BillionVerifyChatgpt
Automate lead nurturing with ChatGPT-4o & Gemini for personalized email drafting
Pull contacts, verify each address with BillionVerify, and continue to ChatGPT — only deliverable addresses get through.
Why verify before the send
Sending to invalid, risky, catch-all, or disposable addresses spikes your bounce rate and erodes sender reputation. A verification gate before the ChatGPT step removes that risk automatically — only deliverable addresses continue, the rest are flagged.
The workflow
BillionVerify — verification sits right before the send.
Node by node

- 10Verify Email (BillionVerify)Verify· billionverify
The BillionVerify node verifies the address — status (valid / invalid / risky / catch-all / role / disposable), is_deliverable, and a confidence score — before anything is sent.
- 11IF deliverableLogic· n8n
Branches on the verification result: only deliverable addresses continue to the send; the rest are skipped and flagged.
- 12Create a draftSend· n8n
Sends only to verified, deliverable addresses. Swap in your own provider node if you send elsewhere.
- 13Append or update row in sheetSource· n8n
Provides or transforms the contact data flowing through the workflow.

FAQ
Why verify before sending in ChatGPT?
Verifying first keeps your bounce rate low, which protects your sender reputation and your results.
How do I import this workflow?
Download the JSON, then in n8n go to Workflows → Import from File (or paste it). Install the BillionVerify community node and add your API key credential.
What happens to risky or catch-all addresses?
They are routed to the false branch and excluded from the send. You decide whether to retry, review, or drop them.
