Verify Clay enrichment rows before Instantly / Smartlead import

#saas #api #tutorial #productivity

Outbound teams living in Clay do the same loop every week: enrich a company, guess emails, verify which ones are real, then push survivors into Instantly or Smartlead. The verify step is where monthly-contract tools punish you — volume spikes on client onboarding weeks and goes quiet in between.

Verifly is a pay-as-you-go email verification API built for that pattern. Credits never expire, public packs start cheap, and the surface is a plain Bearer HTTP API you can call from a Clay HTTP enrichment column, an n8n node, or a CSV cleaner before sequencer import.

Clay HTTP enrichment in 4 steps

  1. Mint a free API key at verifly.email (trial credits included).
  2. In Clay, add an HTTP API enrichment after your email finder / permutation column.
  3. Call: 
curl -X GET "https://verifly.email/api/v1/verify?email={{Email}}" \
  -H "Authorization: Bearer vf_your_api_key"
Enter fullscreen mode Exit fullscreen mode
  1. Map result, disposable, role, and catch-all flags into Clay columns. Filter to deliverable (and optionally keep risky / catch-all depending on how new your sending domain is) before you export.

Batch a Clay export

When you leave the table, batch-verify a chunk:

curl -X POST "https://verifly.email/api/v1/verify/batch" \
  -H "Authorization: Bearer vf_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{"emails":["alex@acme.com","a.smith@acme.com","asmith@acme.io"]}'
Enter fullscreen mode Exit fullscreen mode

For larger jobs, use the async bulk endpoint (up to 1,000,000 addresses). Same key, same credit pricing.

Instantly / Smartlead handoff

Export the filtered Clay view (or the cleaned CSV) and import only survivors. Sequencers amplify bad data — stripping undeliverable and disposable addresses before import protects domain warmup more than any post-send bounce dashboard.

Pricing shape for agency volume

Public packs: Starter 5k/$10, then volume packs down to about $0.60 per 1,000 at the largest size. No monthly seat fee. Buy when a client workbook ramps; credits sit unused when it is quiet.
