Create AI personalized video & voice outreach with HeyGen, ElevenLabs & Perplexity
Pull contacts, verify each address with BillionVerify, and continue to HeyGen — 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 HeyGen step removes that risk automatically — only deliverable addresses continue, the rest are flagged.
The workflow
BillionVerify — verification sits right before the send.

FAQ
Why verify before sending in HeyGen?
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.
