🧱 Automation Platform · HTTP API / webhook step

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.

2

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.

3

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

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.
