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

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.
Common Questions About Clay + RocketVerifier
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/bulk for a single job, or use the rocketverifier CLI’s bulk create --file command.
