double-charge credits or create duplicate jobs.

Never pay for a non-answer

Unknowns and duplicates are always free — unlike incumbents that charge for "risky" or "unknown" results your workflow can't act on.

FAQ

Clay verification FAQ

Why verify emails that Clay already found?

Clay’s waterfall enrichment finds likely emails from multiple data providers, but "found" isn’t "deliverable" — RocketVerifier confirms mailbox status in real time before you spend outreach volume on it.

Does this work with Clay’s credit-based pricing model?

Yes — RocketVerifier credits are separate from Clay credits. You only spend a RocketVerifier credit per email actually checked, and unknowns/duplicates are always free.

Can I bulk-verify an entire Clay table at once instead of row by row?

Yes — export the table’s email column and submit it to POST /v1/verify/batch for a single job, or use the rocketverifier CLI’s bulk create --file command.
