Which result should I keep?

Send to deliverable only for cold outreach. Treat risky (catch-all) as a separate, low-volume segment. Drop undeliverable. unknown and catch-all checks cost 0 credits.

Cost

1 credit per definitive check. Packs from $10 for 5,000 to $599 for 1M; credits never expire and there is no subscription. A 2,000-row Sheet costs at most 2,000 credits.

FAQ

Frequently asked questions

Do these work on self-hosted n8n?

Yes. They only use core nodes (Webhook, HTTP Request, IF, Code, Google Sheets). If env access is blocked on your instance, paste the key into a Header Auth credential instead.

What happens if I run out of credits?

The API returns HTTP 402 with error.code insufficient_credits; the templates use neverError so the flow continues and marks the row instead of crashing.

Is there a rate limit?

Batch: 10 requests/second per account, 100 emails each. The Sheets template already throttles to 5 checks per second.
