Why PAYG in Clay

Clay tables re-run enrichments. A monthly verifier seat bills quiet weeks; Verifly credits only move on live verifies and never expire across clients.

FAQ

Frequently asked questions

Where do I download the schema?

https://verifly.email/samples/clay-column-schema.json — column keys, HTTP map, and copy blocks for the verify step.

Instantly or Smartlead?

Same gate. Use Clay’s native Instantly/Smartlead actions and only fire when send_ready is true. See /use-cases/instantly-smartlead.

What about catch-all domains?

Map catch_all and decide per ICP whether to send, suppress, or route to a softer channel. Verifly returns the flag; your formula owns the policy.
