Chatbot email verification with BillionVerify
Chatbot is an AI-powered chatbot builder for creating conversational experiences on websites and apps. Pairing it with BillionVerify means every email address your chatbot collects is checked for validity and deliverability before entering your marketing or support stack.
Why verify before the send
Chatbots are a high-volume entry point for contact data, and users frequently enter mistyped or temporary emails during chat. Without verification, your lists accumulate undeliverable addresses that hurt bounce rates and sender reputation. BillionVerify acts as a quality gate at the moment of collection.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Chatbot sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Chatbot
Ready-to-use workflows that verify emails before Chatbot sends.
How it works
- 1
Your chatbot captures a visitor's email address during a conversation.
- 2
The address is sent to BillionVerify using the REST API, n8n community node, or Integrately.
- 3
BillionVerify checks MX records, domain existence, disposable status, and syntax.
- 4
A pass or fail result is returned and used to route the data appropriately.
- 5
Verified emails are forwarded to your CRM or email platform; others are handled according to your rules.
When to use this
Screen emails at the chatbot entry point
Rather than discovering bad emails after a campaign bounces, verify them the instant your chatbot receives them. BillionVerify's real-time API fits naturally into the chatbot-to-CRM data flow.
Improve lead quality from conversational forms
Chatbots often replace traditional forms for lead capture. BillionVerify ensures the email leads coming through your bot meet the same quality standard you would expect from a form with server-side validation.
FAQ
Which integration method works best with Chatbot?
If you already use n8n, the BillionVerify community node is the most convenient option. For no-code setups, Integrately provides a one-click connection. The REST API works for custom implementations.
Can BillionVerify handle high traffic from a busy chatbot?
Yes. BillionVerify is built for scale, supporting single and bulk verification through the same API, so it handles traffic spikes without degrading response times.
Does verifying emails affect the chatbot user experience?
Verification can run asynchronously after the conversation ends, or inline with a response time that is fast enough to be imperceptible in most chat flows.
What is a catch-all domain and why does it matter?
A catch-all domain accepts email for any address at that domain, making it impossible to confirm delivery. BillionVerify flags these so you can decide how to handle them rather than assuming they are valid.
