GTM & outbound agencies

Cheap pay-as-you-go email verification for GTM, Clay, and n8n pipelines

Outbound and GTM agencies live on enrichment volume: name + company → guessed emails → verify → push to sequence. Monthly verifier contracts punish bursty pipelines. Verifly is a flat, pay-as-you-go verify API built for Clay tables, n8n workflows, and agency tooling — buy credits when you need them, no seat tax.

The GTM agency pattern: enrich → verify → sequence

Modern outbound shops do not buy static lists anymore. They run enrichment: pull a company, guess email formats, verify which guess is real, then push survivors into a sequencer. Clay tables, n8n graphs, and custom scrapers all converge on the same bottleneck — a verify API that does not force a fat monthly contract when volume swings week to week.

That is the Rebar-style GTM workflow in one line: permutation + verification as a metered utility. Verifly is the verify half — HTTP Bearer API, batch and bulk endpoints, free trial credits, and public packs from $2/1k down to $0.60/1k with credits that never expire.

Wire Verifly into Clay or n8n in minutes

In Clay, add an HTTP API enrichment column that calls GET /api/v1/verify with your vf_ key and maps the verdict + catch-all / disposable flags into columns you filter on before export. In n8n, use the community node n8n-nodes-verifly or a plain HTTP Request node — same Bearer auth. Either way you only spend credits on rows that actually need a live check.

Create a free Verifly account and mint an API key (vf_…).
Add an HTTP / Verifly step after enrichment and before sequencer export.
Keep only deliverable (and optionally risky/catch-all) rows.
Buy a credit pack when volume ramps — no monthly minimum.

Batch-verify a Clay export 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","alex@acme.io","a.smith@acme.com"]}'

Why pay-as-you-go beats seat-based verifiers for agencies

Agency and GTM volume is lumpy: a client onboarding week can burn 50k verifies; the next fortnight is quiet. Seat or monthly-minimum products bill you for the quiet weeks. Verifly packs are prepaid credits with no expiry, so a $99 / 100k pack covers a bursty quarter across every client table you run.

Contact hello@veriflyemail.com if you need a higher spend cap or a dedicated key for a client workspace — same public pricing, no custom contract required to start.

FAQ

Frequently asked questions

Does Verifly work with Clay?

Yes. Call the Verifly HTTP API from a Clay enrichment column (or webhook). Map the verdict and flags into Clay columns, then filter before you export to your sequencer. See /clay-email-verification for a dedicated walkthrough.

Can I use Verifly inside n8n?

Yes. Install the community package n8n-nodes-verifly, or use a plain HTTP Request node against /api/v1/verify and /api/v1/verify/batch. Details live at /n8n-email-verification.

How is this priced for outbound agencies?

Public flat packs: Starter 5k/$10, then volume packs down to $0.60 per 1,000 at the largest size. Credits never expire. No monthly seat fee — you only buy when enrichment volume needs it.

Is there a free tier to test a Clay table?

New accounts get free trial credits so you can wire the HTTP step and validate verdicts on a sample table before buying a pack.

What about bulk lists from a CRM export?

Use the async bulk endpoint for up to 1,000,000 addresses, or batch (up to 100 per call) for ongoing Clay/n8n chunks. Same API key either way.
